Installation

15

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.

16

4.3. Electrical Connection

 Be safety conscious! High or low voltage can cause serious or fatal injury. Installation

must be performed by qualified personnel only. Always disconnect the power source
before attempting installation or repair.

Refer to local electrical codes, the schematic, and connection diagrams supplied with
this unit and the serial tag for wiring considerations. Run all wiring in conduit if codes
require it. Label all wiring to make any future troubleshooting easier. Make all
electrical connections tight.

Before connection to the electricity supply, ensure that the supply voltage and the power
frequency are in accordance with the data on the nameplate of the machine.

The main power disconnect must be freely accessible.

Ground the equipment against electrostatic charging.

4.3.1. XFC-K

Run electrical cable from the blowback valve to the conveying controller. Check control
schematics for proper terminal connection points.

17

4.3.2. XFC-A

Run electrical cable from the blowback valve to the conveying controller. Check control
schematics for proper terminal connection points.

18

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

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.

21

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

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.
