Product Introduction:

To reduce the frictional resistance between moving parts in the engine and minimize component wear, engine oil is continuously delivered to the friction surfaces of various moving parts, forming a lubricating oil film for lubrication. Engine oil inherently contains a certain amount of gums, impurities, moisture, and additives. During engine operation, the introduction of metal debris, contaminants from the air, and the generation of oil oxidation products gradually increase the impurities in the oil. If the oil is not filtered and directly enters the lubrication circuit, the impurities contained in the oil will be carried into the friction surfaces of moving pairs, accelerating component wear and reducing the engine's service life.

Due to the high viscosity of engine oil and the elevated impurity content, oil filters generally employ a three-stage system to improve filtration efficiency: the oil suction filter, the oil coarse filter, and the oil fine filter. The suction filter is installed in the oil pan before the oil pump and typically uses a metal mesh design. The oil coarse filter is installed after the oil pump and is connected in series with the main oil passage. It mainly includes metal scraper types, sawdust filter element types, and microporous filter paper types, with the microporous filter paper type being the most commonly used today. The oil fine filter is installed after the oil pump and connected in parallel with the main oil passage. It primarily includes microporous filter paper types and rotor types. The rotor-type oil fine filter uses centrifugal filtration, eliminating the need for a filter element and effectively resolving the conflict between oil flow and filtration efficiency.
