1.3 General Description
1.3.1 BNP blast cabinets enclose the blasting
environment to provide efficient blasting while maintaining a clean surrounding work area. Production rates are influenced by size of nozzle, compressor output, working pressure, type and size of media, angle and distance of the nozzle from the blast surface. BNP pressure cabinets consist of four major components:
1. Cabinet Enclosure
2. Reclaimer
3. Blast Machine
4. Dust Collector
1.3.2 Cabinet Enclosure: This manual covers two BNP cabinet sizes. Each is available as a conventional, stand-up model and ergonomic, sit-down model; totaling four separate cabinet models.
BNP 65 Approximate work chamber dimensions: 36" wide x 35" deep x 37" high.
BNP 220 Approximate work chamber dimensions: 50" wide x 39" deep x 43" high.
NOTE: The extended front on ergonomic models provides approximately 12-inches additional depth from the arm-port and above, and is approximately 3-inches narrower than the widths shown above.
Refer to Figure 1 for arrangement of components with a CDC-1 dust collector. Figure 2 shows the arrangement with a RPC-2 reverse-pulse dust collector with dust
drawer. The optional RPH-2 is set up the same way

as the RPC, but includes a hopper for additional dust storage, and empties into a drum. The overall height of the RPH is approximately 10-feet, 6-inches, and 12-ft when the top access door is open. An upgraded, RPC or RPH collector may be added at any time.
1.4 Theory of Operation
1.4.1 Once the components are correctly setup and
turned on, the cabinet is ready for operation by actuation of the foot pedal. Fully depressing the foot pedal pressurizes the blast machine, causing the media to be propelled through the blast hose and out the nozzle. After striking the object being blasted, the blast media, fines, dust, and by-products generated by blasting, fall through the mesh worktable into the cabinet hoppers. These particles are then drawn into the reclaimer for separation. Lightweight dust and fines remain airborne and are drawn out to the dust collector. Heavier reusable media fall through the screen into the reclaimer hopper for reuse. The dust collector traps dust and fines and discharges clean air. When the foot pedal is released, blasting stops.
1.5 Blast Machine and Controls
1.5.1 Clemco blast machines (pressure vessels) are
certified to conform to the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code, Section VIII, Division 1. It is the owner’s responsibility to maintain the integrity of the vessel in accordance with the requirements of state regulations. Regulations may include regular inspection and hydrostatic testing as described in National Board inspection code and jurisdictional regulations and /or Laws.
WARNING
Welding, grinding, or drilling on the blast machine could weaken the vessel. Compressed air pressure could cause a weakened blast machine to rupture, resulting in death or serious injury. Welding, grinding, or drilling on the vessel, without a National Board R stamp, voids the Clemco ASME certification.
© 2016 CLEMCO INDUSTRIES CORP. www.clemcoindustries.com Manual No. 21278, Rev. H, 08/16
BNP 65P and 220P PRESSURE BLAST CABINETS Page 3
1.5.2 All welding repairs to the vessel must be
performed by certified welders at shops holding a National Board R Stamp. Welding performed by any welder not properly qualified per the ASME code voids the Clemco ASME certification.
1.5.3 Do not exceed the maximum working pressure
rating (PSI) of the blast machine. The maximum pressure rating is stamped into ASME nameplate which is welded to the side of the vessel.
WARNING
Excessive compressed air pressure could cause a blast machine to rupture. To prevent serious injury or death, do not exceed the rated pressure of the blast machine.
1.5.4 OSHA does not require pressure relief valves
on blast machines when air compressors supplying air
(1)
to the blast machines are built to ASME comply with OSHA
(2)
regulations. OSHA regulation
code and
1910.169 refers to the ASME code when describing the necessity of pressure relief valves on compressed air
equipment. DO NOT operate blast machines with air
compressors that are not equipped with properly­functioning pressure relief valves.
(1)
American Society of Mechanical Engineers, Boiler and Pressure
Vessel Code, Section VIII, Division 1,
(2)
Occupational Safety and Health Administration, 29 CFR 1910, 169.
1.5.5 When the cabinet is setup, the blast machine is
ready to blast by actuating the foot pedal. Pressing the foot pedal opens the normally closed main inlet regulator, and closes the normally open outlet valve. The incoming air pressurizes the blast machine, and blasting begins. When pressure on the foot pedal is released, the blast machine depressurizes, and blasting stops.
1.6 Dust Collector Options
WARNING
Prolonged exposure to any dust could result in serious lung disease and death. Short term ingestion of toxic materials, such as lead dust or dust from other heavy metals and corrosives, could cause serious respiratory injury or death. Identify all materials that are to be removed by blasting. Use reverse-pulse dust collectors with HEPA after-filters if lead coating or any other toxic materials are being removed by the blasting process. Do not use dry filter dust collectors for those applications.
© 2016 CLEMCO INDUSTRIES CORP. www.clemcoindustries.com Manual No. 21278, Rev. H, 08/16
1.6.1 CDC-1 Dust Collectors: Shown in Figure 1, the
collector is available in 600, and 900 cfm models. The single filter cartridge is cleaned by using a manually­controlled pulse of compressed air. CDC-1 dust collectors are standard with BNP cabinets unless an optional RPC-2 or RPH dust collector is ordered at time of purchase. Refer to manual number 28225.
1.6.2 RPC-2 Dust Collectors: Shown in Figure 2,
this collector is available in 600 cfm and 900 cfm models. Dual filter cartridges are automatically cleaned by a timed, periodic pulse of compressed air. Dust collects in the drawer and must be frequently emptied. Refer to manual number 22788.

1.6.3 RPH-2 Dust Collector: The RPH-2 is available
in 600 cfm and 900 cfm models. It is set up and operates the same as the RPC-2, as shown in Figure 2, but instead of a dust drawer, the collector sits atop a hopper, which provides additional dust storage, and empties into a drum. Refer to manual number 21449.
1.6.4 HEPA (high-efficiency particulate air) Filter:
HEPA after-filters provide additional filtration and must be used with a reverse-pulse cartridge collectors when removing lead coatings or any other toxic materials. HEPA filters are listed under Optional Accessories in Section 9.1.
1.7 Reclaimer Options
1.7.1 Replaceable rubber reclaimer liners prolong
service life of the reclaimer, and should be installed when using silicon carbide, aluminum oxide, or other aggressive media as noted in Section 1.10.4. Rubber liners are available for 600 and 900 cfm reclaimers that
BNP 65P and 220P PRESSURE BLAST CABINETS Page 4
have a removable top and are designed to accept liners. Reclaimer liners are shown in Section 9.1, Figure 30.
1.8 Nozzle Options
1.8.1 Unless otherwise specified at the time of
purchase, cabinets are shipped with a 3/16" orifice tungsten carbide nozzle. Optional 1/8" orifice nozzles are available for use with all cabinets, and 1/4" orifice nozzles are for use with 900 cfm reclaimers only.
1.8.2 Nozzles with an orifice larger than those
recommended could cause air leakage from the cabinet
and impair recovery from the cabinet hopper.
1.8.3 Use boron carbide nozzles when blasting with
aggressive media, as noted in Section 1.10.4. Nozzles lined with boron carbide extend nozzle wear life. Refer to Optional Accessories in Section 9.1.
1.9 Metering Valve Options
1.9.1 Unless specified at the time purchase, cabinets
are supplied with a fine-mesh Sentinel metering valve. The valve is for use with 50-mesh and finer media, and #10 and finer glass bead. The optional Sentinel metering valve is recommended when using media coarser than 50-mesh. Conversions kits listed in Section
9.1 easily convert the valves.
1.10 Blasting Media
WARNING
Obtain Safety Data Sheets (SDS) for the blast abrasive. Abrasive blasting with sands containing crystalline (free) silica can lead to serious or fatal respiratory disease. As NIOSH recommends, do not use abrasives containing more than trace amounts (more than one percent) free silica.
NOTE: Use only abrasives specifically manufactured for blast cleaning which are compatible with the surface being blasted. Abrasive produced for other applications may be inconsistent in size and shape, contain particles that could jam the abrasive metering valve, or cause irregular wear.
1.10.1 ZERO pressure blast cabinets utilize most
common reusable media, with the appropriate metering valve as noted in Paragraph 1.9, specifically manufactured for dry blasting. Media sizes listed are guidelines only, based on standard 3/16 orifice nozzle and average conditions, such as blast pressure, media/air mixture, visibility inside the cabinet, humidity, and reclaimer cleaning rate. Refer to the table in Figure 3.
© 2016 CLEMCO INDUSTRIES CORP. www.clemcoindustries.com Manual No. 21278, Rev. H, 08/16
Several factors affecting the reclaimer cleaning rate include: reclaimer size (cfm), blast pressure, media/air mixture, media friability, contamination of parts being cleaned, damper setting (static pressure), and dust collector filter loading (differential pressure across the filter cartridge(s).
As a rule, larger nozzles deliver more media, thus requiring more performance from the reclaimer. When using larger nozzles, the maximum mesh size of media will be smaller than those normally recommended. Using media that is finer than those recommended may decrease visibility and, at some point, carryover to the dust collector. Media coarser than those recommended may be too dense for the reclaimer to recover from the cabinet hopper.
1.10.2 Steel and Shot: Standard cabinet models configured for steel media use are available. They include appropriately sized conveying hose and rubber curtains to protect the cabinet walls from peening and rapid wear.
Using steel media requires a smaller diameter conveying hose (usually reduced one size from standard) and a 900 cfm or larger reclaimers. Rubber curtains should be used to protect the cabinet walls from peening and rapid wear. NOTE: Steel grit or shot is too heavy to use with cabinets equipped this 300 and 600 cfm reclaimers.
1.10.3 Sand and Slag: Sand should NEVER be used
for abrasive blasting because of the respiratory hazards associated with media containing free silica. Slags are not recommended because they rapidly breakdown and are not recyclable, making them unsuitable for cabinet applications.
1.10.4 Silicon Carbide, Aluminum Oxide, and Garnet: These are the most aggressive of the
commonly-used media. Aggressive media may be used,
but the service life of any components exposed to the media will be reduced. To avoid unscheduled down time, periodically inspect the reclaimer wear plate, blast hose, and nozzle for wear.
When using aggressive media only occasionally, install an optional aluminum oxide kit. The kit includes rubber curtains for the cabinet interior and a boron carbide-lined nozzle. When using aggressive media on a regular basis, install the aluminum oxide kit and a fully-rubber-lined reclaimer. NOTE Rubber-lined reclaimers are available as factory-installed items and can be field installed on reclaimers if they have removable tops and designed to accept liners. Nozzles lined with boron carbide extend nozzle wear life. See Optional Accessories in Section 9.1.
1.10.5 Glass Bead: Most beads are treated to ensure
free-flow operation even in environments of moderately high humidity. Glass beads subjected to excessive moisture may be reused only after thorough drying and breaking up any clumps.
BNP 65P and 220P PRESSURE BLAST CABINETS Page 5
This table offers a guideline to media selection based on standard 3/16” orifice nozzle (3/8” with plastic and similar weight media blasting at low pressure) and average conditions, such as air pressure, media/air mixture, visibility, contamination of parts being blasted, humidity, media friability, reclaimer cleaning rate, etc. As a rule, larger nozzles deliver more media, requiring higher performance from the reclaimer. Larger nozzles decrease the maximum mesh size of media from those recommended. Media that is finer than those recommended may decrease visibility and carryover to the dust collector. Media coarser than those recommended may be too dense for the reclaimer to recover from the cabinet hopper

1.10.6 Lightweight and Fine-mesh Media: When
using lightweight (such as agricultural) media or fine mesh (180-mesh and finer) media, the reclaimer inlet baffle may need to be removed to retain media and avoid carryover. On reclaimer models with bolt-on removable topes, baffle removal and replacement is easily accomplished. Reclaimers with welded-on tops require grinding to remove the baffle and once it is removed it cannot be replaced.
1.10.7 Plastic Media: Plastic and similar media
requires a blast machine with a 60 degree conical bottom. Refer to Clemco’s AEROLYTE cabinet brand.
1.10.8 Bicarbonate of Soda: Bicarbonate of soda is
not recommended for use in standard cabinets. Bicarb is a one-use media usually used and will quickly saturate the filter cartridge(s). Refer to Clemco’s AEROLYTE cabinet line for cabinets that are specifically designed for use with bicarbonate of soda.
1.11 Compressed Air Requirements
1.11.1 The size of the compressor required to operate
the cabinet depends on the size of the nozzle and blasting pressure. Unless otherwise specified, cabinets are supplied with a 3/16" orifice nozzle. The table in Figure 4 shows air consumption of nozzles when new. It does not show the recommended compressor size. As nozzles wear, they will consume up to 70% to 80% more air. Consult with a compressor supplier for a suggested compressor size based on the air consumption.
NOTE: A separate air line is required for the reverse­pulse dust collector.
MEDIA TYPE
Compressed Air Consumption *(cfm)
Nozzle Air Pressure (psi) size 50 60 70 80 1/8" 11 13 15 17 3/16" 26 30 33 38 1/4" 47 54 61 68
* Figures are approximate and for reference only, and may vary for different working conditions. Several variables, including media flow and nozzle wear affect cfm consumption.
Figure 4
1.11.2 The air filter at the blast machine inlet removes
condensed water from the compressed air. The filter automatically drains when moisture fills the bowl to a certain level. Its use is especially important in areas of high humidity, or when fine-mesh media are used. Moisture causes media to clump and inhibits free flow through the metering valve. If the filter does not remove enough moisture to keep media dry and flowing, it may be necessary to install an air dryer or aftercooler in the air supply line.
1.12 Electrical Requirements
All wiring external to the cabinet is provided by the user to comply with local electrical codes.
1.12.1 Electrical requirements depend on the size and
phase of the dust collector exhauster motor. NOTE: Full load amps (FLA) shown below are for the motor only; the lights draw less than one amp. Standard cabinets are supplied as follows:
600 cfm: 1 HP, 115/230V, 1-PH, 60 HZ 115, FLA 115/12, 208/6.6, 230/6.2.

Additional wiring information is in Section 2.11.
2.0 INSTALLATION
2.1 General Installation Notes
2.1.1 Refer to Figure 1 (and Figure 2 for optional
reverse-pulse collector) for the general arrangement and Figure 5 for the control line schematic. Select a location where compressed air and electrical service are available. The cabinet location must comply with OSHA and local safety codes. Allow for full access to all doors and service areas and for efficient handling of large parts. Provide enough clearance in front of the dust collector to remove the dust drawer without tipping. Ideally, locate the blast machine directly behind the cabinet with the blast hose connection toward the cabinet. The reclaimer may be rotated on the blast machine to make hose connections with as few bends as possible. Determine the best location for all components and position them before making compressed air connections, electrical connections, and attaching flex hose.
2.1.2 Refer to the dust collector owner’s manual to set
up the dust collector and prepare it for operation.
2.2 Assemble Blast Machine and Reclaimer
2.2.1 Apply adhesive-backed strip gasket to the top of
the flange on the blast machine. Punch out an opening at each bolt hole.
2.2.2 If the optional storage segment is used, place it
on the blast machine. The access door should be on the bottom, and rotated to allow access to the door. Bolt into place. Apply adhesive-backed gasket to the top flange as described in Section 2.2.1.
2.2.3 Use a lift, raise the reclaimer over the blast
machine assembly, and lower it in place. Attach with fasteners provided.
WARNING
Do not work under the reclaimer while it is hanging from the lifting device. Severe injury or death could occur if the reclaimer is released before it is secured to the blast machine.
2.3 Support the Blast Machine
2.3.1 Use chains cables or other means to temporarily
support the blast machine and reclaimer during final assembly.
2.4 Connect Conveying Hose
2.4.1 Connect the smaller diameter, light-lined, flexible
conveying hose between the cabinet hopper transition and reclaimer inlet adaptor, and connect the larger diameter hose between the reclaimer outlet and dust collector inlet. It is easier to slip the hose over the adaptor and create a tighter seal if the first two or three inches of wire are removed from the inside of the hose. Use care not to damage the hose. Clamp flex hose securely in position with worm clamps provided. NOTE: The wire helps dissipate static electricity in the conveying hose, and also helps ground each segment. In order for the hose wire to dissipate static electricity, the wire must touch the metal of each segment.
2.5 Connect Blow-Off Hose
2.5.1 Attach the 1/2" blow-off hose coming from the
cabinet hopper, to the compatible fitting on the blast machine piping, between the air filter and pressure regulator. Refer to the schematic in Figure 5.
2.6 Connect Blast Hose
WARNING
Hose disconnection while under pressure could cause serious injury or death. Use safety lock­pins and safety cables on all coupling connections to help prevent hose couplings from accidental disconnection while under pressure. Lock-pins and safety cables are listed under Optional Accessories in Section 9.1.
2.6.1 Connect the blast hose from the cabinet hopper
to the coupling at the bottom of the blast machine. Make sure coupling gaskets are in place and couplings are secured with safety lock-pins.
2.7 Attach Blast Machine Exhaust Hose
2.7.1 Screw the male end of the exhaust hose into the
1" coupling in the hose adaptor plate, located on the cabinet hopper, turning the hose as required. Connect the female swivel end to the male adaptor on the blast machine outlet valve.

To avoid the risk of injury from compressed air, install an isolation valve and bleed-off valve where the air supply is tapped into the compressed air system. This enables depressurization of the compressed-air lines before performing maintenance.
2.9.2 Install an isolation valve at the air source to
enable depressurization for service, and connect a 1" ID or larger air line from the air source to the air filter on the blast machine. A smaller diameter hose may reduce blasting efficiency.
2.9.3 Refer to the dust collector owner’s manual and
connect a compressed-air line to the pulse manifold.
2.10 Ground Cabinet
2.10.1 To prevent static electricity build up, attach an
external grounded wire from an earth ground to the grounding lug on the left rear of the cabinet.
2.11 Connect Electrical Service
Shorting electrical components could result in serious electrical shocks, or equipment damage. Electrical power must be locked out and tagged out before performing any electrical work. All electrical work or any work done inside a control panel or junction box must be performed by a qualified electrician, and comply with applicable codes.
WARNING
WARNING
All wiring external to the cabinet is provided by the user to comply with local electrical codes.
2.11.1 Single-Phase Wiring
2.11.1.1 Standard 300 cfm 600 cfm cabinets and dust
collectors are 115-volt single phase. Incoming power to the cabinet is supplied by a U-ground plug; plug it into a
115-volt outlet.
WARNING
Do not use electrical adaptors that eliminate the ground prong on 115 volt plugs. Doing so could cause electric shock and equipment damage.
2.11.1.2 Refer to the wiring schematic in Figure 7 and
wire the dust collector motor per instruction on the motor data-plate, to the junction box mounted on the cabinet. When wired as noted in Figure 7, the dust collector exhauster motor will start when the cabinet light switch is turned ON, and stop when the switch is turned OFF.

drains, the water will drain into the pail.
2.14.2 Position the foot pedal on the floor at the front of
the cabinet or on the foot shelf on ergonomic models.
2.14.3 A package of five view-window cover-lenses is
supplied with the cabinet. Install a cover lens per Section 7.2. When the cover lens becomes pitted or frosted, replace it.
3.0 FIELD INSTALLED ACCESSORIES
3.1 Aluminum Oxide Kit
3.1.1 An optional aluminum oxide kit is available
factory installed or may be field installed later.
Filed-installed (or replacement factory installed) kits consist of black rubber curtains with grommets, curtain hardware, boron carbide nozzle and light-lined flex hose. If the existing flex hose is in good condition, reserve the new hose for future replacement.
3.2 Curtain Installation
3.2.1 Match curtains to corresponding wall and doors.
3.2.2 Front and rear walls: Position the curtain on
the wall to be protected. Using the curtains as templates, mark each mounting point through the grommet holes along the upper edge of the curtain. NOTE: When laying out the attachment points, the upper edge of the rear curtain should be below the bottom edge of the air duct partition. Remove the curtains, and drill a .187" (3/16") diameter hole at each point marked. Install the curtains using the fasteners

est
provided (machine screw, 11/16 OD flat washer, lock washer and nut) at each grommet. The flat washer is used between the screw head and the rubber curtain grommet on all curtains.
3.2.3 Doors: Using protectors against the curtains
and outer doors, clamp the door curtains in place. NOTE: When laying out the attachment points, the upper edges of the door curtains should be even with the outer edges of the door’s sound proofing panel. Insert a #10 self-drilling screw with an 11/16 OD flat washer through the grommet holes. Use a screw gun with a 5/16" socket to drill and thread the screws through the door’s inner wall at each grommet.
3.2.4 Ergo Side Extensions: Position the curtain on
the wall to be protected. Use the curtain as a template and mark the top mounting point through the grommet. Remove the curtain, and drill a .187" (3/16") diameter hole at each point marked. Install the curtains using the fasteners provided (machine screw, 11/16 OD flat washer, lock washer and nut) at each grommet. The flat washer is used between the screw head and the rubber curtain grommet on all curtains. After the curtain is hung, mark and drill the cabinet and attach the lower grommets in like manner.
3.3 Manometer The optional manometer kit is listed in Section 9.1.
3.3.1 Consistent static pressure is necessary for
precise media separation, as the reclaimer's efficiency is achieved by a centrifugal balance of air flow, particle weight, and size. The manometer measures static pressure. Reclaimer static pressure is set by adjusting the dust collector damper. Refer to Section 5.3 to adjust static pressure. Refer to Section 5.7 for manometer instructions.
3.4 Armrest

4.0 OPERATION
4.1 Media Loading and Unloading
4.1.1 Media Capacity: Media capacity depends on
the reclaimer size. Media capacity of 600 cfm units is approximately 1.6 cu. ft. Full capacity will be below the opening of the pop-up valve. Capacity of 900 cfm units is approximately 2.0 cu. ft. Full capacity is when media is at level of the pop-up valve.
4.1.2 Media Loading: With the exhauster OFF, add
clean dry media by pouring it into the reclaimer hopper
through the reclaimer door. Do not pour media directly into the cabinet hopper, as over filling may occur.
Overfilling will result in media carryover to the dust collector and possible blockage in the conveying hose. Refill only after all media has been recovered from the cabinet.
4.1.3 Media Unloading: To empty the cabinet and
blast machine of media, turn the exhauster ON and blow-off the cabinet interior until all media is recovered from the cabinet. Reduce pressure to 40 psi. Place an empty container, such as a bucket, on the cabinet grate. Remove nozzle and nozzle washer, close the door, close the choke valve and press the foot pedal. Direct media flow into the container. Empty the container when full or before it is too heavy to handle, and repeat the process until the machine is empty. Return the choke valve to the full open position. Clean the nozzle holder threads and inspect the threads on the nozzle and nozzle holder before reinstalling the nozzle washer and nozzle. If complete purging of media is required, use a vacuum to clean media residue in cabinet hopper and blast machine head.

WARNING
Use solid fixturing to hold heavy parts in place. Do not remove lift equipment until the part is adequately supported to prevent movement. Moving heavy, unsupported parts may cause them to shift or topple, and cause severe injury. This is especially important with the use of turntables and turntables with tracks.
4.2.1 Load and unload parts through either door.
4.2.2 Parts must be free of oil, water, grease, or other contaminants that will clump media or clog filters.
4.2.3 When blasting small parts or objects having
small pieces that could become dislodged and fall off,
BNP 65P and 220P PRESSURE BLAST CABINETS Page 12
place an appropriately-sized screen over the grate (or under the grate when frequently blasting small parts) to prevent parts from falling into the hopper.
4.2.4 Close door; the door interlock system will
prevent blasting if either door is open.
4.3 Blasting Operation
CAUTION
Always close cabinet, reclaimer and dust
collector doors before blasting. Keep all doors closed during blasting.
Always wear blast gloves. Avoid pointing the blast nozzle toward the
view window.
Use the blow-off nozzle to blow media off
parts before opening doors.
After blasting, keep doors closed and
exhauster running until the cabinet is clear of all airborne dust.
Stop blasting immediately if dust leaks are
detected.
4.3.1 Slowly open the air valve on the air supply hose
to the blast machine. Check for air leaks on the initial start up and periodically thereafter.
4.3.2 Turn ON the lights and exhauster. The on/off
switch performs both functions.
4.3.3 Load parts.
4.3.4 Close door; the door interlock system will
prevent blasting if either door is open.
WARNING
Shut down the cabinet immediately if dust leaks from the dust collector or cabinet. Make sure the dust collector filters a re correctly seated and not worn or damaged. Prolonged breathing of any dust could result in serious lung disease or death. Short term ingestion of toxic dust such as lead, poses an immediate danger to health. Toxicity and health risk vary with dust generated by blasting. Identify all material being removed by blasting, and obtain Safety Data Sheets (SDS) for the media.
4.3.5 Insert hands into rubber gloves.
4.3.6 To blast, hold the nozzle holder or hose just
behind the nozzle holder, point the nozzle toward the object to be blasted, and apply pressure to the foot pedal. Blasting will begin almost immediately.
4.3.7 Adjust the pilot pressure regulator to the
required blasting pressure, per Section 5.1. The regulator is located on the top, left side of the cabinet.
NOTE: Pressure registers on the gauge only while blasting.
NOTE When blasting parts off the grate, use a solid conductive back rest to support the part. Without this assist, especially with longer blasting operations, the operator will tire easily from resisting blast pressure, and static electricity could build up in the ungrounded part and cause static shocks. Whenever possible avoid holding small parts that require blasting into the glove.
4.3.8 If an object should fall through the grate, stop
blasting immediately and retrieve it.
4.4 Stop Blasting
4.4.1 To stop blasting, remove pressure from the foot
pedal. The blast machine will depressurize each time the foot pedal is released.
4.4.2 The blast machine refills with media stored in
the reclaimer each time the foot pedal is released. Refilling takes approximately 15 seconds.
4.4.3 Use the blow-off nozzle to blow media off
cleaned parts.
4.4.4 Keep doors closed and exhauster running until
the cabinet is clear of all airborne dust.
4.4.5 Unload parts. Shut off the air supply valve, and
switch OFF the lights and exhauster.
4.5 Blasting Technique
4.5.1 Blasting technique is similar to spray painting
technique. Smooth continuous strokes are most effective. The distance from the part affects size of blast pattern. Under normal conditions, hold the nozzle
approximately 6" from the surface of the part.

5.0 ADJUSTMENTS
5.1 Blasting Pressure
5.1.1 The pilot pressure regulator, located on the top,
left side of the cabinet, enables the user to adjust blasting pressure to suit the application. The suitable pressure for most purposes is about 80 psi. Lower pressures may be required on delicate substrates, and will reduce media breakdown. Higher pressure may be required for difficult blasting jobs on durable substrates, but will increase media breakdown. Optimal production can only be achieved when pressure is carefully monitored.
5.1.2 If the application requires blasting below 40 psi,
first pressurize the blast machine at 40 psi, and then turn the pressure to the required setting before blasting the part. If the initial pressure is below 40 psi, the pop-up valve may not seal.
5.1.3 Pressure registers on the gauge only while
blasting. While holding the nozzle securely, adjust air pressure at the pilot regulator located on the top, left side of the cabinet.
5.1.4 To adjust pressure, unlock the knob by pulling it
out as shown in Figure 13, and turn it clockwise to increase pressure or counter-clockwise to decrease pressure. Once operating pressure is set, push in on the knob to lock it and maintain the setting.

5.2.1 Adjust media flow using the metering valve
located at the bottom of the blast machine. The valve is closed when the handle is fully to the right. To adjust, begin with the valve closed, press the foot pedal and have someone slowly move the handle to the left to increase media flow. Allow time for the flow to stabilize before further adjusting. The valve is fully open when the handle is at the full left position. The optimum flow rate depends on the type and size of media and blasting pressure, and can best be determined by experience. Use as little media as possible to do the job while maintaining the best cleaning rate. Generally, with the correct mixture, abrasive can be seen as light discoloration as it exits the nozzle.

5.3 Reclaimer Static Pressure
5.3.1 Correct static pressure varies with the size of
reclaimer and the size, weight and type of media.
5.3.2 Adjust static pressure by opening (handle inline
with air flow) or closing (handle perpendicular to air flow) the dust collector damper. Refer to the dust collector owner’s manual, the damper is located on the inlet on CDC-1 dust collectors, and on the exhauster outlet RPC­2 and RPH dust collectors. If the damper is not opened far enough, the reclaimer will not remove fines, resulting in dusty media, poor visibility, and possible media blockage in the conveying hose. If the damper is opened too far, it may cause carryover (usable media carried into the dust collector) and result in excessive media consumption. Open only as far as necessary to obtain a balance of dust removal without media carryover.
5.3.3 A manometer is useful when adjusting or
monitoring static pressure. The optional manometer kit is listed under Optional Accessories in Section 9.1. Refer to Section 5.7 for operation. The following are
BNP 65P and 220P PRESSURE BLAST CABINETS Page 14
static pressure starting points for given media. Static pressure may need to be lower with finer media and higher with coarser media. Run the media through several blast cycles allowing the reclaimer to function with these settings. Inspect the media in the reclaimer and fines in the dust collector as noted in Paragraph
5.3.2. Continue adjusting static pressure until optimum media cleaning without carryover is attained.
Glass Bead No. 4 to 7 ................................. 3" to 3-1/2"
Glass Bead No. 8 to 13 ................................... 2-1/2 - 3"
Alox. 60 & coarser ................................................ 4 - 5"
Alox. 80 & finer ............................................... 2-1/2 - 3"
Steel Grit .............................................................. 6 - 7"
5.3.4 If the damper has been adjusted and carryover
or excessive dust in the media continues, the optional adjustable vortex cylinder may help by fine-tuning media separation. The vortex cylinder is usually required only when using 180-mesh and finer media, or lightweight media. Refer to Section 5.4, and Accessories in Section 9.1.
5.4 Optional Externally-Adjustable Vortex Cylinder
NOTE: The externally adjustable vortex is an option when the cabinet is provided with a CDC-1 Dust collector. The vortex is standard with reclaimers when the cabinet is provided from the factory with an RPC or RPH dust collector.
The vortex cylinder fine-tunes media separation. Before adjusting the cylinder, adjust the damper on the dust collector to increase or decrease static pressure per Section 5.4. Once the damper is adjusted, adjust the cylinder.
5.4.1 The vortex cylinder is located atop the reclaimer
where the flex hose connects. Adjustments are made by loosening the handle's tensioning knob and moving the handle to achieve the correct setting. When the correct setting is established, tighten the locking knob to prevent movement. Start with the lever slightly to the right (about one o’clock as shown in Figure 15) of the vertical position.
5.4.2 To Remove More Fines: (Too much dust in
media) Raise the cylinder by moving the lever left toward "COARSE", in 1/4" increments at the indicator plate. Allow the media to go through several blast cycles before determining if further adjustment is needed.
5.4.3 To Remove Less Fines: (Excessive usable
media is carried to the dust collector) Lower the vortex cylinder by moving the lever right toward "FINE", in 1/4" increments at the indicator plate. NOTE: If the cylinder is lowered too far, the reclaimer will again begin to allow usable media to be carried over, and cause abnormally high static pressure.

5.4.4 When using media finer than 180-mesh, the
inlet baffle of the reclaimer may need to be removed. Refer to Section 1.10.6.

5.5 Door Interlocks, Figure 16
WARNING
Never attempt to override the interlock system. Doing so could result in injury from unexpected blasting.
5.5.1 The door interlocks disable the blasting
control circuit when either door is open. To enable blasting, the door interlock switch must be engaged when the doors are closed. The interlocks are set at the factory and do not normally require field adjustment unless parts are replaced. When adjustment is required, proceed as follows.
5.5.2 Close cabinet doors.
5.5.3 Loosen the actuator bracket screws and
adjusting screw nut. Move the actuator bracket up or down, and the screw sideways, to center the screw on the over-travel stop. Tighten the bracket screws.
5.5.4 Turn the adjusting screw in or out as required to
engage the switch without applying excessive pressure on it. Tighten the adjusting screw nuts.
5.5.5 Test the operation with the doors open and then
again closed. Point the nozzle away from the door during the tests, and open the door only enough to disengage the interlock switch. The interlocks should stop the blasting when the doors are opened, and permit blasting when the doors are closed. NOTE: Negative pressure inside the cabinet may cause the doors to flex inward. Tests should be performed with the exhauster running.

5.6 Cabinet Air-Inlet Damper (cabinet static pressure)
5.6.1 Once the inlet is initially set per Section 2.13, it
seldom requires readjustment. The initial setting produces approximately 0.5" to 0.75" of static pressure
in the cabinet enclosure Do not confuse cabinet static
pressure with reclaimer static pressure, which is controlled by the dust collector damper as noted in Section 5.3. Reclaimer pressure must be set before cabinet pressure.
5.6.2 Using a manometer (as noted in Section 5.7 and
listed in Section 9.1) is the most accurate method of monitoring and adjusting cabinet pressure. Following the instructions packed with the manometer, start the exhauster and insert the needle into a glove, and adjust pressure using the inlet damper. Open the damper farther to decrease static pressure or close it farther to increase pressure.
5.6.3 If a manometer is not available, use the gloves
as an indicator. With the exhauster running, the gloves should be inflated, but not elevated off the grate.
5.7 Optional Manometer
NOTE: These instructions show several methods of taking static pressure readings (negative pressure) on cabinet reclaimers using a flexible tube manometer. Use the method best suited for the application. The instruction explains the processes for taking periodic readings and shows how to permanently install the manometer for taking frequent readings. Permanent fittings should be installed when rigid ducting is used, or when the manometer installation is permanent. Use silicone sealer or other sealant to seal around the fitting to prevent leaks. The fitting should be capable of being capped when the manometer tube is removed. Capping the fitting will prevent leaks that alter the reclaimer’s separation efficiency. The readings are reference points so it doesn’t matter where the readings are taken as long as they are always taken at the same location. Taking readings at different locations could produce different results. Static pressure readings at the door are generally 0.5" to 1" lower than those taken above the reclaimer.
5.7.1 Refer to directions packed with the manometer
for preparation and operating instructions for the manometer.
5.7.2 Connect one end of the 3/16" ID tubing to one of
the tubing connectors (elbow) at the top of the manometer by pushing it over the barbed adaptor.
5.7.3 Leave the needle protector on the needle and
insert the needle into the other end of the tubing. The ends of the tubing must fit tight on the manometer and needle; leaks will give inaccurate readings.
5.7.4 Open both manometer valves (elbows) per the
instructions provided with the manometer.
5.7.5 Magnets on the manometer hold it in position on
the reclaimer body. The manometer must be vertically­plumb so the fluid is level on both sides.
5.7.6 Adjust the slide rule to align the zero with the
fluid level. Refer to Figure 18
5.7.7 Needle placement: Ref. Figure 17.
5.7.7.1 Taking readings in the flex hose: Remove the
needle protector, and insert the needle into the flex hose approximately 8" from the top of the reclaimer.
5.7.7.2 Taking readings at the reclaimer door: Open
the reclaimer fill door, remove the needle protector and place the needle so the point is inside the door opening. Carefully close the door on the needle. The side of the needle will embed into the rubber, creating an airtight seal.

BNP 65P and 220P PRESSURE BLAST CABINETS Page 16
Pull-thru reclaimers only. Insert the needle into straight section of flex hose, about 8-inches above the top of the reclaimer.
Place the needle so the point is inside the door opening. Carefully close the door on the needle.
For taking frequent readings, install a permanent fitting in the reclaimer wall, just below the inner cone as shown.
8
The manometer must be vertical when
taking pressure readings.
With the exhauster OFF, slide the rule to align the
zero with the fluid level.
To obtain the pressure reading: With the exhauster ON, add the number of inches the fluid travels up one column, to the inches the fluid travels down the other column. The total is the static pressure reading.
Reclaimers are for reference and may differ from those shown.
Figure 17
In the example shown, fluid traveled up
the right column 1-3/4 inch,
and down the left column 1-3/4 inch.
Static pressure is determined by adding
the columns together. In the example,
the static pressure is 3-1/2 inches.
5.7.8 Turn the exhauster ON. The negative (static)
pressure will move fluid in the tube.
NOTE: Readings must be taken with the cabinet doors open, and with the exhauster running.
5.7.9 To find the static pressure, add the number of
inches the fluid travels up one column to the inches the fluid travels down the other column. Refer to the example in Figure 18.
5.7.10 After the readings are taken, replace the needle
protector. Close the manometer valves and store the manometer in the original container in a clean area. NOTE: If the manometer installation is permanent, the manometer may remain on the reclaimer body after the

6.0 PREVENTIVE MAINTENANCE
NOTE: To avoid unscheduled downtime, establish an inspection schedule. Inspect all parts subjected to media contact, including; nozzle, media hose, flex hose, in addition to all items covered in this section. Adjust frequency of inspections as needed based on usage, type of media, and condition of parts being blasted.
6.1 Daily
6.1.1 Check media level in reclaimer and refill as
necessary.
6.1.2 Check reclaimer debris screen for debris. The
screen is accessible through the reclaimer door. With the exhauster OFF, remove the screen and empty it daily or when loading media. Empty the screen more often if part blasted causes excessive debris. Do not operate the machine without the screen in place, oversized byproduct from blasting could plug the nozzle.
6.1.3 Empty the compressed-air filter drain pail at
least once a day, and more often if needed. Moist air inhibits the flow of media. Drain the air line and receiver tank regularly. If the filter does not remove enough moisture to keep media dry and flowing, it may be necessary to install an air dryer or aftercooler in the compressed-air supply line.
6.1.4 Refer to the dust collector owner’s manual and
empty dust containers. Adjust intervals based on filling rate.
6.1.5 Refer to the dust collector owner’s manual and
drain the pulse manifold at the end of each shift.
6.1.6 Refer to the CDC-1 dust collector manual for
pulsing instructions and pulse the cartridge at least every half hour of blasting and before turning OFF the exhauster. Dusty blasting conditions will require more frequent pulsing. RPC and RPH dust collectors are automatically pulsed at timed intervals.
6.2 Weekly
6.2.1 Make sure that couplings are secure and lock
pins and safety cables are in place.
6.2.2 Check coupling gaskets, couplings, and nozzle
holders for leaks and wear. Replace as necessary.
6.2.3 Inspect nozzle for wear. Replace when orifice
diameter is worn 1/16” larger than original size. Replace
the nozzle washer when worn.
6.2.4 While blasting have someone inspect all
external piping, hoses, valves, and couplings for air leaks. If leaks are found repair immediately.
6.2.5 While blasting have someone check the blast
machine for air leaks. If leaks are found around the pop­up valve, inspection door, or pipe fittings at the bottom of the cone, stop blasting immediately and repair or replace worn parts. If leaks are not identified and corrected, abrasive erosion could cause irreparable damage to the blast machine.
6.2.6 Inspect the blast hose for wear and thin spots by
pinching it every 6 to 12 inches. Soft spots mean the hose is worn. The first sign of wear is usually along the outside radius where the hose bend just behind the nozzle holder. Replace the hose as soon as soft spots
are noted. Couplings will not safely grip worn hose,
and may detach under pressure.
6.2.7 Inspect gloves for wear. The first sign of
deterioration may be excessive static shocks. Replace as needed per Section 7.1.
6.2.8 Inspect flex hoses for wear.
6.2.9 Inspect outlet valve diaphragm: Remove the cap
four screws and inspect the diaphragm. Replace the diaphragm if worn or cracked. Continued use with a warn diaphragm will quickly wear the valve casting.
6.2.10 Inspect view window cover lens, Replace as
needed per Section 7.2.
6.2.11 During operation, inspect cabinet door seals for
media leaks.
6.3 Monthly
6.3.1 Inspect reclaimer wear plate or rubber liners for
wear. Replace as necessary per section 7.10 or 7.11.
6.3.2 Inspect reclaimer door gasket for damage.
6.4 Dust Collector
Reverse-pulse dust collectors are covered in a separate manual. Refer to Section 1.1.1.

7.0 SERVICE MAINTENANCE
7.1 Gloves
7.1.1 Special static-dissipating gloves are provided for
operator comfort. It will be necessary to change gloves periodically as they wear. The first sign of deterioration may be excessive static shocks.
7.1.2 Band-clamp type: Band-clamp type gloves are
held in place by metal band-clamps on the inside of the cabinet. To replace, loosen the clamps with a screwdriver, replace the gloves, and tighten the clamps.
7.1.3 Quick-Change type, clampless installation:
Quick-change gloves are held in place using spring rings sewn into to the attachment end of the glove. To install, insert the glove into the arm port, so one spring is on the inside of the port and the other is on the outside, sandwiching the arm port between both spring rings.
7.2 View Window Cover Lens
7.2.1 Rapid frosting of the view window can be
avoided by directing ricocheting media away from the window, and by installing a cover lens on the inside surface of the window. Using cover lenses prolongs the life of the view window.
Coupling Screws
7.2.2 The best way to install a cover lens is to remove
the window from the cabinet. If, for some reason, it is not practical to remove the window, the lens may be applied with the window glass in place.
7.2.3 To install a cover lens, carefully remove the
adhesive backing making sure the adhesive remains on the lens, and apply the lens to the clean, dry, inner surface of the view window. When the cover lens becomes pitted or frosted, replace it.
7.3 Blast Hose and Nozzle, Refer to Figure 19
7.3.1 When replacing blast hose make sure the hose
is square cut and that it is fully inserted into the nozzle holder and coupling until it seats tightly against the shoulder in the holder and coupling, as shown in Figure
19. Make sure correctly sized screws are used to secure the nozzle holder and blast hose coupling. Screws should not penetrate the inside of the blast hose.
7.3.2 Replace the nozzle when its inside diameter has
increased by 1/16", or sooner if pressure diminishes noticeably. Make sure the nozzle washer is in good condition and in place before screwing the nozzle into the nozzle holder. Make sure the nozzle is screwed tightly into the nozzle holder; if nozzle is not tight against the nozzle washer, thread erosion will occur and nozzle will fuse to nozzle holder.

7.9.2 Remove the old seat by using a finger,
screwdriver, or similar object, to work the seat out of the retainer groove.
7.9.3 Push the new seat all the way through the port
and then fit it into the groove. For the last few inches, pull up on the seat and allow it to "pop" into position.
7.10 Reclaimer Wear Plate Replacement
7.10.1 Remove the reclaimer inlet adaptor and old
wear plate. The wear plate is held in place with screws attached from the outside of the reclaimer; remove the screws and pull out the wear plate from the reclaimer inlet.
7.10.2 Angle the new wear plate into reclaimer inlet
until it is in position with the straight end at the inlet. Using a board or similar object as leverage, pry the wear plate against the inner wall of the reclaimer. While forcing the wear plate against the reclaimer, install sheet metal screws through the old screw holes to secure. Caulk seems between the wear plate and reclaimer to prevent rapid wear in those areas.
7.11 Replacing or Field Installing Optional Reclaimer Rubber Liners, Figure 25. The reclaimer
must be designed to accept liners and have a removable top.
7.11.1 Remove the flex hoses from the reclaimer inlet
and outlet.
7.11.2 Remove the bolts and nuts, securing the
reclaimer top, and then remove the top.
7.11.3 If the reclaimer is currently unlined, proceed to
the installation note preceding Paragraph 7.11.10.
7.11.4 Remove the top liner and tube liner. NOTE: 900

Reverse-pulse dust collectors are covered in a separate manual.
8.0 TROUBLESHOOTING
WARNING
To avoid serious injury, observe the following when troubleshooting. Turn OFF compressed air, and lockout and
tagout the air supply.
If checking the controls requires air, always
enlist the aid of another person to:
Hold the nozzle securely.
Operate the foot pedal.
Never bypass the foot pedal or wedge it in
the operating position.
Never override the door interlock system.
8.1 Poor visibility
8.1.1 Dirty filter cartridge(s). Pulse cartridge and
empty dust container regularly. When using an RPC or RPH, refer to the reverse-pulse dust collector manual to adjust pulse pressure and pulse sequence.
8.1.2 Exhauster motor not operating. Check voltage to
motor and motor wiring.
8.1.3 Check rotation of exhauster motor; the motor
should rotate as indicated by the arrow on the housing.
If it does not rotate in the proper direction, lockout and tagout electrical power and switch the motor leads as
shown on the motor plate. Refer to Section 2.11.
8.1.4 Using friable media that rapidly breaks down, or
using media that is too fine or worn out.
8.1.5 Dust collector damper closed too far restricting
air movement through the cabinet. Adjust static pressure per Section 5.3.
8.1.6 Cabinet air-inlet damper closed too far restricting
air movement through the cabinet. Adjust damper per Section 2.13 and 5.6.
8.1.7 Reclaimer door open.
8.1.8 Hole worn in flex hose between cabinet hopper
and reclaimer inlet or between the reclaimer and dust collector. Replace hose and route it with as few bends
as possible to prevent wear.
8.1.9 Obstruction in flex hose between the cabinet hopper and reclaimer inlet.
8.1.10 Nozzle worn. Replace the nozzle when its orifice
diameter has increased by 1/16".
8.2 Abnormally high media consumption
8.2.1 Door on reclaimer open or worn door gasket. Air
entering reclaimer around the door will cause media carryover to the dust collector. DO NOT operate unless all doors are closed.
8.2.2 Dust collector damper open too far. Adjust static
pressure per Section 5.3.
8.2.3 Media may be too fine or worn-out.
8.2.4 Using friable media that rapidly breaks down.
8.2.5 Blast pressure too high for the media, causing media to break down.
8.2.6 Hole worn in reclaimer, or leak in reclaimer
seams. Check entire reclaimer for negative-pressure leaks.
8.2.7 Outlet valve not sealing. Inspect diaphragm.
8.2.8 Metering valve requires adjustment. Adjust
media flow per Section 5.2.
8.2.9 When using media finer than 180-mesh, the
reclaimer inlet baffle may need to be removed. Refer to Section 1.10.6.

8.3 Reduction in blast cleaning rate
8.3.1 Low media level. Check media level and refill if
low.
8.3.2 Media/air mixture out of adjustment. Adjust per
Section 5.2.
8.3.3 Reduced air pressure. This may be caused by a
malfunctioning regulator, a dirty filter element in air filter, partially-closed air valve, leaking air line, or other air tools in use.
8.3.4 Blockage in nozzle. Blockage may occur as a
result of a missing debris screen.
8.3.5 Moist media. Frequent bridging or blockage in
the area of the metering valve can be caused by moisture. See Section 8.5.
8.3.6 Air leaking through the outlet valve, reducing
blast pressure and control pressure to media metering valve. Inspect diaphragm and outlet valve body.
8.4 Plugged nozzle
8.4.1 A damaged or missing reclaimer screen will
allow large particles to pass and block the nozzle. Replace or re-install as necessary.
8.5 Media bridging
8.5.1 Frequent bridging or blockage in the media
metering valve can be caused by damp media. Media becomes damp by blasting parts that are slightly oily, from moisture in the compressed-air line, or from absorption from ambient air.
8.5.2 To avoid contaminating media from the
workpiece, all parts put into the cabinet should be clean and dry. If parts are oily or greasy, degrease and dry them prior to blasting.
8.5.3 Moist compressed air may be due to a faulty
compressor that overheats, or pumps oil or moisture into the air line, too long an air line permitting moisture to condense on the inside, and from high humidity. Drain filters and receiver tank regularly. Ongoing problems with moist air may require the installation of an air dryer or aftercooler in the air supply line.
8.5.4 Absorption. Some media types tend to absorb
moisture from the air, especially fine-mesh media in areas of high humidity. Empty the media and store it in an airtight container when cabinet is not in use.
8.5.5 A vibrator mounted either on the blast machine
leg or on a bolt on the media metering valve may help to prevent bridging of fine-mesh media. NOTE: To avoid the possibility of compressing media, a vibrator should be setup to start only when the foot pedal is pressed.
8.6 Neither media nor air comes out the nozzle when the foot pedal is pressed
8.6.1 Depressurize the blast machine, and check the
nozzle to see if it is plugged. See Section 8.4.
8.6.2 Make sure the blast machine pressurizes when
the foot pedal is pressed. If it does not pressurize, refer to Section 8.7.
8.6.3 Make sure the media metering valve and the
choke valve are open.
8.7 Blast machine does not pressurize
8.7.1 Make sure the air compressor is operating and
air supply valves are open.
8.7.2 Make sure the pressure regulator is not set too
low of OFF. Minimum pressure is 40 psi. See Section
5.1.
8.7.3 Door interlocks not engaging. Check door
interlock adjustment per Section 5.5.
8.7.4 Inadequate air supply. Refer to the cfm air
consumption table in Figure 4.
8.7.5 Inspect diaphragm in the outlet valve for wear.
8.7.6 Inspect pop-up valve and seat for wear and
alignment.
8.7.7 Blocked or leaking control line. Check all fittings
and urethane tubing for blockage or leaks.
8.7.8 Foot pedal valve malfunction. Check foot pedal
for alignment, and inlet and outlet lines for pressure.
8.7.9 Make sure the lines are not reversed on the foot
pedal or pilot regulator. Refer to the schematic in Figure 5.
8.7.10 Check the 4-way valve per Paragraphs 8.11.5
and 8.11.6.
8. 7.11 Inspect the check valve for obstruction or broken flap.

8.8 Blast machine does not depressurize or depressurizes too slowly
8.8.1 Check for blockage in the 4-way valve mufflers.
8.8.2 Make sure the 3-way valve in the foot pedal
exhausts air when the pedal is released. If it does not exhaust, check the inbound air line for blockage, if no blockage, replace the valve.
8.8.3 Inspect brass control-line filter attached to
diaphragm outlet valve for media blockage. If media is present, inspect outlet valve diaphragm for damage.
8.8.4 Check the outlet muffler that is located inside
the cabinet, for blockage.
8.8.5 Check 4-way air valve for jamming per
Paragraphs 8.11.5 and 8.11.6.
8.9 Heavy media flow
8.9.1 Make sure the choke valve is open.
8.9.2 Media metering valve open too far. Adjust per
Section 5.2. If adjusting the media valve does not regulate media flow, empty the machine, depressurize the machine, and inspect the internal parts of the valve for wear.
8.10 Media surge: A small amount of surge is
normal at start-up.
8.10.1 Heavy media flow. Adjust per Section 5.2
8.10.2 Empty the blast machine, depressurize the blast
machine, and inspect the internal parts of the metering valve for wear. Refer to the Sentinel Media Metering Valve manual number 20951.
8.11 Air only (no media) comes out the nozzle
8.11.1 Make sure the machine contains media.
8.11.2 Make sure the media metering valve is not
closed. Adjust media flow per Section 5.2.
8.11.3 Make sure the media metering valve opens
when foot pedal is pressed. Refer to the metering valve owner’s manual.
8.11.4 Check for minor blockage in the media metering
valve by fully opening the metering valve, and closing the choke valve. Activate the foot pedal to blow out obstructions. If this procedure fails, depressurize the machine, open the metering valve clean out cap and check for foreign objects.
© 2016 CLEMCO INDUSTRIES CORP. www.clemcoindustries.com Manual No. 21278, Rev. H, 08/16
8.11.5 Check the muffler on the 4-way air valve. Air
should exhaust from the muffler when the foot pedal is pressed. If air does not exhaust, remove the muffler and try again. If air exhausts now, the muffler is blocked. If air still does not exhaust, the 4-way valve may be faulty, refer to Paragraph 8.10.6 to check the 4-way valve.
8.11.6 Check the 4-way valve as follows: Depressurize
the air supply line. Remove the tubing leading to either the media metering valve or diaphragm outlet valve. Pressurize the air supply line. No air should exhaust from the tube adaptor. Press the foot pedal, air should start exhausting at the adaptor, and stop when pressure on the pedal is released. If it does not operate accordingly, the 4-way valve is faulty or air supply is insufficient.
8.11.7 Outlet valve not sealing. Inspect diaphragm
8.11.8 Metering valve requires service. Refer to the
media metering valve manual.
8.12 Media buildup in cabinet hopper, does not convey to reclaimer
NOTE: Do not pour media directly into the cabinet hopper, as overfilling may occur. Overfilling will result
in media carryover to the dust collector and possible blockage in the conveying hose.
8.12.1 Exhauster motor rotating backwards. The motor
should rotate as indicated by the arrow on the exhauster housing. If it does not rotate in the proper direction,
lockout and tagout electrical power and switch the
motor leads as shown on the motor plate. Refer to the system’s wiring schematic. Refer to Sections 2.11.
8.12.2 Dust collector damper closed too far restricting
air movement through cabinet. Adjust static pressure per Section 5.3.
8.12.3 Dust collector filter cartridge(s) clogged. Refer to
the dust collector owner’s manual.
8.12.4 Hole worn in flex hose between cabinet hopper
and reclaimer inlet or between the reclaimer outlet and dust collector inlet. Replace hoses and route them with as few bends as possible to prevent wear.
8.12.5 Reclaimer door open. DO NOT operate unless
door is closed.
8.12.6 Obstruction in flex hose. Remove hoses and
check for blockage.
BNP 65P and 220P PRESSURE BLAST CABINETS Page 26
8.13 Static shocks
8.13.1 Cabinet and/or operator not grounded. Abrasive
blasting creates static electricity. The cabinet must be grounded to prevent static build-up. See Sections 2.10 and 2.4.1. If shocks persist, the operator may be building up static. Attach a small ground wire, such as a wrist strap, from the operator to the cabinet.
8.13.2 Gloves wearing thin. Inspect gloves and replace
them as needed.
8.13.3 Avoid holding parts off the grate. Static will
build-up in the part if not dissipated through the metal cabinet.
8.14 Dust leaking from cabinet
8.14.1 Refer to Section 8.12.
8.15 Dust leaking from dust collector
