This series of portable ventilation blowers has been designed for industrial heavy duty
applications in confined space ventilation. These blowers are the primary tool for providing
fresh clean ventilation air to remote work locations. Each work environment should be
thoroughly evaluated by a competent person before selecting the proper blower for a par-
ticularapplication.
SAFETYPRECAUTIONS:

GENERAL SETUP & OPERATION, ELECTRIC BLOWER SERIES
MODELS SVB-E8, SVB-E8-2, & SVB-E8EC
STEP1)
Place blower in a clean fresh air environment. 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 confined space should be tested prior to ventilation. If air
qualityof the confined space is unacceptable, consult a trained professional.
STEP2)
Installductcuff toexhaustflangeand tightencinchstrap. Keepbends andkinksinducting toa
minimumtomaximizeairflow.
STEP3)
Connectto120VAC, 15 amp, 60Hz dedicated service. All standard electric blowers listed are
suppliedwithGFI plug (GroundFaultInterrupters)perthe 1996NECcoderequirement: Section
305-6.
Note: If an extension cord is required, the minimum recommended size is 12 AWG
(Maximum 100 ft.). For further information, refer to the National Electric Code Tables,
Article 400. (The use of generators are not recommended unless they are of sufficient
output capacity. Some generator’s output current will not allow the use of GFI plugs. A
standard 3-prong plug would need to be installed instead of the GFI recepticle).
STEP 4) Push “on/off” (reset) switch, located on the GFI unit, to the “on” position. The
unitisnowoperational.
SHUTDOWN
• Insurethatallworkers are removedfromthe confinedspacesite.
• Shutoff blowerandremoveallducting.
MAINTENANCE
• Keep blower motor dry and free from contaminants and dust.
• Check periodically to ensure moving parts are free from obstructions.

GENERAL SETUP & OPERATION, EXPLOSION-PROOF ELECTRIC BLOWER
MODEL SVB-E8EXP
STEP1)
Place blower in a clean fresh air environment. 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.
CAUTION:
Air quality of the confined space should be tested prior to ventilation. If air quality of the
confined space is unacceptable, consult a trained professional.
STEP 2)
Install duct cuff to exhaust flange and tighten cinch strap. Keep bends and kinks in ducting
to a minimum to maximize air flow. THE USE OF CONDUCTIVE DUCTING IS REC-
OMMENDED WHEN OPERATING IN POTENTIALLY EXPLOSIVE ENVIRON-
MENTS.
STEP3)
Explosion-proofmodelsshouldbe fitted with anapprovedexplosion-proof plugtomeet Class I, Div.I,Groups C and D,
ClassII,Div. I, Groups E,F,Gspecifications. Theplugshould not be disconnectedorconnectedin an explosive environ-
mentwhen theblowerisenergized.
STEP 4) Switch the explosion-proof “on/off” switch to the “on” position. The unit is now operational.
SHUTDOWN
• Insure that all workers are removed from the confined space site.
• Shut off blower and remove all ducting.
MAINTENANCE
• Keep blower motor dry and free from contaminants and dust.
• Check periodically to ensure moving parts are free from obstructions.
CAUTION:

SHUTDOWN
• Insurethatall workers areremovedfromthe confined spacesite.
• Shut off blower and remove all ducting.
MAINTENANCE
• Keep blower motor dry and free from contaminants and dust.
• Check periodically to ensure moving parts are free from obstructions.
•Change filter (Part# WL040B) located in regulator after approximately 300 - 500 hours
• UseSAE#10 automotiveengineoilor lighterinlubricatorat alltimes. (Donotexceed 10weightoil). Heavy
weightoils willcausedamage totheairmotor.
• Cleanmufflerassembly every100-300hourswith safetysolvent(Part#BAC-1001).
• Flushairmotor every100hourswith safetysolvent(#BAC-1001)through maintenanceport(seebelow).
• Remove air exhaust filter before flushing and reinstall after several minutes of running unit. Flush unit
after every 200 hours or after storing for long periods.
AIR MOTOR FLUSHING PROCEDURE
Use Air Systems’ Part #BAC-1001 safety solvent.
Do not use a flammable solvent or a solvent with a toxicity rating of 500ppm or
greater to flush the unit.
Note: Eye protection should be worn when flushing the unit.

PROBLEM POSSIBLE CAUSE SOLUTION
Blower will not start Insufficient pressure Check pressure gauge on compressed air source to
ensure proper supply pressure. Turn regulator knob
clockwise to increase air pressure to air motor and
note the gauge pressure on the regulator.
Excessive vibration Possible internal damage Turn blower off and inspect fan blades, shaft, and
housing for debris, damage, and loose screws.
Note: Never run blower for extended periods without
installing duct on the exhaust flange.
Possible external damage Turn blower off and inspect housing
Blower loses pressure Insufficient air flow or
pressure Hose with a minimum 1/2" diameter is required at 10- 100cfm delivery volume
Remove muffler housing and unscrew internal air
muffler. Clean with safety solvent and reinstall.
