The mobile fume extraction unit is mostly used to filter the gas, which is called the air filter cartridge (hereinafter referred to as the filter cartridge). The filter cartridge belongs to the surface filter element, which uses the tiny air-permeable tissue formed on the surface of the filter material to block the particulate matter in the gas.

The automatic cleaning method commonly used in mobile fume extraction unit includes high-pressure gas pulse back blowing mechanical vibration. Pulse backflushing is to use the preset parameters of the controller to give the solenoid valve a signal to instantly open and close the solenoid valve diaphragm, so that the high-pressure gas enters the injection pipe and uses the rapid expansion force of the gas to shake off the dust on the surface of the filter cartridge. General gas pressure we set It is about 6 kg force. Mechanical vibration cleaning is often used in small single-machine filter cartridge dust collectors. It uses the shaking force generated by the eccentric device on the dust collector's flower plate to clean the dust. This action needs to be stopped and operated.
