What is oil filter?

The oil filter is mainly used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil, thereby protecting the engine. It is a part that is frequently replaced during vehicle maintenance and plays a vital role in keeping the lubricating oil clean and the engine running normally.


Oil filter production process

The simplest oil filter production line requires these machines: Spin on Filter Seaming Machine, sealing gluing machine, Silk Screen Printing Machine and Four Station Filter Air Leakage Tester.

Oil filter working process

The oil enters the oil filter through the oil pump. There is a special filter element inside the filter, which can capture fine particles in the oil (dust, carbon deposits and tiny debris, etc.). After being filtered by the filter, the clean oil will flow back to the engine, clean the lubrication system in the engine, and maintain efficient operation.


Poor quality oil filter not only affects the normal oil supply and lubrication of the engine by the oil pump, but also the main oil channel interface may not be sealed tightly, causing oil to leak out from the joint surface between the oil filter and the cylinder body, resulting in oil leakage, poor engine heat dissipation and other faults. In serious cases, cylinder explosion may occur, so be cautious when choosing an oil filter.


What should I pay attention to when choosing an oil filter?


(1) Pay attention to the factory logo font on the surface of the oil filter


(2) There is a bypass valve inside to ensure that there is sufficient oil supply under any conditions.


(3) The complex backflow suppression design ensures that there is enough oil in the oil filter for the next start, reducing wear during cold start.


(4) There is lubricating butter at the interface, the sealing material of the gasket should be good, and the rubber parts should be regular.


(5) The metal oil mesh in the filter paper filter element has a standard shape to ensure the oil flow rate.


(6) The material density is moderate to ensure oil filtration.


Specific advantages of oil filter

Effectively filter out harmful impurities in the oil in the oil pan, protect key parts of the engine (crankshaft, connecting rod, camshaft, supercharger, etc.) from damage.

Ensure the cleanliness of the oil, provide good lubrication, cooling and cleaning for the engine, extend the service life of parts and avoid engine wear.
