Air purifier to remove particles of impurities in the piston mechanical work, if inhaled air contains dust and other magazines will exacerbate the wear and tear parts, it must be equipped with air filters.

Air filter by the filter and the shell of two parts, its main requirements are high filtration efficiency, low flow resistance, can be used continuously for a long time without maintenance.

Air filters are mainly used in the fields of pneumatic machinery and internal combustion machinery to provide clean air for these machinery and equipment to prevent the mechanical equipment from inhaling air with impurity particles during operation to increase the chance of abrasion and damage. Air filter is the main component of the filter and chassis, in which the filter is the main part of the filter, bear the gas filtration, and the chassis is to provide the necessary protection for the filter outer structure. The working requirement of the air filter is to be able to carry out high efficiency air filtration without adding excessive resistance to air flow and can work continuously for a long time.

Its hydraulic system in the hydraulic machinery also have different levels of application, mainly used to adjust the hydraulic system, the pressure difference between the inside and outside the tank.
