Collector Operation
Operation
During normal operation, dust-laden air enters the
collector through the top 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.
An air diaphragm valve aligned to each filter provides
the pulse cleaning. Either a manual push-button valve or
electronic solenoid valve actuates 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 collector by
removing the filter access cover and sliding the filter out.

Information
General rating and specification information can be
found in the product literature provided with the collector
