SECTION 200
FEATURES OF THE SERIES 300 COLLECTORS
1. Quiet Operation
A built-In acoustic lining of high density sound
absorbing materials has been implemented as part of
the blower compartment. The acoustically designed
plenum greatly reduces motor and blower noise
levels and decreases ambient noise to the facility.
2. Heavy Duty Construction
Each VentBoss Series 300 fume collector comes
with our heavy duty 14 gauge steel construction and
quality built guarantee. A durable high temperature
cure powdercoat finish give excellent long term
protection to the cabinet.
3. Easy Access Filter System
For your convenience the VentBoss Series 300 units
are all designed with our proprietary SnapLock
filter system, which allows the filter to be removed
in seconds. Changing filters is a rapid and simple
procedure, and eliminates any need to undo nut,
bolts or threaded components , which are particularly
prone to clogging and jamming inside a dust collector
cabinet.
4. High Grade Merv 13 Filter
A High Grade, Fire Retardant, hybrid poly/cellulose
Merv 13 Filter comes standard with each VentBoss
Series 300 unit which contributes to its high efficient
filtration. This durable filter media is manufactured
specifically for welding and metal working operations,
giving extended filter life, enhanced by the filter pulse
cleaning system to pulse off captured dust, smoke
and particulate. (Figure 1)

FEATURES OF THE SERIES 300 COLLECTORS (continued)
5. High Performance Blower
The aluminum Acoustafoil blower is the heart of the
VentBoss Series 300 units. The backward inclined
centrifugal blower is dynamically balanced when the
complete unit is assembled, prior to the unit being
approved to ship from the VentBoss assembly plant.
(Figure 2)
6. Built-In Spark Arrestance
The VentBoss internal SparkOut plenum quickly
extinguished sparks created through the welding or
grinding process.
7. Built-In Pulse Cleaning
A powerful back flush cleaning system delivers high
pressure air into the inner core of the cartridge filter.
This powerful cleaning system releases dust cakes
from the outside of the filter where they are collected
in the containment for removal.

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.

EQUIPMENT CONFIGURATIONS (continued)
Model: S350
The VentBoss S350 is a unique and simple solution for
processes that produce smoke and fumes. The smoke
is drawn up to the canopy and away from the worker
making it a cleaner and safer environment for each
employee.
The model S350 includes a 64" x 60" wide hood, 83"
high, Pulse Cleaning System and rated for 1500 CFM @
4.5" W.G.
Each VentBoss S350 unit can be set up for different
applications. Call 1-855-558-VENT to talk with one of
our professional consultants to set up your VentBoss for
custom applications.
Models: S320 and S321
The VentBoss S320 and S321 operate on a “Back Draft”
principle. They can potentially draw the smoke from
as far as 30" away from the worker as shown in the
diagram. The smoke is then filtered through the high
efficiency Nanofiber MERV15 cartridge filter and returns
clean air to the plant.
The S320 is configured to stand on the floor and sit on
3" x 6" tubular legs that double as fork pockets.
The S321 can be wall or ceiling mounted above the
work site to save valuable floor space.
Large Smoke Capture Area
The VentBoss S320 and S321 have the largest smoke
capture area than any equivalent backdraft unit available
currently. The VentBoss S320 and S321 has been field
tested and has a capture area of over 30" away from
the face of the backdraft intake.

INSTALLATION
FIGURE 3
Electrical Hook Up
To operate your new VentBoss Series 300 collector, you
will simply need to place it in positon and connect your
460 Volt, 3 phase power supply to the provided Electrical
Disconnect shown (Figure 3).
Electrical connections should only be done by a
licensed electrician and in accordance with NEC and all
applicable local codes.
IMPORTANT: when the motor is started for the first time,
it is essential that the direction of the blower wheel is
checked. (Figure 4) When looking down through the
outlet grille on the top of the unit, the blower wheel
must be rotating in a clockwise direction, also shown
by a sticker adjacent to the blower wheel. If it is
running in reverse, air will still be drawn through, but
at a fraction of the designed volume, and will produce
excessive noise and potentially vibration. To correct
this reverse rotation of the blower wheel, swap the
terminal attachment position on 2 of the 3 phase wires
connected to the Disconnect.
Amperage requirements of all models are found in the
Equipment Specifications Sheets.
Compressed Air Hook-Up
IMPORTANT! The VentBoss unit needs a clean, oil-free,
dry compressed air source, 85 PSI MAXIMUM.
Many problems can be traced back to the presence
of oil or water in the compressed air system. If
contamination is present, both the filter cartridges and
pulse cleaning system will be damaged.
An appropriately sized quick fit air-line connector will
need to be threaded into the provided 1/2” NPT adapter.
A permanent line can be directly connected to the accu-
mulator tank or a shop air hose can be used when pulse
cleaning the filters. (Figure 5)

Pulsing the VentBoss Series 300 Collector
(Cleaning the Cartridge Filter)
VentBoss Series 300 Collectors come equipped with
a Manual Pulsing System located on the front or right
side of the collector. To operate, compressed air must
be hooked up to the air inlet. (See Compressed Air
Hook-Up Section 500)
After each days use or when the filter differential
pressure has built up due to accumulated particulate,
press the solenoid plunger (Figure 7) 5-15 times to
back-flush the filter cartridge, leaving sufficient time
for the air tank to recharge between each press. This
cleaning process will loosen the collected particulate
from the cleaning cartridge and will be collected in the
tray below. Best results will be achieved when the
motor is turned off for this process.
Fume Arm Adjustment (for models with Fume Arms)
The Multi-Positional Fume Arm comes factory adjusted
and balanced for maximum ease of mobility.
Position the Fume Arm by pushing or pulling the hood
section over the welding area as shown in the photo
below. Place the fume hood above and slightly in front
of the welding area. This will keep smoke and fumes
away from the operator. Adjust the Fume Arm hood to
maximize smoke capture. (Figure 8)

OPERATION (continued)
FIGURE 9
FIGURE 10
The Fume Arms have two adjustment points that can be
changed at any time to give the arm greater flexibility.
Friction disks, located at the base of the arm and at the
first hinge point, can be tightened or loosened with a
7/8” wrench. (Figure 9) 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. (Figure 10)

MAINTENANCE
FIGURE 11
FIGURE 12
FIGURE 13
Replacing the Filter Cartridge
The Nanofiber MERV15 cartridge filter can be pulse
cleaned multiple times before it needs to be replaced.
Prior to making a decision to replace the filter, first
follow the procedures of “Pulsing the VentBoss Series
300 Collector” - Section 600. The cartridge can also be
taken out and manually cleaned with compressed air.
When performing these cleaning operations no longer
reduces the differential pressure (restriction to airflow),
which in turn will reduce the effectiveness of the unit,
it is time to change the cartridge filter with a new
replacement filter.
The RoboVent Pro-Series uses the SnapLock Front Load
System which is a specially designed lift mechanism
and a front load track that locks the cartridge filter in
place with a single action lever.
To Replace the filter cartridge, open the filter access
door and pull up on the two SnapLock levers, (Figure
11) releasing the filter cartridge. Now the filter can
be removed. (Figure 12) Reload the new Cartridge
Filter into the Filter Cabinet. Ensure filters are aligned
correctly in the SnapLock rails, to give an air-tight seal
when the gasket is compressed. Engage the SnapLock
by pushing down on the SnapLock levers to raise the
filters into place. Close and lock the cabinet door.
Replacement filters may be ordered by calling VentBoss
Product Group at 1-855-558-VENT.
Replacing the Metal Baffle Filters
VentBoss Series 300 collectors come equipped with
three internal baffle and metal mesh filters located in
the spark arrestance plenum. To access the baffle and
metal mesh filters release the two latches located at
the top and bottom of the spark arrestance door. Pull
each filter straight out. (Figure 13).
Both spark arrestance baffles should be removed and
cleaned on a regular basis (check every two weeks). If
particulate builds up on these baffles the risk of fire in

18 VENTBOSS • SERIES 300 SPACE SAVER COLLECTORS OWNER’S MANUAL
SECTION 700
MAINTENANCE (continued)
FIGURE 14
FIGURE 15
FIGURE 16
the system is greatly increased. Typically, these baffles
should be removed and cleaned with a hot detergent
solution every month. Filters that are bent or deformed
beyond repair should be replaced. See Equipment
Specifications Sheets for ordering proper replacements.
CAUTION! DO NOT replace these baffle filters with
anything other than what was originally installed in your
unit. Failure to do so will greatly increase the risk of fire.
Placement of the first layer baffle filter is extremely
important as the baffles should run vertical with cup side
facing the direction the air is flowing from. Failure to
place the baffle as shown will increase the risk of fire.
Particulate Removal (Cleaning)
The dust containment area is located immediately
below the cartridge filter and can be accessed through
the filter door. Cleaning frequency of the dust bin will
vary depending on the welding situation and use.
Periodically check the bin for particulate. When 2-3
inches of dust forms at the bottom of the bin remove
with a vacuum or brush and pan. (Figure 14)
Blower Maintenance
The motor and blower in your VentBoss Series 300 unit
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. (Figure 15) Installation of a new blower wheel
requires a certified VentBoss Technician to balance the
wheel and motor. Contact 1.855.558.VENT.
Solenoid Valve Maintenance
The Pulse Solenoid is located in the rear of the Motor
Plenum. (Figure 16) Under normal conditions, the pulse
valve will last for the life of the collector. Clean, dry
compressed air, at 85 PSI, will help towards a long,
maintenance free life of the solenoid. (See Specifications
Sheet for replacement information)

VENTBOSS • SERIES 300 SPACE SAVER COLLECTORS OWNER’S MANUAL 19
SECTION 800
TROUBLESHOOTING
The VentBoss Series 300 Collector is making excessive noise. Check the following:
1. Make sure the blower wheel is not hitting against the bottom filter plate.
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 85 PSI
maximum.
3. Check diaphragm on solenoid valve. If the correct pressure is supplied to the air tank
then a problem may exist with the solenoid diaphragm. See Specifications Sheet 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 VentBoss Series 300 Collector” 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.
3. 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 desk 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.
