Operation
During normal operation, dust-laden air enters the unit
through the dirty-air inlet. Airflow is directed downward
through the collector and heavier particulate falls
directly into the hopper. The cartridges remove fine
particulate and clean, filtered air passes through the
cartridge to the clean-air plenum and discharges through
the clean-air outlet.

Filter cleaning is completed using pulse-jet technology.
A solenoid and air diaphragm valve aligned to each filter
provides the pulse cleaning. The cleaning sequence
starts at the top filter and continues down through each
filter. Remove, inspect, or change the filter cartridges
from outside the unit by removing the filter access cover
and sliding the filter out.
