Working Principle of Process Bag Filter

Dust laden air enters the dust collector through the hopper or casting depending upon the application. An internal baffle distributes the dirty air within the housing, dust laden air slows down as it enters the collector, coarser dust particles drop into the hopper.

The dirty air passes through the bags, dust is captured and collected on the bag exterior. Filtered clean air flows to the clean air chamber and exhausts through the outlet. Periodic compressed air pulsing removes accumulated dust from the bags with cleaning frequency and duration adjusted by solid-state timers or PLC. Dust falls into the hopper for collection through the discharge device.
