Maintenance and maintenance of screw air compressor

1. Maintenance and maintenance of intake air filter element. The air filter is a component that filters air dust and dirt, and the filtered clean air enters the compression chamber of the screw rotor for compression. Because the internal clearance of the screw machine only allows particles within 15u to filter out.
