Timer activated solenoid valves release short blasts of air inside cartridge filters causing dust build-up to fall into the hopper. This hopper is configured with a non-flow-through pick-up adapter for negative-pressure pneumatic conveyor lines. Other configurations allow connection to flexible screw conveyors or other conveyors and process equipment.
Filters are accessed easily by removing the interior baffle, and replaced rapidly using quick-disconnect fittings.
