Air Filter refers to the device that removes the particle impurities in the air.
Air Filter refers to the device that removes the particle impurities in the air. Pistons (internal combustion engines, air filtration, etc.), if the inhaled air contains dust and other impurities, it will exacerbate the wear of the parts, so it must be equipped with empty filtration. The air filter consists of two parts: filter element and shell. The main requirements of empty filtration are the high filtering efficiency, low flow resistance, and continuous use of continuous use without maintenance.
There are three ways: inertia, filtering and oil bath.

① inertia: Because the density of impurities is large than the density of air, when the impurities rotate with the air or turn sharply, the effect of centrifugal inertia can separate the impurities from the airflow.

② Filter: guide the air flowing through the metal filter or filter paper, etc., block impurities and adhere to the filter element.

③ Oil bath type: There is an organic oil disk at the bottom of the empty filter. The airflow is used to shock the oil rapidly, separates impurities and sticks to the oil. Essence The air flow filter element can further absorb impurities to achieve the purpose of filtering.
