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.

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.

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.

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

Figure 3

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.

BNP 65P and 220P PRESSURE BLAST CABINETS Page 6

900 cfm: 2 HP, 208/230/460V, 3-PH, 60 HZ Supplied with 230-volt control panel unless 460-volt is

specified at the time the order is placed. FLA 208/5.5, 230/5.6, 460/2.8.

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

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.

2.11.2 Three-Phase Wiring

NOTE: a wiring schematic is packed inside the cabinet’s control panel. After wiring is completed, keep a copy of the schematic with the manual for future reference and for electrical replacement parts.

2.11.2.1 Refer to the wiring schematic stowed inside the

control panel mounted on the cabinet and wire from the users disconnect to the panel and from the panel to the dust collector motor, per instruction on the motor dataplate.

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

3.4.1 Assemble the armrest and mounting brackets as

shown in Figure 9.

3.4.2 Position the assembly so the armrest is about

even with the bottom of the arm-port opening. Mark one hole location on the front of the cabinet at each mounting bracket.

3.4.3 Drill a 3/8" hole at both locations and mount the

armrest using 5/16 cap screw, washers and nuts. Install the bolts from inside the cabinet to protect the threads from abrasion, should the armrest need to be removed at a later date.
