With the rapid development of urbanization, but also with more and more factories in the world, the air pollution on the earth is more and more serious. Many people will buy an air filter to filter the air so that the air they breathe will be fresher. There are many types of air filters, one of which is the self-cleaning type, that is, the air filter can be automatically cleaned. Then, I will introduce you to a few domestic manufacturers of self-cleaning air filters and working principle.

Jiangsu Xingda Purification Technology Development Co.
Jiangsu Xingda Purification Technology Development Co., Ltd. is a high-tech manufacturer of filters, providing filtration products to distributors and Original Equipment Manufacturers (OEMs) around the world. We provide replacement filter cartridges for various industries and supply more than 200,000 sets of filter cartridges as components for new filtration equipment to our OEM partner customers every year. Since its inception, the company has been committed to providing high quality air filtration products to customers in the gas turbine and industrial industries.
Introduction of working principle:
The outlet of the clean air chamber of the self-cleaning air filter is connected with the inlet of the air compressor, and the processed air is sucked in from the atmosphere under negative pressure. The air passes through the filter cartridge, and the dust is blocked by the filter media. Countless small particles of dust form a dust film on the windward surface of the filter media. This film increases the filtering effect, but also increases the resistance of the airflow. When the resistance increases to the high limit of 600Pa, by the differential pressure transmitter resistance signal to the pulse controller in the computer, the computer issued a command, the self-cleaning system began to work; solenoid valve receives the command, according to the program to control and drive the diaphragm valve, the diaphragm valve instantly releases compressed air, the pressure of which is 600-800kPa, rectified by the nozzle, from the inside of the cartridge back to the cartridge, the outside surface of the filter media will be blown off the dust! Then the resistance decreases. When the resistance reaches the initial resistance of the filter media (about 150Pa), the self-cleaning system stops working.
The above is the small make up to bring you about the self-cleaning air filter related to the introduction, small introduction should bring you a lot of help, in the purchase of self-cleaning air filter you should know which brand to buy better. The air filter can filter the air automatically, you only need to plug in the electricity on it, in the air pollution is more serious city, it is best to buy an air filter placed in the factory, so as to protect the health of employees.
