The air filter is a component of screw air compressor that filters out air dust and dirt, and the filtered air enters the compression chamber of the screw rotor for compression. The internal clearance of the screw air compressor machine only allows particles within 15u to be filtered out.
If the air filter system of screw air compressor is blocked and damaged, a large number of particles that is larger than 15u will enter the screw air compressor machine. this will not only greatly shorten the service life of the oil filter, the oil and gas separator, but also a large number of particles directly enter the bearing cavity, the bearing will wear fast and the rotor gap increasing. The compression efficiency reduces, the worst is that it will be hard for the rotor to do the compression job.
The oil filter system of screw air compressor should be replaced after 500 hours of working for the first time, the oil filter system should be removed with a special wrench. It is better to refill the coolant for screw air compressor before replacing old new filter system. Screw the filter system back to the oil filter seat with both hands and tighten it firmly.

It is suggested to replace the new oil filter system of screw air compressor every 1500-2000 hours. It is best to change the coolant when changing the oil filter system. The replacement of oil filter system should be shortened when the environment is bad. It is strictly forbidden to use the oil filter system beyond the time limit. Otherwise, the oil filter system is seriously blocked and the pressure difference exceeds the limitation of the valve, the valve will automatically open. A large amount of dirt particles will directly enter the screw host of screw air compressor machine and causes serious problems.
Parts of oil and gas separator of screw air compressor
The oil and air separator is a component that separates the coolant of the screw air compressor machine and the compressed air. Under normal operation, the life of the oil-air separator is around 3000 hours, but the quality of lubricating oil and the cleanness of the frittered air has a huge impact on its life. It is clear that the maintenance and replacement of the air filter system must be shortened in a harsh environment, and the installation of a front air filter is needed. The oil and gas separator must be replaced when it is needed or the pressure difference between the front and back is over 0.12Mpa. Otherwise, the motor will be overloaded and the oil and gas separator will be damaged and leak.
