Key Functions of an Oil Filter:
Filtering solid particles and preventing wear: This is the most basic and important function of an oil filter. It uses filter media (such as fiberglass, stainless steel mesh, and filter paper) to physically block and adsorb suspended solid particles in the oil.
Controlling oil cleanliness and extending oil life: Oil filters protect not only equipment but also the oil itself.
Protecting downstream precision components and ensuring system response accuracy: In modern hydraulic systems and high-pressure common rail engines, the clearance between the valve core and valve body can be as small as 3-5 micrometers.
