The air cleaner is composed of a filter core and a shell. The main requirements of air filter are high filtration efficiency, low flow resistance, can be used for a long time without maintenance.

Air Filter is mainly used in the fields of pneumatic machinery, internal combustion machinery and so on. Its role is to provide clean Air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling Air with impurity particles in the work and increase the probability of abrasion and damage. The main components of the air filter are the filter element and the casing, in which the filter element is the main filter part, which undertakes the filtration of gas, and the casing is the external structure that provides the necessary protection for the filter element. The work requirement of air filter is to be able to undertake high efficiency air filtration work, do not increase too much resistance for air flow, and can work continuously for a long time.

It also has different degrees of application in the hydraulic system of hydraulic machinery, mainly used to adjust the pressure difference between inside and outside the oil tank of the hydraulic system.
