Cartridge Dust Collector
1. IMPORTANT NOTICE
This manual contains specific information concerning
safety and precautionary measures. It is impossible to
list every potential hazard associated with dust
collection equipment or systems. Use of the equipment
must be discussed with a factory-trained, United Air
Specialists, Inc. (UAS) representative. As always,
please adhere to the most stringent safety procedures.
2. INTRODUCTION
Thank you for selecting United Air Specialists dust
collection equipment to assist you in your commitment
to a clean and safe environment.
2.1 UNIT NOMENCLATURE
Collection Method:
B = Downdraft Bench
F = Fixed Ducted Unit
P = Portable Unit w/ Swing Arm
Nominal Flow Rate:
750 = 750 CFM
1500 = 1500 CFM
Example:
VB-1500
This would be a downdraft bench with a nominal airflow
of 1500 CFM.
2.2 DESCRIPTION AND OPERATION
The V Series Dust Collection System is a high-
efficiency, cartridge dust collector designed to eliminate
airborne particles as they are generated. Contaminant
is captured at its source by a unit-mounted hood,
downdraft table or ducted inlet and then conveyed
through the cartridge filter section where it is collected.
Clean air is then recirculated back to the work area.
There are two primary cycles of normal operation for
the V Series — the air filtering operation and the filter
cleaning cycle utilizing a compressed air cleaning
system.
Figure 1 shows the basic system operation and
equipment of a V Series dust collector.
2.3 AIR FILTERING OPERATION
The contaminated air stream is drawn into the collector.
Once the dust-laden air enters the cabinet, it meets a
baffle plate that disperses the air and significantly
reduces the air stream velocity. This provides even
distribution of the air stream across the entire surface
area of the cartridge filters, allowing a uniform dust
cake to form. The reduced air stream velocity causes
the heavier particles to fall out and collect in the dust
drawer.
The air stream then passes through the cartridge filter
where it is stripped of the particles by the media.
Cleaned air flows through the center of the filter,
through the blower (and optional safety after filters and
exits through the rear of the cabinet, back into the
workplace.
2.4 FILTER CLEANING CYCLE
As the cartridge filter becomes loaded with
contaminants, it becomes necessary to clean the filter
to maintain adequate airflow.
The compressed air cleaning mechanism provides brief
bursts of compressed air into the cylindrical cartridge
filter. When actuated, the cleaning system directs 90-
100 PSI of customer supplied compressed air through a
pulse valve, into a blow pipe, creating a burst of
pressure through the inside of the cartridge filter. This
pressure dislodges the dust and reduces the pressure
drop across the filter so the system can maintain
adequate airflow.
3. SPECIFICATIONS
Air Collection Method:
The V Series dust collector comes in three basic dust
collection configurations.
1. Downdraft Bench Unit (VB)
2. Fixed Ducted Unit (VF)
3. Portable Unit w/ Swing Arm (VP)

4. INSTALLATION
4.1 OFF LOADING AND INSPECTION
The V Series dust collector is shipped in two or three
containers depending on the configuration and options
selected. The first consists of the unit cabinet and
filtration components. Other container(s) may contain
the extraction arm, downdraft bench, etc.
Upon receipt of your unit, check for any shipping
damage. A damaged carton indicates that the
equipment may have received rough handling during
shipping that may have caused internal damage. Notify
your delivery carrier and enter a claim if any damage is
found.
Remove the filter access cover (located on the front of
the unit) by turning the black knob counterclockwise to
release the cover. Examine the seal between the
tubesheet (the vertical panel between the blower
section and the filter section) and filter. Make sure filter
or gasket has not become displaced during shipment
(refer to Section 6.1, Cartridge Filter Removal and
Replacement). Replace covers once inspection is
complete.
4.2 INSTALLATION
Different models of the V Series collector require
different assembly techniques. Please see the
techniques in the subsequent sections for
your V Series dust collector.
All models of the V Series will require minimum
clearances and access in order to perform routine
maintenance and service. Be sure to leave access for
filter removal, the dust drawer release lever and
blower/pulse valve access through the discharge
panel as shown in Figure 1.
4.2.1 PORTABLE INSTALLATION (VP MODEL)
The top of the V Series cabinet has either one set
of six (VP-750) or eight (VP-1500) threaded studs to
mount the swing arm. The necessary hardware is
pre-assembled the studs. When mounting the arms
on the unit, a ceiling height of about 10’ is required for
adequate clearance. Two people are suggested for
positioning the swing arm and securing into place.
1. Remove the swing arm from its shipping
containers and assemble per the swing arm
manual provided.
2. Remove nuts, lock washer and flat washer from
the studs on the cabinet (refer to Figure 2).
3. Position flange gasket(s) inside the protruding
studs on top of the unit (refer to Figure 2).
4. Position the swing arm mounting base into place
over the mounting studs. Ensure gasket is
positioned properly between unit and base
flange. Secure swing arm to cabinet top with the
recently removed hardware (refer to Figure 2).
Avoid sharp pulls on the arm or hood as well as
over-tightening the pivot section since damage to
the arm components could result.

4.2.2 DOWNDRAFT TABLE ASSEMBLY (VB MODEL)
The V Series downdraft table (VB) comes packaged,
requiring some assembly before using. Follow the
steps below to complete the assembly.
1. Begin by securing the two side panels as shown
in Figure 3. Thread all four fastening knobs into
the cabinet leaving enough space for the side
panel to fit over top of threaded knob stud.
2. Lower each panel as shown onto the knob studs
and then tighten knobs until panel is secure.
3. Lower the back panel into rear aligning tray and
side panel guide slots.
4.2.3 FIXED UNIT ASSEMBLY (VF MODEL)
The fixed unit assembly typically requires some type of
customer-supplied ductwork to convey the dust from the
source to the collector. See Figure 4 for a typical
installation.
Care should be taken when sizing and laying out the
ductwork in order to minimize loses through the system.
Figure 3. Downdraft Table Installation Detail
61-10037-0001
4.3 PULSE CLEANING
If your V Series system came with a cleaning system,
please review the following section for optimum
performance.
Provide a clean, dry, 90-110 PSIG compressed air
supply to the compressed air manifold. The supply
coupling (1" NPT) is located on the lower center of the
unit’s rear panel as shown in Figure 7. A reducer
bushing may be required for your supply line.
Compressed air supply to the unit can be a flexible
quick disconnect air line from a ceiling-mounted hose
reel or similar supplied plant air. The hose size can be
between 1/4” and 1” diameter.
The compressed air usage per cleaning cycle can be
found in Table 1. Note that the cleaning system will only
operate when the motor/blower is off. See Section 4.4.1
for adjustments available with the timer board.
4.4 ELECTRICAL INSTALLATION
The V Series unit has a wide variety of available
electrical options to best meet your needs. Take care
to ensure proper installation in whatever configuration
you have selected.
For units only requiring a 115-volt, single-phase power
supply, your unit will be supplied with a 15-foot power
cord and plug and is electrically ready for operation. If
the unit has a 230-volt, single-phase power supply, the
unit will be provided with a power cord but the customer
will be responsible for supplying and attaching the
appropriate plug.
For units requiring three-phase power, there are two
basic options. If UAS is supplying the motor starter, the
unit will be equipped with a 15-foot power cord without
a plug.
NOTE: All VP Series units come standard with a UAS
supplied starter
If the customer is supplying the motor starter, no cord,
motor overload protection or control transformer will be
provided.
Refer to Appendix A of this manual for the
recommended wiring diagrams of your V Series unit.
4.4.1 PULSE CONTROL TIMER BOARD
Before making any changes to the Pulse Control
settings, please read this section of the manual.
The Pulse Control timer board has been designed to
pulse a single solenoid valve that supplies a pulse of
compressed air to a dust collector filter. Unless
otherwise specified, the timer board is factory set to a
0.1 second pulse duration, 10 second pulse delay, and
1 downtime cleaning cycle.

DOWNTIME CLEANING OPERATION
1. Turn the CLEAN switch to the ON position. The PWR
light will be ON.
2. When the CLEAN CONTROL contacts (#13 and 14)
are shorted, the CLEAN light will be ON.
3. When the CLEAN CONTROL contacts open, the
CLEAN light will flash for the duration of the cleaning
cycle.
4. After the 60-second blower coast down delay, the
valve output (V and N) will turn on for the selected
length of time (100 or 150mS).
5. If more than one pulse is selected (2, 4 or 6), there
will be a 10 or 30 second delay as selected between
the pulses.
6. When the cleaning cycle is complete, the CLEAN
light will turn OFF and the control board will wait for
the CLEAN CONTROL contacts to close again.
If at any time during the cleaning cycle the CLEAN
CONTROL contacts close, the cleaning cycle will be
aborted, the CLEAN light will stop flashing, and the unit
will wait for the CLEAN CONTROL contacts to open.
The unit will NOT remember how many pulses were
previously performed; and the cleaning cycle will start
again from the beginning.The position of the four
"white" switches on S1 determine the number of pulses,
the length of the pulse and the delay between pulses.
The position of the switches are read when the CLEAN
CONTROL contacts open, and will not affect the
cleaning cycle if changed during a cleaning cycle. (See
Figure 5 for Cleaning Control Switch Settings)
Upon motor/blower shutdown, downtime cleaning will
only be performed if the CLEAN SWITCH is in the ON
position before the motor/blower is turned OFF. During
downtime cleaning, the CLEAN light will flash for the
duration of the cycles selected.
5. OPERATION
5.1 START-UP
1. Position unit in desired location.
NOTE: Do not attempt to move the portable unit by
pulling on the swing arm or hood. Use the full-
width, bar-type handle on the back of the unit to
push the V Series into the desired location. After
the unit is situated, use the locks on the rear
wheel casters to secure the unit.
2. Plug the unit into a properly grounded electrical
receptacle.

6. SERVICE
Figure 7. Rear Access
61-10039-0001
Collected dust may be hazardous. Consult proper
authorities for handling and disposal.
4. The filter monitor gauge should read between
0.1" and 0.5" w.g. while unit is operating with
clean filters.
5. The discharge plenum on the V Series collector
can be rotated in 90Ýincrements to direct the
discharge air in multiple directions. The discharge
housing will be factory installed with the discharge
pointing towards the floor as shown in Figure 7.
Collecting Particles
1. Locate the unit, arm and hood in the best position
to collect contaminants as generated by the
process or operation, and where operator
interference is minimal.
2. Position the hood to minimize the influence of
cross drafts from outside air sources or other
operations.
3. Position the hood slightly higher than the source,
with the face of the hood approximately 45° from
horizontal. The hood shape is designed for high-
velocity pick up. It should be located as close to
the source as practical and no further than 14-16"
from the contaminant source.
3. Check diaphragm valves to ensure proper pulse
cleaning. With the cleaning cycle activated, the valve
should pulse at approximately 10-second intervals.
Remove lid of control panel enclosure to view the
timer.
4. Check the filter monitor gauge at start-up. The
cleaning system should be activated when the gauge
has increased 0.5" w.g. above the start-up pressure
drop. Allow unit to pulse clean until the original
reading is achieved or until the gauge reading will
not decrease after six consecutive pulses.
5.2 CHECKLIST
1. Check the clean air outlet. Discharge air should
remain visibly clean. If a leak should develop, it will
be first noticed after a cleaning pulse as a puff of
dust.
2. Check pressure drop on the pressure gauge
(see Figure 6). Pressure drop across elements is
considered normal between 0.5-5.0" w.g. Pressure
drop will generally read between 1-2" for “seasoned”
filters.
The following procedure requires access to an area of
the unit where high voltage is present. Access should
be restricted to qualified personnel.
Figure 6. Control Panel Layout Detail
61-10039-0002
3. Turn the unit on by pushing the "Power" rocker
switch to the ON position (refer to Figure 6). On
3-phase units, fan rotation will need to be verified
by matching fan rotation with the rotation decal on
the blower housing. Rotation should be clockwise
as viewed from the motor or drive side. Any two
motor starter leads should be reversed if the
rotation is not correct.

1. Collected dust may be a potential fire hazard. Refer
to Section 1 of this manual.
2. Wear appropriate protective clothing.
3. Be environmentally aware of collected dust and its
proper disposal.
4. Press unit function switch to OFF position. Unplug
unit from electrical power source.
5. Disconnect compressed air supply to air manifold
inlet and bleed air supply from manifold.
6.1 FILTER REMOVAL AND REPLACEMENT
As the V Series unit operates and the filter accumulates
dust, the flow rate of the unit will deteriorate. When the
pressure drop across the filter continuously reads
between 2"-3" or flow drops off to the point where the
dust generation process cannot adequately be
controlled, then it is time to change filters. To change
filters follow these steps:
1. Remove filter access cover by unscrewing the
retaining knob (see Figure 8). Tilt cover back away
from unit when freed from the retaining nut to trap
any fugitive dust on the inside of the access cover.
Dump dust into suitable disposal container.
2. Move filter from side to side to break gasket seal
between the filter and the tubesheet. Rotate the filter
180° to allow dust on top of the cartridge to fall into
the dust drawer.
3. Slide filter out along support rods and transfer to
suitable disposal container. Empty dust drawer as
described in Section 6.2.
4. Inspect tubesheet and make sure the gasket sealing
area is free of dust to ensure a proper seal.
5. Install a new filter element. Clean access cover
gaskets and reinstall cover by tightening the knob
securely to the retaining nut until the gasket is
adequately compressed.
Figure 8. Cartridge Filter Removal

6.2 DUST DRAWER REMOVAL
1. To access and remove the dust drawer located at the
base of the V Series unit, you must first unseal the
drawer by pulling the drawer release handle (see
Figure 8) toward the filter access side of the cabinet.
The drawer will move down and can be pulled out of
the front of the cabinet.
2. Dispose of the collected dust into a suitable
container. Any dust in the cabinet that was not
contained in the dust drawer should be vacuumed
out and disposed of.
3. Replace dust drawer by fully inserting into unit, and
reseal the drawer by pushing the drawer release
handle toward the control panel.
The collector should now be ready to operate. Reconnect
electrical power and air supply. Go through initial start-up
checklist to ensure proper unit performance.
6.3 AFTER-FILTER REMOVAL/INSTALLATION
If your unit was ordered with a HEPA or carbon after-filter,
there will be an additional filter housing bolted to the
discharge side of the V Series unit. The following steps will
allow you to remove and replace the after-filter as shown in
Figure 9. NOTE: After-filter housings for portable units (VP)
have a push handle located on the top of the housing.
1. Release the four draw latches located on the filter
housing to release the seal of the after-filter.
2. Remove the exhaust screen.
3. The after-filter will slide out of the housing as shown
in Figure 9. Keep in mind that the filter weight may
significantly increase from the collected material.
Dispose of filter properly.

replace fuse. If F2 is open, replace board.
1. Make certain 120VAC power is at terminals L and N even after the
motor/blower is turned off. The PWR light should be illuminated.
2. In units with motor starters: make certain an isolated normally open
motor starter auxiliary contact is wired to terminals 13 and 14 (downtime
cleaning begins when the motor/blower starter is turned off.)
1. Check terminals V and N for 120VAC pulse. If no output when PULSE
light flashes, replace board. If 120VAC pulse is detected, check wiring,
valve coil and air supply.
