What Is The Structure Of A Compressed Air Filter?

The compressed air filter consists of a filter cartridge, a clean air chamber, a pulse self-cleaning compressed air piping, an air intake protection net, a skirt, a steel frame, an electric controller, a PLC, etc. Under the action of the negative pressure of the compressor suction, the self-cleaning air filter inhales the surrounding air. Due to the combined effects of gravity, static electricity, contact resistance, inertial diffusion, etc., the dust in the air is deposited on the outer surface of the filter cartridge filter material. The clean air converges in the clean air chamber and enters the compressor through the outlet pipe. When the PLC issues a self-cleaning command, the solenoid valve will open instantly for about 0.1~0.2 seconds, sending out a pulse airflow, and blowing off the dust on the outer surface of the filter cartridge through the action of injection and backblowing. This backblowing self-cleaning process is intermittent, and only three to four filter cartridges are in the backblowing self-cleaning state each time, and the rest of the cartridges are still working. Therefore, the self-cleaning air filter has an online self-cleaning function to ensure the continuous operation of the air compressor. The self-cleaning air filter has three cleaning modes: pressure difference, timing, and manual. The self-cleaning mode is selected and set on the controller.
