Replace atlas Copco compressor oil filter 1621737800

How to distinguish the pros and cons of oil filter:

1. Appearance: fine and rough in appearance

The fake oil filter has rough printing on the surface of the casing, and the font is usually blurred. The factory logo font on the surface of the real oil filter is very clear, and the surface paint texture is very good. Careful friends can easily see the difference through comparison.

2. Filter paper: the filter capacity

The fake oil filter has poor ability to filter impurities, which is mainly reflected in the filter paper. If the filter paper is too dense, it will affect the normal flow of oil; if the filter paper is too loose, a large number of unfiltered impurities will continue to flow randomly in the oil. Causes dry friction or excessive wear of engine internal parts.

3. Bypass valve: the auxiliary function

The function of the bypass valve is a device used to transport oil in an emergency when the filter paper is blocked due to excessive impurities. However, the built-in bypass valve of most fake oil filters is not obvious, so when the filter paper fails, the oil cannot be delivered in time, which will cause dry friction of some parts in the engine.

4. Gaskets: sealing and oil seepage

Although the gasket looks a little inconspicuous, the sealing between parts depends on it. The gasket material in the fake oil filter is relatively poor, and it is likely to cause its sealing failure under the high temperature and strength of the engine, resulting in oil leakage.
