How to classify the filter element of air filter? What are the characteristics of each?

Everyone knows that an air filter is a device to remove particles and impurities from the air. What are their characteristics? Following hongfeng xiaobian to understand:

The filter elements of the air filter are divided into dry filter elements and wet filter elements. The dry filter core material is filter paper or non-woven cloth. In order to increase the air through the area, the filter element is mostly processed into many small folds. When the filter element is slightly damaged, the compressed air can be used to blow it clean. When the filter element is seriously damaged, the new core should be replaced in time.

The wet filter element is made of sponge type polyurethane material. When installed, some oil should be added and kneaded by hand to absorb foreign bodies in the air. If the filter element is damaged, it can be cleaned with cleaning oil. Excessive damage should also be replaced with a new filter element.

If the filter block is serious, it will increase the intake resistance and reduce the engine power. At the same time, due to the increase in air resistance, will increase the amount of gasoline absorbed, resulting in the mixing ratio is too thick, so that the engine running state is bad, increase fuel consumption, but also easy to produce carbon. Usually should develop the habit of checking air filter element often.
