Compressed Air Connections
2.9.1
Attach a flex hose and dust drum lid to the bottom
of the dust hopper.
CAUTION
The air source for the filter pulse must be 35 to
50 degrees Fahrenheit dew point and be free of
any oil contaminants. If line air does not meet
this requirement, an optional air dryer is
recommended. Moisture or oil contaminants in
the pulse system will decrease cartridge life
and filtering efficiency
2.9.2
Place a dust drum under the dust lid and
securely attach the lid to the drum.
CAUTION
All flex hose connections made at the bottom of
the hopper and the lid must be air tight.
2.8.1
An air line must be supplied to the pressure
regulator located on the pulse manifold inlet. The size of
the line depends on the size of the collector. The
compressor and piping supplying air to the pulse
manifold must be large enough to provide at least 3 cfm
per cartridge. The air line should not be smaller in
diameter than the manifold inlet at the regulator.
3.0 OPERATION
WARNING
All persons operating this equipment must be
made aware of the hazards of abrasive blasting,
and handling toxic materials, including red lead
and silica dust. Toxicity and health risk vary
with the type of media, and dust generated by
blasting. Identify all material being removed by
blasting, and obtain a materials safety data
sheet for the blast media.
2.8.2
Purge the air supply line to remove moisture or
other foreign material before connecting it to the pulse
manifold.
2.8.3
Connect tubing to the differential pressure
indication panel as shown in Figures 1 and 3.

The dust collector access covers must be
closed, and the dust drums secure when the dust
collector is in operation.
3.2 Initial
Start-up
WARNING
Do not look into the exhauster outlet while the
fan is turning. Injury to the eye or face could
occur from objects being ejected from the
exhauster.
3.2.1
Check motor rotation by jogging the starter
(momentarily turn switch on and off). This will cause the
motor to rotate slowly. Look through the slots in the fan
housing on the end of the motor where rotation of the
fan can easily be observed. Proper rotation is indicated
by the arrow on the exhauster housing. The fan should
rotate toward the scroll.
