During a typical operation, dust in the in-flow air is captured at the outer surface of cylindrical air filter cartridges, and the cleaned air passes the filters into the inner cavities, then converges in an air chamber and flows out.

Cleaning:
When some filter cartridges are heavily soiled, differential pressure sensors will automatically trigger the openning of diaphragm valves to let in compressed air (0.5-0.7MPa) to blow away dust on the surfaces of these cartridges. The dust, pushed by compressed air flow and gravity, goes into dust collecting hopper.
