The air filter (Air Filter) is mainly used in the fields of pneumatic machinery and internal combustion machinery. The function is to provide clean air for these machines in order to prevent the mechanical equipment from inhaling air with impurity particles in work and increasing the probability of abrasion and damage. The main component of the air filter is the filter core and the shell, in which the filter core is the main filter part and carries the filtering work of the gas, and the shell is the external structure to provide the necessary protection for the filter core. The working requirements of air filters are high efficiency air filtration, excessive resistance to air flow and long continuous work.
It also has different degrees of application in the hydraulic system of hydraulic machinery, which is mainly used to regulate the pressure difference between the inside and outside of the hydraulic system.
