RECEIVING & INSPECTION
Receiving
VentBoss 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. VentBoss 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 VentBoss 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 VentBoss Representative, call the factory at 1 (855) 558.VENT,
or email: customer.ser[email protected].
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 VentBoss 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 VentBoss
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 400
GENERAL DESCRIPTION
VentBoss G100 Series Portable fume extractors allow
you it to easily convert from a powerful Fume Arm
Extractor to a High Capture Backdraft unit and then to a
capable Downdraft Table all in a matter of minutes (with
optional equipment). Any one of these options can be
changed due to the patent pending, SnapLock design,
enabling the VentBoss to cover nearly every manual
welding process undertaken in your plant.
GENERAL OPERATION
The VentBoss Series 120 Portable has been designed
specifically for manual welding operations that require
mobility. The extra-large 8" fume arm extends to a full 8
foot radius and can swing 270 degrees with ease. The
G122 Backdraft/Downdraft configuration, also equipped
with the quick connect system, has been engineered to
create a horizontal and downdraft suction which diverts
smoke and fumes away from the operator.
Each configuration draws dust-laden 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. Clean air is then
drawn through the exhaust plenum as clean air into the
plant facility.

SECTION 500
INSTALLATION
To operate your new VentBoss Series 100 Portable,
you will simply need to set your position, plug it into a
dedicated 110 volt 20 amp plug and start welding. After
each use, the filter element will need to be back pulsed
(see Pulsing the Series 100 Portable).
Compressed Air Hook-Up
IMPORTANT! First and foremost, your VentBoss Series
100 Portable unit needs a clean, dry, compressed
air source, approximately 80 to 90 PSI. Figures 7
and 8. Many problems can be traced back to the
presence of oil or water in the compressed air system.
If contamination is present, both the cartridge and
cleaning system will suffer.
Electrical Hook-Up
The VentBoss Series 100 Portable comes ready to plug
into a 20 amp, 110 volt service. Figure 9.
Amperage requirements of the single phase, 110 volt
model are found on the product specifications guide.

SECTION 600
OPERATION
Pulsing the Series 100 Portable
(Cleaning the Cartridge Filter)
The VentBoss Series 100 Portable comes equipped with
a Manual Pulsing System (MPS) located just above the
cartridge access door. To operate, compressed air must
be hooked up to the air inlet. Figure 10.
After each days use, press the solenoid plunger 5-15
times to back-flush the filter cartridge. This cleaning
process will loosen the collected particulate from the
cleaning cartridge and it will be collected in the dust tray
below.
For best results, press the solenoid plunger in short,
timed blast of 3-5 seconds between each pulse. The
motor MUST be turned off for this process.
Fume Arm Adjustment
(Models G120, G121, G122, G123)
The Multi-Positional Fume Arm comes factory adjusted
and balanced for maximum ease of mobility. Figure 11.
Position the Fume Arm by pushing or pulling the hood
section over the welding area as shown. Place the fume
hood above and slightly in front of the welding area.
Figure 12. This will keep smoke and fumes away from
the operator. Adjust the Fume Arm hood to maximize
smoke capture.
The VentBoss Fume Arm has two adjustment points,
that can be changed at any time to give the arm greater
flexibility. Figure 13.
Friction disks, located at the base of the arm and at the
first hinge point, can be tightened or loosened with a
12mm wrench. Simply tighten the nut on the friction disk
to make the joint stiffer or loosen to give the joint freer,
less restricted action. Be careful not to
over tighten the disk as this could cause
permanent injury to the arm.
Some fume arms come equipped with a
shock or strut. The shock is not adjustable.

To install the optional FlexDraft as a Backdraft Plenum
simply replace the Fume Arm connector plate with the
FlexDraft Plenum. This is done by releasing the Quick
Connect with an 8mm hex wrench. Turn the latch
clockwise 1/4 turn to release the plate. Replace the
Fume Arm and Fume Arm Plate with the FlexDraft num
by sliding it toward the back of the unit.
This will lock the Flexdraft in place. Once the plenum
has been secured, turn the two 8mm Quick Connect
latches 1/4 turn clockwise to seal the Flexdraft to the
VentBoss Portable.
Once the FlexDraft Plenum is secure, release the
retainer pin from the leg/hood support. Figure 14. Swing
the hood support forward until the hole on the leg lines
up with the front of the hood bracket. Once in place,
slide the weld curtain over the supports and drape over
the backdraft plenum. Figure 15.
Installing the Downdraft Plenum (option)
To install the FlexDraft as a downdraft table, first
disconnect the front cover plate by releasing the two
Quick Disconnect latches. Figure 16. Remove the weld
curtain and lock the hood/leg support in the down
position as shown in Figure 17. With the legs downward,
slide the plenum up and over the exposed downdraft
intake. The plenum will hang in place until you secure
the Quick Disconnects with a 1/4 clockwise turn. Figure
18. Install the front cover plate to the open Backdraft/

GENERAL MAINTENANCE PROCEDURES
Note: These procedures are to be performed while
there is no welding occurring!
Replacing the Filter Cartridge
The premium high grade A15 filter of the VentBoss can
be back – pulsed countless times before it need to be
replaced. Prior to making a decision to replace the filter,
first follow the procedures of “Pulsing the Series 100
Portable” in Section 700. The cartridge can also be
taken out and manually cleaned with compressed air. If
the VentBoss still does not draw sufficiently, then replace
the cartridge.
To replace the filter cartridge, release the filter clamps
by pulling outwards on the two levers located on each
side of the filter. Figure 19. Slide the cartridge out the
door and replace with a new RoboVent filter. Figure 20.
Replacement filters may be ordered by calling VentBoss
at 1-855-558-VENT.
Replacing the Baffle Filter
The VentBoss Series 100 Portable comes equipped with
an internal spark arrestor filter located in front of the
cartridge filter. Figure 21. CAUTION! DO NOT replace
this panel with anything other than what was
originally installed in your portable unit. Failure to
do so will greatly increase the risk of fire.
Placement of the baffle is extremely important as the
baffles should run vertical with cup side facing toward
the front of the collector. Failure to place the baffle as
shown will increase the risk of fire.
Note: A mesh-type filter may be supplied instead of the
baffle in some situations.

VENTBOSS • G120, G121, G122, G123, G124 OWNER’S MANUAL 15
SECTION 700
GENERAL MAINTENANCE PROCEDURES (continued)
FIGURE 22
Cleaning the Spark Arrestor Filter
The spark arrestor filter should be removed and cleaned
on a regular basis. If particulate builds up on the
baffle the risk of fire in the system is greatly increased.
Typically, the filter should be removed and cleaned with
a hot detergent solution every month. Filters that are
bent or deformed beyond repair should be replaced. See
product specifications for ordering a proper replacement.
Dust Tray Removal (Cleaning)
Cleaning frequency of the dust tray will vary depending
on the welding situation and use. Periodically check the
tray for particulate. The dust tray is located immediately
below the cartridge filter and can be accessed through
the filter door. Figure 22.
Dust tray removal should be as follows:
1. Open door, slide out the dust tray and discard the
particulate.
2. Vacuum excess dust and particulate from the walls
and floor.
3. Clean tray and housing with clean rags and an
industrial strength degreaser, (once every 6 months,
or at time of cartridge replacement).
4. Return dust tray to its original position, close and
latch the door.
Blower Maintenance
The blower in your VentBoss Portable 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
VentBoss Technician to balance the wheel and motor.
Contact 1-855-558-VENT.

16 VENTBOSS • G120, G121, G122, G123, G124 OWNER’S MANUAL
SECTION 700
GENERAL MAINTENANCE PROCEDURES (continued)
Solenoid Valve Maintenance
The Pulse Solenoid is located just below the blower
wheel in the Motor Plenum. Figure 23. Under normal
conditions, the pulse valve will last for the life of the
collector. Clean, dry compressed air, at 90 PSI, will
assure long, maintenance free life of the solenoid. (See
Specifications for replacement)
Replacing Metal Mesh Filters in
Backdraft/Downdraft Plenum
The optional Backdraft/Downdraft Plenum comes
equipped with two 20” x 24” x 2” Metal Mesh Spark
Arrestors. It is extremely important that these filters be
cleaned on a regular basis.
CAUTION! DO NOT replace the two Metal Mesh
Spark Arrestors with anything other than what was
originally installed. Failure to do so will greatly
increase the risk of fire.
The two Metal Mesh are located just below the support
grate of the Backdraft/Downdraft Plenum. To access the
filters remove the two screws opposite the hinge side of
the support grate. Figure 24.
Hinge the support grate back until it rest against the front
face of the collector. Figure 25.
Remove both Metal Mesh from the Backdraft/Downdraft
Plenum and replace with new or clean filters. Figure 26.
Cleaning the Metal Mesh Spark Arresters
Both filters should be cleaned with a hot detergent
solution every month. If a high pressure power washer
is used for this process make sure the aluminum mesh
and frame is not bent or deformed beyond repair. See
Specifications for ordering proper replacements.
The inside of the Backdraft/Downdraft of the VentBoss
Series 100 Portable should be vacuumed and cleaned
with an industrial degreaser after 500 hours of use.

VENTBOSS • G120, G121, G122, G123, G124 OWNER’S MANUAL 17
SECTION 800
TROUBLESHOOTING
VentBoss Series 100 Portable 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 VentBoss Technical
Department at 1-855-558-VENT.
Manual Pulse Filter Cleaning System is not operating:
1. Verify that the airline is connected to the air tank.
2. Check air tank pressure. The pulse valve works best when pressurized at 90 – 105 PSI.
3. Check diaphragm on solenoid valve. If optimized pressure is supplied to the air tank
then a problem may exist with the solenoid diaphragm. See product specifications to
order a new diaphragm kit or complete valve from VentBoss Service Department.
Little or no suction across intake. Check the following:
1. Cartridge filter is loaded. Review “Pulsing the Series 100 Portable” in Section 600 under
OPERATION. With the air hooked up press the Solenoid Plunger 25-30 times with a 3-5
second spacing between each pulse. Make sure the unit is turned off for this process.
2. If using a fume arm make sure the butterfly valve behind the intake hood is not closed.
Sometimes this valve will close on it’s own, cutting off most of the air supply.
Cartridge filter loads up but no dust in the dust tray. Check the following:
1. Check that the Manual Pulsing System is working properly.
2. Check for oil or moisture on the filter media. If oil or moisture exists in the air supply it
will transfer to the cartridge.
In some cases high oil content is introduced in the welding process causing the oil to
vaporize. This will cause the cartridge filters to load up prematurely. Call the VentBoss
Service Department at 1-855-558-VENT for more information.
Fume Arm falls when extended:
1. Tighten the friction disk located near the swivel base of the arm. Be sure not to over
tighten. (See Fume Arm Adjustment in Section 600).
2. Fume Arm may be overextended beyond it’s weight limit. Place the arm closer to the
portable.

SECTION 900
INSTALLATION, OPERATION, & MAINTENANCE
General Description & Reservations
VentBoss Base Mount Fume Arms are meant for capturing the welding dusts and gases as
well as fine dusts, straight at the emission source, in order to avoid expanding the impurities
in the process room and being inhaled by people. The arms are manufactured in hanging and
standing version. The extraction arms can work independently with an e traction fan, or in a
group of devices connected to the main discharging ductwork with a central fan.
Producer Reservations:
A. Producer accepts no liability for any consequences following from the operational use
that is in contradiction to the purpose of application.
B. It is unacceptable to install on the structure of the device any additional elements not
belonging to its normal construction or accessory set.
C. Any structural changes or modification of the unit, made by User on one’s own, are not
permitted.
D. Protect the flexible elements as well as the pipes of the suction duct from mechanical
damage.
E. Prior to installing check the load capacity of the wall or other building structure where
the device shall be mounted.
F. The devices cannot be applied for conveying the air containing aggressive
contaminants.
Structure & Function
VentBoss extraction arms are constructed of subsequent assemblies presented in Diagram 1
(See Appendix A):
• Swivel
• Two pipe segments (“I” and “II”) connected together with frictional joints
• Gas springs – to balance the segment weights
• Shut-off damper
• Suction hood with wire mesh protecting the inlet from getting in the burning rests and
chippings.
The swivel guarantees a full rotation of the whole appliance around its vertical axis and
therefore ensures an easy device positioning in the requested point within the workspace.
The swivel and the pipe segments integrated together with hose sections (flexible connectors)
along with the attached hood – are forming a ventilation duct altogether, serving for extraction
the dust laden air. This arm configuration can be changed within the work range of the given
type of the extraction arm. Additionally, the intake air volume can be adjusted by means of
the shut-off damper (installed in the pipe segment “I”). Adequately adjusted frictional joints in
co-function with the gas springs, provide comfort of maneuvering with the extraction arm.
