Function and industry standard of filter element


Filter element is a professional term in the filtration industry. In order to purify the original ecological resources and reuse resources, it needs purification equipment. Now the filter element is mainly used in oil filtration, air filtration, water filtration, air filtration and other filtration industries. It is used to remove a small amount of solid particles in the liquid or air, which can protect the normal operation of the equipment or the cleanness of the air. When the fluid enters the filter element with a certain specification filter screen, its impurities are blocked, and the clean flow flows out through the filter element. The liquid filter element makes the liquid (including oil, water, etc.) clean to the state required by production and life, that is, to make the liquid reach a certain cleanliness.

Air makes the polluted air clean to the state required by production and life, that is, to make the air reach a certain cleanliness.
