SECTION 100
Important
Safety Instructions

8 ROBOVENT • PFX SERIES OWNER’S MANUAL
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.
7. If welding stainless steel, special safety measures need to be
followed when maintaining collector. Consult your Safety
Director for further information on OSHA's Hexavalent
Chromium Standards.

Features of the
PFX Series Collector

10 ROBOVENT • PFX SERIES OWNER’S MANUAL
SECTION 200
Features of the PFX Series Collector
1. Filter Pressure Gauge
The control panel houses a Minihelic Differential
Pressure Gauge. This meter will aid the operator in
determining when cartridges should be changed
(see The Differential Pressure Gauge under
Operations).
2. Sturdy 10 GA Reinforced Construction
This Heavy-Duty construction secures a lifetime of
industrial use. Seams are robotically welded and
ground to assure there are no leaks or cracks that
could contaminate the facility air system.
3. Built-In SparkOut Plenum
RoboVent’s SparkOut Technology has been
incorporated into a specially designed crossflow
intake plenum. The intake creates a horizontal
airflow through the built-in SparkOut where sparks
are quickly extinguished. This exclusive engineered
design represents years of extensive field testing and
performance under heavy manual welding.
4. High Performance Blower Design
Each PFX Series Dust Collector comes with a single
Air Foil Blower with a direct drive motor. This highly
efficient blower design and direct drive system
maximizes the airflow (CFM) delivered by the motor
power requirements.
5. Front Door Filter Access
Filters are easily accessible through an
oversized front door. Filter replacement is made
easy and requires less time and effort than
traditional loading systems.
6. Acoustic Motor Plenum
High-density sound materials and Bass Trap
Acoustics have been implemented as part of
the blower compartment. The acoustically
designed plenum greatly reduces motor and
blower noise levels and decreases ambient
noise into the facility.

Receiving &
Inspection

12 ROBOVENT • PFX SERIES OWNER’S MANUAL
Receiving
RoboVent equipment is typically shipped on skids or direct loaded. The number of
skids will vary, depending the type, size and accessories ordered. The skids or direct
loaded equipment are too heavy to lift by hand. The items will need to be unloaded by
an industrial forklift, crane, or overhead crane.
Inspection
A visual inspection of your equipment should be performed before it is removed from
the truck. Dents, scratches, and other damages should be noted on the shipping
documents, and also photographed. The structural integrity of the housing can
be adversely affected by large dents. RoboVent should be immediately notified
of any structural damage to your equipment. It is the purchaser’s responsibility to
file shortage reports and damage claims with the carrier and with your RoboVent
Representative. The carrier is responsible for any damage to the equipment while it is
in transit unless specific arrangements are made otherwise.
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].
When all skids are completely unpacked and uncrated, check all items 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.

General Description

14 ROBOVENT • PFX SERIES OWNER’S MANUAL
SECTION 400
General Description
The PFX Series Collectors are a compact, self
contained dust collector unit specially designed
for ambient welding operations. Each PFX comes
outfitted with properly sized high-pressure blower, an
integral SparkOut Plenum to knock down the most
persistent sparks, and a complete electrical system.
General Operation
Smoke, dust and sparks first enter the PFX via the
SparkOut Plenum. Sparks, created through the
welding process, are quickly extinguished through
an engineered spark trap (SparkOut). Dust laden air is
then drawn through a series of box & bag filters and
returned into the facility as clean air.
Particulate and by-product contamination is
immediately stopped in its tracks by the High-
Efficiency Media.
RoboVent Acoustic Exhaust Plenum
RoboVent Acoustical Plenums are attached at the
outlet of the PFX.
