Model Svb-A8 - AIR SYSTEMS INTERNATIONAL SVB-E8 Manuel D'utilisation

GENERAL SETUP & OPERATION, PNEUMATIC BLOWER

MODEL SVB-A8

STEP 1)
Operate blower in vertical 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 confined space should be tested prior to ventilation. If air qual-
ity of the confined space is unacceptable, consult a trained professional.
STEP 2)
Attach and tighten the filter/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 necessary. Factory
recommended oil is SAE #10 automotive engine oil or lighter. (Petroleum based only, do not use
synthetic oils.)
STEP 3)
Secure a primary air source with a flow capacity of 10 - 100cfm and a pressure range of 10 -
100psi. Attach a minimum 1/2" I.D hose to the inlet fitting. Note: Maximum inlet pressure should
not exceed 150psi (10 bar).
STEP 4)
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 RECOM-
MENDED WHEN OPERATING IN POTENTIALLY EXPLOSIVE ENVIRONMENTS.
Assure that the blower is properly grounded before operating and that the grounding wires
from the ducting and Saddle Vent
ing wire.

STEP 5)
Adjust pressure regulator, clockwise to increase, counterclockwise to decrease motor
speed. This adjustment will increase or decrease the air flow. Note: Available air
pressure (psi) and volume (cfm) will determine blower performance.

If explosive or volatile vapors are suspected or present, follow ANSI/
API 2015 and 2016 procedures 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 semiannually to assure resistance
(ohms) does not exceed 300k. If sufficient resistance is not achieved,
the duct should be removed from service.
