Page 17
4.2. Installing the Filter Shroud (XFC 225 and XFC 1000 only)
The cloth filter shroud is mounted to a ring on the underside of the filter chamber stand. It reduces housekeeping duties around the filter chamber by preventing dust from becoming airborne when dust and fines are discharged from the filter chamber. The dust container below the shroud is customer-supplied—the standard 24” (610 mm) clearance stand is designed for use with a 5-gallon (19 liter) pail, and the optional 38” (960 mm) clearance stand is designed for use with a 55-gallon (208 liter) drum.
Use the following procedure to install the filter shroud:
1. Insert the filter shroud support wire into the slotted hole in the middle of the cloth
filter shroud. Use supplied hardware to secure.
2. Slip the filter shroud over the retaining ring located on the bottom side of the filter
stand mounting plate. Secure it with the worm clamp provided.
3. Place the dust container below the filter chamber stand and insert the filter shroud.
Secure the filter shroud to the dust container:
For 5-gallon dust containers, the filter shroud will need to be trimmed and fastened to the top lip of the can with a band clamp.
For 55-gallon drums, do not trim the filter shroud. Secure the drawstring on the shroud around the drum, making sure the open end of the shroud hangs freely inside the drum.
4. Make sure the operation of the counterweighted flapper dump valve is not obstructed
in any way by the filter shroud.
Do not obstruct the filter shroud in any way. Empty the dust container before the dust level obstructs the end of the filter shroud. Failure to follow these warnings may result in reduced filtering efficiency and contaminants entering the conveying system.

Page 20
4.3.3. XFC-S, XFC 225, XFC 1000
The XFC 225 and XFC 1000 safety filters feature compressed air blowback. The XFC-S safety filter is available with either compressed air blowback or implosion blowback. The blowback solenoids are controlled by either distributed or local I/O central conveying controllers. An integrated blowback controller is available for compressed air models. Electrical connections vary depending on the type of blowback and controller:
Local I/O Control. (Compressed air or implosion blowback) The solenoid is pre-wired. Attach the solenoid wire to the termination point in the central conveying controller. Refer to the manual and drawings that are provided with the conveying control for the location of the blowback solenoids.
Distributed I/O Control. (Compressed Air or implosion blowback) The solenoid is prewired with a patchcord that will plug into the ArmorBlock module. Refer to the installation drawing provided with the unit.
Integrated Control. (Compressed air blowback only) The solenoid is pre-wired. Choose a location for the blowback controller, and terminate the wires in the controller using the blowback control drawings that are included with the unit.
4.4. Compressed Air Blowback Connection
To provide proper filter element cleaning, the compressed air supply must be regulated to 80 PSI (5.5 bars). Low air pressure will cause poor filter element cleaning. Air consumption depends on the frequency and length of cleaning air pulses into the filter element.
Connect a minimum of 3/8” (9 mm) air line to the top of the solenoid valve air block. Compressed air must be clean, dry, and free of oil. A filter regulator and shut-off are recommended components of your in-plant air supply. In-line filters can handle small amounts of moisture; in-line desiccant filters or packed beds of granular absorbing polymer can remove oil mist and condensed oil.
You may need to install an accumulator in your air supply system to enhance blowback effectiveness if your system cannot consistently meet these requirements. Make sure you use full­sized 3/8” or larger diameter pipe or tubing when making the connection.
19
Page 21
4.5. Implosion Blowback Connection
The clearing valve (implosion blowback valve) is located on the outlet of the vacuum filter. Connect the clearing valve to a 60-80 PSI (4.1-5.5 Bar) compressed air supply. Compressed air must be clean, dry and free of oil.
Run a 3/8” (9 mm) branch line to supply the vacuum hoppers in your system. Install a 3/8” (9 mm) x 1/8” (3 mm) tee valve in the up position near the filter chamber.
Connect shop compressed air to port number 3 on the clearing valve solenoid with 1/4” (approx. 6 mm) poly tubing. Connect port number 2 to the clearing valve. Port 1 is to be exhausted to the atmosphere. (See Figure 2).
The 3/8” (9 mm) branch supply line should include a shut-off valve for on/off control, an air filter/pressure regulator with a gauge for pressure control, and mini-lubricators located at each vacuum receiver. Install a quick-disconnect fitting or a shut-off valve in the compressed air piping leading to the vacuum receiver’s clearing valve to speed receiver cover removal for cleanout or service.
Note: XFC-A style filters also include a sealing valve mounted to the inlet of the filter chamber. This valve is pre-piped to the main solenoid.

5. Functional Description
This functional description is intended for all operating personnel of the equipment.
General knowledge of conveying systems is required to operate the equipment
Ensure in each case that the operating personnel are sufficiently knowledgeable about the equipment.
The safety filter is used to clean the vacuum air of the entire system and must be installed in every central conveying system to protect the vacuum pump from dust and debris. Primary system filtration occurs in the filter chamber, not in the vacuum receivers. The central filter chamber reduces maintenance of vacuum receiver filters on top of processing machines.
A filter cartridge inside the safety filter separates the vacuum air from the dust particles flowing along with it. A vortex created in the filter chamber separates carry-over from the air stream, and the filter element catches any dust and debris drawn into the upper chamber.
Depending on the style of filter, the filter cartridge is cleaned via implosion blowback or compressed air blowback. Dust and debris settles in the collection bin, which must be emptied periodically. No materials are conveyed during blowback. The blowback cycle is adjustable. (Refer to the Conveying Control Manual)
Compressed Air Blowback. Compressed air blowback is accomplished when short blasts of compressed air are blown through the filter.
Implosion Cleaning. Implosion cleaning is accomplished by using an clearing valve to create a vacuum in the collection area of the filter chamber. The clearing valve is actuated and allows an inrush of atmospheric air, which flows through the filter cartridge and cleans it from the inside out.
The XFC-SC Cyclonic Pre-Filter is also available. Consult factory.

6. Operation
Before operating the central safety filters, make sure all mechanical installations are
complete.
Make sure all electrical and compressed air connections are complete and correct.
Make sure that no leaks are present in the filter chamber housing. Check clamps for proper adjustment.
6.1. Adjusting the Blowback Air Pulse Timing
The length of the air pulses and the time between air pulses require adjusting to match up with dusting characteristics of the material being conveyed. If more dusting occurs, then quicker and more frequent compressed air pulses are required to clean the filter element.
Central Conveying Control. To adjust the blowback air pulse timing, refer to the manual for the central conveying controller.
Compressed Air Blowback with Integrated Control. Locate the timer inside the control enclosure on the circuit board. With the unit operating, turn the potentiometer counterclockwise to speed up the timing (shortening the air pulse duration and time between air pulses); turn clockwise to slow down the timing (lengthening the air pulse duration and time between air pulses).
23
Page 25
6.2. Adjusting the Number of Air Pulses
The number of air pulses during blowback can be adjusted as necessary to effectively clean the filter element.
Central Conveying Control. To adjust the number of air pulses, refer to the manual for the central conveying controller.
Compressed Air Blowback with Integrated Control. Locate the DIP switch inside the blowback control box. Set the DIP switch to the number of pulses you want from 1 to 16, using the DIP switch settings shown in Figure 3. The diagram is also shown on the blowback control box electrical schematic located in your customer service packet.

10. Troubleshooting
Problem Possible Cause Solution
High-vacuum alarm Filter element dirty. Clean or replace filter
Filter element is becoming obstructed too frequently by fines and dust
Vacuum conveying rate is declining due to a vacuum loss in the system.
Dump delay time set to zero, or insufficient dump delay time.
Dusty material. Consult sales representative.
Dusty material—optional compressed air filter cleaning may be needed on filter chamber.
Pump package blower problem. Use a cfm/cfh monitoring device to ensure that blower cfm/cfh is to the manufacturer’s specifications.
Set dump delay time to the time it takes the largest vacuum hopper in the system to dump.
Consult sales representative
Filter chamber problem. The vacuum at the filter chamber should be the same as the blower generates. If the vacuum at the filter chamber is adequate, the problem is down line.
Dirty filter. Clean or replace filter:
Loose clamps, gaskets, or couplers. Tighten or replace.
Filter chamber discharge flapper not sealing under vacuum. Check for proper operation; clean or repair as needed.
Check for faulty compressed air blowback solenoid. Check for voltage signal during cleaning cycle, proper solenoid operation, incorrect wiring, proper compressed air connection, and for worn plunger in valve.
Material is sucked from the filter chamber and through the blower.
49
Filters in the filter chamber are dislodged, worn, or not seated properly on the gasket.
The material conveyed is not what the system was designed to convey. Very dusty materials have different conveying needs.
Replace or repair immediately. If the exhaust silencer has material in it, replace it to prevent fire hazard
Consult the sales representative for advice on hardware requirements.
