Operation
During normal operation, dust-laden air enters the
collector 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 diaphragm valve aligned to each row
of filters provides the pulse cleaning. The cleaning
sequence starts at the top filter row and continues down
through each module. Remove, inspect, or change the
cartridges from outside the collector by removing the
filter access cover and sliding the filters out.
