ROBOVENT • DFS SERIES OWNER’S MANUAL 6
1. The DFS Ductless System
The DFS FloorSaver system is a self-contained air
cleaning unit that captures fumes at the source,
filters impurities and returns clean air into the
work place. Your DFS unit is part of the RoboVent
FloorSaver system that can be customized to any
weld cell configuration and requires no footprint in
the plant.
Energy cost, floor space and improved air quality are
only some of the benefits from the DFS product line.
2. Vertical Filter Design
The DFS ductless system utilizes a vertical
cartridge filter concept to overcome the tendency
for dust in the collector to be re-entrained back
onto the filter cartridges after it has been removed
from the filters by the Self Cleaning System. The
unique design increases filter life by 30% to 40%
over traditional horizontal filter placement.
3. High Performance Blower Design
Each DFS Series Dust Collector comes with Air
Foil blowers with direct drive motors. This highly
efficient blower design and direct drive system
maximizes the airflow (CFM) delivered by the
motor power requirements. (see Figure 2).
4. Filter Self-Cleaning System (FSS)
The DFS FloorSaver Series comes equipped with
an automatic Filter Self-Cleaning System (FSS)
utilizing a calculated pulse of high-pressure air into
the core of the cartridge filters. This reverse-jet
cleaning system can be programmed to best fit
your welding application.
5. Pulse Cleaning Cones and Nozzles
The DFS Model Collector utilizes a special cleaning
cone and nozzle combination which optimizes the
cleaning pulse by ensuring that the developed
overpressure in the filter is even throughout the
filter element. (see Figure 3).

SECTION 200
Features of DFS Series Collectors(continued)
6. Automatic Maintenance Indication
The ePad Controller constantly monitors the
differential pressure between the dirty and clean
sides of the cartridge filters letting you know when
the filters should be changed. The ePad is preset
with default settings to assure the longest life of
your filters. Default settings can be changed to
meet your particular situation. See Appendix A for
changing the default setting of the ePad Controller.
7. Control Panel Station
The DFS Series come fully equipped with all
needed controls in one compact, control panel. The
ePad Controller can be accessed from the front
panel allowing ease in changing the ePad Controller
settings. (see Figure 5).
8. Sturdy 10 GA Reinforced
Collector Housing Construction
This heavy-duty construction secures a lifetime
of industrial use. Seams are robotic welded and
ground to assure there are no leaks or cracks that
could contaminate the facility air system. Each unit
is pre-tested for air leaks during construction and
again before installation.
9. Large Dust Storage Capacity
Your DFS unit comes equipped with an oversized
dust tray. (see Figures 6). The dust tray is designed
to capture and store particulate pulsed off the filter
cartridges and minimize “re-entrainment.”
(Re-entrainment is the term used for picking up
dust that has already been removed from the filter
and re-depositing it on the filter.)
FIGURE 5

SECTION 200
Features of DFS Series Collectors(continued)
10. Front Door Filter Access
Both the spark arrester baffles and the cartridge
filters are easily accessible through the filter access
door. Filter replacement is made easy and requires
less time and effort than traditional side loading
systems. (see Figure 7)
11. 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.
(see Figure 8)
12. Smoke Detection Shut-Down System
Each DFS unit is equipped with a Smoke Detection
Shut-Down System. In the event that a fire or
excessive smoke should appear in the clean air
plenum, the blower wheel and ePad Controller will
automatically shut down and a strobe light will be
activated.
13. High Efficiency Pre-Coated Filters
High efficiency filter media is used in the
construction of the pleated cartridge filters. The
high density, pre-coated filter allows the air to flow
slowly past the filter media to lay the dust gently
on the outside surface, allowing it to be pulsed off
easily. Filter construction, media and the pre-coat
process assures more efficient smoke capture and
longer filter life.

Receiving
RoboVent Equipment is typically shipped on skids or in crates. The number of skids/
crates will vary, depending on the type, size and accessories ordered. These skids/
crates are too heavy to lift by hand, and will need to be unloaded by an industrial fork-
truck or similar equipment.
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, or call the factory at 1-(888)-762-6836.
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.
SECTION 300
Receiving & Inspection

ROBOVENT • DFS SERIES OWNER’S MANUAL 10
The DFS Series Collectors are a compact, continuous
duty, self-contained dust collector. The units consist
of a housing with blower, motor, integral silencer, filter
cartridges, spark arrester baffles and pulse cleaning
system. (see Figure 9).
The Filter Self-Cleaning System (FSS)
The DFS Series is a reverse jet-pulse dust collector
with a powerful Filter Self-Cleaning System (FSS).
The FSS utilizes a calculated reverse jet-pulse of air
into the inner core of the cartridge filter. (see Figure
10). This shock wave of reverse air will dislodge
particulate that has caked on the outside of the
cartridge filter. As the filter cartridges are mounted
vertically, the dislodged dust eventually works its
way down to the lower collection tray. This process
reconditions the filter media and can prolong
cartridge life for several months (filter life depends
upon your application).
General Operation
Dust and smoke laden air is drawn through the floor
of an enlarged intake plenum where it passes through
a dual layered spark arrestor before entering the
cartridge plenum. Dust particles are then collected on
the surface of the pleated filter cartridges as air flows
through the high efficiency media and into the clean air
duct. Recycled air is then exhausted by the blower fan
through an acoustically designed motor plenum.
To operate your new DFS unit, you will need to connect
both electrical power and compressed air.
See “Installation”.

The DFS Collectors require a 3 phase, 460 volt
electrical feed. (Other voltages are also available).
Amperage requirements for the motor can be found
under “Specifications” for the particular DFS model.
Electrical connections should only be done by a
licensed electrician and in accordance with NEC and all
applicable local codes.
Note: The complete enclosure of the DFS Model is
CSA certified. The control panel and all electrical
mechanical components are UL certified. CSA and UL
certification numbers are located on each component
and or on the control panel door and the cartridge filter
door. If further documentation is needed for CSA or UL
certification contact the RoboVent Service Department
at 800-470-3430.
A 460 volt, 3 phase service should be connected to the
provided lugs inside the J-box as shown in Figure 11.
Compressed Air Hook-Up
IMPORTANT! First and foremost, your DFS unit needs
a clean, dry compressed air source, approximately
90 PSI. Many problems can be traced back to the
presence of either oil or water in the compressed air
stream. If contamination is present, both the cartridges
and cleaning system will suffer.
The DFS series come complete with an air regulator
and accumulator. In most cases the provided
accumulator will trap a low volume of oil and water in
your systems air lines. In some rare cases however, a
larger accumulator might be needed.
On the back of the DFS unit is a 3/4" pipe for
connecting the provided air regulator. Install as shown
in Figure 12.

After running the DFS for 50 hours unscrew the filter
element from the accumulator housing and examine
the filter element. If the element already shows
excessive contamination, a larger accumulator will
need to be installed. A dryer may also need to be
placed in the line before the accumulator.
Blower Rotation
IMPORTANT! Check blower rotation of the unit
by jogging the motor. Blower rotation should be
CLOCKWISE when viewed from above the unit. The
blower will still draw air if the motor is running
backward but the air draw will only be a fraction of
what it should be! (see Figure 13).
A visual inspection will verify that the motor is turning
clockwise when viewed from above the unit.
Accessories
If your DFS Dust Collector is supplied with some of the
available optional accessories, these may need to be
wired into the system.
Auto On/Off Option
For the Automatic Operation Option, the supplied current transformer must be positioned
around one of the power conductors to the welding power supply, and secured so as to avoid
physical damage. This usually involves disconnecting the conductor, installing the current
transformer, and then re-connecting the system.
Fire Suppression System
Your DFS equipment comes standard with the “Smoke Detection Shut-Down” system. This
equipment will shut down the blower and ePad Controller but will not extinguish a fire. The
optional Fire Suppression System uses a FM-200 agent to suppress a fire along with extra
controls that shut off the intake and exhaust plenums. This system is wired into the control
panel when purchased with the equipment.
Automatic VFD Drives
A Variable Frequency Drive (VFD) Option is also available on the DFS equipment. VFD’s and
velocity transmitters are pre-wired into the control panel and DFS unit.

Before operating your DFS Dust Collector, double
check the following items:
1. Be sure all electrical connections are secure and
wired properly.
2. Double check blower rotation. (see Figure 13).
3. Check the compressed air connection.
4. Before starting the unit make sure the motor
plenum door is locked shut.
Starting the DFS Collector
The DFS system comes complete with full electrical
controls and automatic pulsing system. The entire
contents of the control systems are installed inside the
electrical enclosure.
The Electrical Control Panel inside the equipment
cabinet contains the Service Disconnect, Motor
Starters and Controller. With the Service Disconnect in
the “ON” position press the “SYSTEM START” button
on the touch screen (this may either be remote, or
mounted on the unit) to energize the control system,
then continue through the “MAN FAN” and “LIGHTS”
and/or “START MODE” screens (if these option are
applicable) to the “BLOWER CONTROL” to engage the
Motor Starters and start the system blowers.
Auto On/Off Option
If your system is equipped with the Auto-Start Feature,
a “START MODE SELECTOR” screen will appear during
the above process (see Figure 15). Touch the selector
switch image to toggle between HAND and AUTO. In
the “AUTO” mode, the blower is cycled automatically
when triggered by welder operation and automatically
turns the unit off after approximately 3 minutes of
inactivity. The “HAND” position overrides this function
and the blower operates continuously.
