The air filter element is one of the important components of the air filter of the air compressor. The air filter is the part that filters out the dust and dirt in the air. 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 be filtered out. If the air filter element is blocked and damaged, a large amount of particles larger than 15u will enter the screw machine for circulation, which will not only shorten the service life of the oil filter element and oil fine separation core, but also cause a large amount of particles to directly enter the bearing cavity, which will accelerate the bearing wear and increase the rotor gap. , the compression efficiency is reduced.

1. The air filter element is best maintained once a week, unscrew the gland nut, take out the air filter element, and use 0.2-0.4Mpa compressed air to blow out the dust particles on the outer surface of the air filter element from the inner cavity of the air filter element. Clean the dirt on the inner wall of the empty filter housing with the rag. Reinstall the air filter element, and pay attention that the sealing ring at the front end of the air filter element should fit tightly with the inner end face of the air filter housing. The maintenance of the diesel engine intake air filter element of the diesel power screw engine should be carried out simultaneously with the air compressor air filter element, and the maintenance method is the same.

2. When cleaning or replacing the air filter element, the parts must be checked one by one to prevent foreign matter from falling into the intake valve.

3. Usually, it is necessary to check whether the intake telescopic pipe is damaged or flattened, and whether the connection between the telescopic pipe and the air filter intake valve is loose or leaking. If found, it must be repaired and replaced in time.
