Oil filter is located in the engine lubrication system. It is oil pump upstream, downstream is need lubricating parts in the engine. The role of harmful impurities in the oil from the oil pan filter, crankshaft, connecting rod, CAM shaft to clean the oil supply, turbocharger, piston ring, such as motion pair, lubrication, cooling and cleaning effect, so as to prolong the life of these parts.

Fuel filter is the filter engine fuel gas system the harmful particles and water, in order to protect the pump nozzle, cylinder liner, piston ring, etc., to reduce wear and avoid congestion. The containing iron oxide in the fuel oil, dust and other solid impurities removed, to prevent the fuel system block (especially the nozzle). To reduce mechanical wear and ensure the stable operation of engine, and improve the reliability.

Air filter is located in the engine air intake system, it is composed of one or a few clean air filter of parts assembly. Its main role is filter will enter in the air cylinder harmful impurities, to reduce the cylinder, piston, piston ring, valve and valve seat early wear.

Environmental protection filter only hand tighten or twist when loading and unloading, without tools, simple and convenient. Realize the effective utilization of resources and energy, reduce the discharge of harmful substances. Improve the performance of the filter itself and the filter area.
