The outlet of the clean air chamber of the self-cleaning filter is connected to the inlet of the air compressor. Under the action of negative pressure, the process air is sucked in from the atmosphere. The air of the self-cleaning filter passes through the filter cartridge, and the dust is blocked by the filter material. Countless small particles of dust form a dust film on the windward surface of the filter material.

The dust-proof film can improve the filtering effect of the self-cleaning filter and increase the airflow resistance. When the resistance increases to the upper limit of 600Pa, the differential pressure transmitter sends the resistance signal to the computer in the pulse controller, and the computer issues instructions and the self-cleaning system starts to work. After the self-cleaning filter receives the command, the solenoid valve controls and drives the diaphragm valve according to the program, and the diaphragm valve immediately releases the compressed air with a pressure of 600-800kPa. After the correction by the nozzle, the filter cartridge is blown back from the inside of the filter cartridge to blow away the dust on the outer surface of the filter material, and the resistance is reduced. When the resistance reaches the initial resistance of the filter material (about 150Pa), the self-cleaning filter self-cleaning system will stop working.

Various types of compressed air stations in various industries are especially suitable for multi-stage centrifugal, screw and vane air compressors. Small capacity can be multi-machine with a large capacity with a self-cleaning filter is appropriate;

1. Blast furnace steel plant induced draft fan;

2. Compressor inlet of oxygen generator; Self-cleaning filter

3. Gas turbines and diesel engines of various capacities;

4. Chemical fiber textile electronics industry air conditioning system;

5. Centralized air conditioning system requires high dust content in the air;

6. Air conditioning systems for the tobacco and paper industries. Self-cleaning filter
