Working Principle:
After being filtered, the dust in the air is absorbed on the high-efficiency filter cartridge and the process of back flushing and self-cleaning is done according to the set time sequence by PLC. When the loss of resistance exceeds 500 Pa, the process of back flushing (the time for back flushing is 0.1-0.2 sec) and self-cleaning is controlled by PLC according to the differential pressure sequence. Other high-efficiency filter cartridge will work as normal and the dust is back flushed.
Technical Features:
Self-cleaning air filter consists of four parts: filter component (filter cartridge), pulse self-cleaning system, high pressure back flushing cleaning device and control system. It is suitable to be used in the foggy or nasty rain seasons, open-air ice weather in winter and the desert environment full of dust. Compared with the traditional bag filter, it has stronger self-cleaning effect and the advantages of anti-moisture, anti-freezing and small resistance.
