FAQ

Q: How do cartridge oil filters work?

The cartridge oil filter is its core filtering component, which mainly removes impurities from the oil through physical interception. Its working principle is as follows:
Oil inflow: When the engine is running, the oil pump presses the oil in the oil pan into the filter, and under the action of oil pressure, pushes open the check valve, and the oil enters the outside of the filter paper.
Impurity interception: Engine oil passes through filter paper (usually folded from multi-layer resin treated microporous filter paper) under pressure, while metal debris, dust, carbon deposits, and other impurities are trapped on the outer surface of the filter paper.
Clean oil outflow: The filtered clean oil enters the engine lubrication system through the central pipe, providing lubrication and cooling for various moving parts.

Key auxiliary mechanisms

Bypass valve: When the filter paper is severely clogged due to impurities or the oil viscosity is too high (such as during cold start), the bypass valve automatically opens, allowing unfiltered oil to enter the engine directly, avoiding serious wear caused by lack of oil.
Check valve: After the engine is turned off, it closes to prevent filtered oil from flowing back to the oil pan, ensuring that there is still oil in the filter element during the next start and achieving rapid lubrication.

Characteristics of filter paper
Using special filter paper with high porosity and high temperature resistance (0-300 ℃), it can effectively intercept impurities with small particle sizes (such as 0.001mm or more).
However, due to material and structure limitations, the actual filtration efficiency is limited: even high-quality filter cartridges can only filter out about 60% of impurities, making it difficult to completely remove ferromagnetic particles and other impurities.

In summary, the paper core achieves purification through precision pore mechanical filtration, and is equipped with safety mechanisms such as bypass valves to ensure both filtration efficiency and engine lubrication safety.

Q: What is the purpose of a cartridge oil filter?

The cartridge oil filter is the core filtering component in the engine lubrication system, and its main uses are as follows:
• Filter impurities: intercept harmful substances such as metal debris, carbon deposits, gum, dust, and moisture in the engine oil to prevent these impurities from circulating with the oil and exacerbating internal engine wear.
• Ensure lubrication effect: Provide clean engine oil to key moving parts such as crankshafts, connecting rods, camshafts, piston rings, and superchargers to ensure proper lubrication, cooling, and cleaning functions.
• Extend engine life: By continuously and efficiently filtering, reducing component wear and reducing the risk of failure, the overall service life of the engine is extended.

Q: What to soak a cartridge filter in?

Cartridge filters for hydraulic systems or industrial fluids:
This type of filter is usually filtering oil or hydraulic media. The filter element is disposable and cannot clean after blockage. It needs to be replaced directly and soaking is not recommended. It should be replaced periodically.
