The introduction of  air filter:

Donaldson air filter is mainly used to filter the dust, impurities, particulate matter and other harmful substances in the air. There are not many applications in life. In order to ensure the cleanliness of equipment in the industrial machinery industry, Donaldson air filter is usually used to filter air.

The processing raw material of Donaldson air filter element is domestically made or coated polyester non-woven fabric. This fabric has the characteristics of waterproof, anti-static, oil discharge and non-combustible. It is processed by advanced processing equipment and foreign advanced wide pleat discount technology. . The end caps at both ends of the Donaldson filter element are made of anti-rust steel plates with a thickness of more than 8mm through strong pressure, which effectively ensures the tightness and seamless gap between the end cap and the filter material. The inner and outer support and protection framework of the filter cartridge is made of punched stainless steel with high strength and good corrosion resistance above 5mm. The inner and outer guard nets and inner filter material of the filter cartridge are processed using international advanced glue fixing technology to ensure the performance of the filter cartridge.
