WARNING

All ventilation procedures should comply with federal, state, and local regulations. Air quality should be tested prior to
ventilating a con ned space. A purge chart is provided on our website, www.airsystems.com, help assist in estimating the
approximate time needed to ventilate con ned spaces. Air quality should be tested continuously during con ned space
occupancy to ensure a stable atmosphere and worker safety because atmospheric conditions can change rapidly. Addi-
tional procedures and recommendations are available from federal, state, and local agencies. DO NOT operate these fan
unit in a vertical position or with the  ange or guards removed.
Note: If volatile or explosive vapors are suspected, use Air Systems’ explosion proof electric blower, Model No. SVB-
E8EXP, explosion proof in-line fan, Model No. SVF-10EXP, explosion proof contractors fan, Model No. CVF-8EXP or Air
Systems’ intrinsically safe pneumatic blower, Model No. SVB-A8.
Note: For con ned space ventilation in non-hazardous locations, use Air Systems’ con ned space ventilation kit, Model
SV-CUP. For hazardous locations use ventilation kit, Model SV-CUPCND along with one of the above explosion proof
blowers or fans.

STEP 1)
Operate blower in shown position only. Place in a clean fresh air environment away from
toxic gases and dust. Set blower a minimum of 5 ft. from the manhole opening.
Note: Inspect blower for damaged or worn parts. Inspect all ducting and couplings
for possible air leaks prior to blower operation.
Note: Air quality of the conned space should be tested prior to ventilation. If air
quality of the conned space is unacceptable, consult a trained professional.
STEP 4)
Install duct cuff to exhaust ange and tighten cinch strap. Keep bends and kinks in ducting
to a minimum to maximize air ow. The use of conductive ducting is recommended
when operating in potentially explosive environments. Assure that the blower is
properly grounded before operating and that the ground wires from the conductive
ducting and Saddle Vent®, if used, are securely attached to the blower’s grounding
wire.
STEP 2)
Attach and tighten the lter/regulator and lubricator assembly. Make sure oil level in the
lubricator is at the full mark (approximately 3/4 of bowl height); add additional oil if neces-
sary. Factory recommended oil is #F44200 Parker tool oil,
viscosity 100 or higher, mineral oil base, (Sunvis #932 or equivalant).
STEP 3)
Secure a primary air source with a ow capacity of 10–100cfm and a pressure range of 10
–100psi. Attach a minimum 1/2” I.D hose to the inlet tting. Note: Maximum inlet pres–
sure should not exceed 150psi (10 bar).
CAUTION:
If explosive or volatile vapors are suspected or present,
follow ANSI/API procedure 2015 and 2016 for proper
grounding of the blower. All static electricity must be
removed from the blower and attached ducting prior to
energizing the blower. Conductive ducting should be
tested semi-annually to assure resistance (ohms) does not
exceed 300k. If sufcient resistance is not achieved, the
duct should be removed from service.

General Setup & Operation
Model: SVB-A8

STEP 5)
Adjust pressure regulator clockwise to increase, counterclockwise to decrease motor
speed. This adjustment will increase or decrease the air ow.
Note: Available air pressure (psi) and volume (cfm) will determine blower
performance.
STEP 6)
The proper amount of oil mist has already been factory preset. However, depending on
the viscosity of the oil being used, slight adjustments may be necessary. With the blow-
er running, the proper oil mist should be one drop/min. The oil mist adjustment screw is
located next to the oil ll cap. Turn this screw clockwise to decrease or counterclockwise
to increase oil ow.
Note: Approximately 1 drop per minute can be achieved by turning the adjust-
ment screw fully clockwise, then counterclockwise 1 1/2 turns.
