ROBOVENT • PRC SERIES OWNER’S MANUAL 5
Failure to follow all instructions may result in electric
shock, bodily injury and/or destruction of the unit.
Use of controls, adjustments, or performance of
procedures other than those specified herein, may
result in electrical shock.
IMPORTANT SAFETY INSTRUCTIONS
1. Read all instructions thoroughly.
2. Heed all warnings.
3. Do not block intake or exhaust vents. Keep the exhaust
vent free from debris and materials that could restrict
airflow. Prolonged restriction could damage the motor and
electrical components. Any blockage of the air flow will
decrease efficiency of this unit.
4. Refer all service matters to qualified service personnel.
Servicing is required when the unit is damaged in any
way including the control panel, supply wiring or in the
case of excessive filter loading.
5. Disconnect power before working on the motor or
blower wheel. The motor or blower wheel should be
disassembled only by a factory authorized technician.
6. Risk of serious personal injury or death!
Use extreme care to make sure you are never in a
position where your body (or any item you are in contact
with, such as a screwdriver or test instrument) can
accidentally touch the blower wheel.

Features of the PRC Series
1. Vertical Filter Design (Standard):
Vertically aligned filters allow the dust to shed
off the filter and fall directly down into the
containment system.
2. Easy Access “Easy Load” Filter System
For your convenience the RoboVent PRC is designed
with a top load filter system, which allows the filter
to be removed in seconds. Figure 1.
3. Heavy Duty Construction
Unlike most portables, the RoboVent PRC is made
from heavy 12 and 16 ga steel. Seams are robotically
welded to assure there are no leaks or cracks that
could contaminate the facility air system.
4. Locking Wheels
The RoboVent PRC comes standard with two stage
locking caster wheels which lock the unit in all four
directions. Figure 2.
5. Built-In Acoustical Sound Plenum
High Density Foam Barriers and Built-In Acoustical
Bass Traps have been engineered into the RoboVent
PRC design to make it one of the quietest portables
in today’s market. The RoboVent PRC's quiet 70 dBA
sound rating will not add to your shop's ambient
noise level.
6. Durable Powdercoat Finish
For long lasting durability the RoboVent PRC
is fully powder coated with an industrial grade
textured finish.
7. High Performance Blower
The aluminum Acoustafoil blower is the heart of
the RoboVent PRC. This High Performance Blower is
engineered for High Output air volume.

Features of the PRC Series
8. Carbon Pre-Filter
Your RoboVent PRC is equipped with a MERV
8 Carbon Pre-Filter that will remove larger
contaminants and odors, and help extend the life of
your primary Cartridge Filter. Figure 3.
9. A15 PleatLock Premium Cartridge Filter
A15 PleatLock premium filter media is a proprietary
cellulose polyester blend with an initial Minimum
Efficiency Reporting Value of 15 (MERV15). The base
media is enhanced with a direct-spray nanofiber to
promote surface loading during operation and dust
release during pulse-cleaning.
Optional HEPA E11 (>95% Efficiency, comparable
to N95 Mask) and HEPA H13 (>99.95% Efficiency,
comparable to P100 Mask) are also available.

Receiving & Inspection
Compare the number of items received against the carrier’s bill of lading. Inspect all
items for apparent damage. Immediately report any shortages or obvious damage to the
carrier and to your local RoboVent Representative, call the factory at 1-(888)-762-6836,
or email: [e-mail].
Check that all items have been received against the packing lists. Further inspect the unit
and components for hidden damage. Again, report any shortage or damage to the carrier
and to your local RoboVent Representative.
The filter cartridges are typically shipped installed in your collector. Be sure to check them
for alignment, as they may have shifted during transit. If they have shifted, it is possible
that damage may have been done. Remove all filter cartridges and inspect thoroughly.
Note: Do not return any damaged components without first contacting your RoboVent
Representative to obtain a Returned Goods Authorization (RGA).
Small Parts
Carefully inspect all packing material before it is discarded, to be sure that no small parts
have been missed.

Installation/Operation
Electrical Hook-Up
The RoboVent PRC comes ready to plug into a 20
amp, 110 volt service. Figure 4. (If ordered as a 480 volt,
3-Phase model the connection must be made by a
licensed electrician and in accordance with NEC and all
applicable local codes.) Amperage requirements of the
single phase, 110 volt model are found on the product
specifications guide.
General Operation
The RoboVent PRC has been designed specifically
to create a horizontal suction which diverts harmful
particulate away from the operator. The unit draws
air through a secondary internal baffling design that
causes separation and deposition of the larger, heavier
dust particles. These particles are diverted to the dust
storage device thus reducing the dust load to the filter
cartridges. Finer particles are collected on the surface
of the filter cartridges but will eventually be dislodged
through the manual pulsing system (if purchased). Clean
air is then drawn through the exhaust plenum as clean
air into the desired air.
To operate your new RoboVent PRC, you will simply
need to set your position and plug it into a dedicated
110 volt 20 amp plug.

General Maintenance Procedures
Note: These procedures are to be performed while
there is no welding occurring!
Replacing the Filter Cartridge
The A15 PleatLock premium filter of the RoboVent PRC
can be back – pulsed countless times before it need
to be replaced. Prior to making a decision to replace
the filter, first follow the pulsing procedures outlined in
General Operation in Section 400. The cartridge can also
be taken out and manually cleaned with compressed air.
If the RoboVent PRC still does not draw sufficiently, then
replace the cartridge.
PRC-1200: To replace the filter cartridge, release the
filter clamps by pulling outwards on the two levers
located on each side of the filter. Figure 5. Slide the
cartridge out the door and replace with a new RoboVent
filter. Figure 6.
PRC-800: Replacing the filter cartridge is as easy as
opening the top hatch door and removing the filter. Be
sure to clean all dust and debris from the filter plenum
before replacing the cleaned or new filter cartridge.
Figure 7.
Replacement filters may be ordered by calling RoboVent
at 1.888.ROBOVENT.
Blower Maintenance
The blower in your RoboVent PRC will require very little
attention, although it is important to make sure it is kept
clean. If your motor is fitted with grease nipples, they
must be lubricated every six months.
Installation of a new blower wheel requires a certified
RoboVent Technician to balance the wheel and motor.
Contact 1.888.ROBOVENT.

Troubleshooting
RoboVent PRC is making excessive noise. Check the following:
1. Make sure the blower wheel is not hitting the venturi.
2. Check that all motor bolts are securely tightened.
3. Make sure motor bearings are good. (Amperage rating will be higher than
normal.)
4. Blower wheel could be out of balance. If the blower wheel has gone out
of balance, there will be excessive vibration. In this case, please contact the
RoboVent Technical Department at 1.888.ROBOVENT.
Little or no suction across intake. Check the following:
1. Cartridge filter is loaded. Review the pulsing instructions in General Operation
Section 400. With the air hooked up press the Solenoid Plunger 25-30 times (if
applicable) with a 3-5 second spacing between each pulse. Make sure the unit is
turned off for this process.
