The air filter provides clean air to the engine (internal combustion engine, reciprocating compressor, etc.) to prevent the engine from inhaling air with impurity particles during operation, and increase the valve, cylinder working surface, piston ring, bearing bush and other engine The probability of parts abrasion and damage. The air filter is mainly responsible for the filtration of high-efficiency gas, reducing the resistance of air flow, and can work continuously for a long time, and can effectively reduce fuel consumption.

The air-conditioning filter can effectively filter the air that enters the cabin from the outside to improve the cleanliness of the air, and filter the impurities contained in the air, such as tiny particles, pollen, bacteria, industrial waste gas and dust. The pleated shape design can provide a long service life. The lower flow resistance can minimize blower burden. The filter element is tightly fitted to the housing to prevent air from bypassing.

The oil filter can minimize the friction generated by the components during operation, reduce energy loss and parts wear. The oil filter removes impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine.

The main materials are high-quality materials of international brands and domestic joint venture brands, of which the filter materials are imported from South Korea Oslon Ahlstrom, American Hollingsworth & Vose, German Gesno Gessner and other imported filter materials and domestic high-quality filter materials, and the filter paper is thermally cured. Reliable removal of contaminants. Because the fuel system uses high quality filter media, it can be protected from very small pollutants, so it will not be damaged by corrosion. This not only protects the engine, but also ensures the efficient operation of the vehicle. By adjusting the pressure and by re-circulating the excess fuel from the injection pump to the tank, the required stability of the fuel supply is finally achieved.
