Common causes of screw air compressor oil clogging failure:

1. The surrounding environment of the screw air compressor. There are corrosive gases in the surrounding environment of the screw air compressor. For example, in some occasions, sulfide, thinner, cleaning chemicals, etc. will volatilize in the air. The high temperature of the machine itself will accelerate the oxidation of the oil. Once these gases Entering the screw air compressor system, there is a chemical reaction with the engine oil, resulting in carbon deposits and sludge, etc. Some of the impurities enter the oil circulation system and are intercepted by the oil filter, and the other part of the impurities rises to the oil with the oil-gas mixture. When the gas passes through the oil, these Impurities stay on the oil filter paper, block the filter holes, and increase the resistance of the oil, so that the oil needs to be replaced in a short period of time.

2. Qualified air filter, oil filter, and engine oil are not used, one or more of them exist. The air filter with poor filtration accuracy will prevent some dust particles in the air from being intercepted, and will directly enter the screw air compressor system, and the oil filter and oil component load will be too large, resulting in blockage; impurities and oil oxides entering the screw air compressor system , worn metal particles, etc. Due to the poor filtration accuracy of the oil filter, a part of the intercepted oil filter filter layer, another part of the impurities has been continuously in the machine until it rises to the oil, and stays in the filter layer of the oil after separation, causing the oil to be removed prematurely. Blockage: engine oil with poor oxidation resistance should not be used, even if the working time is short, it will produce carbon deposits and jelly, which will block the oil.

3. There is leakage on the pipeline between the air filter and the air inlet of the main engine. The common causes of leakage are: the air filter is not installed properly; the contact area of the air filter assembly is uneven; the contact surface between the air filter and the assembly has dirt attached to it, resulting in leakage; ; Air filter or air filter assembly rupture, etc.

4. Excessive moisture in the oil filter material will cause the filter material to swell and shrink, reducing the effective separation area of the oil, resulting in an increase in the resistance of the oil and premature blockage of the oil
 

Tips:
This is only a part of the part numbers, many oil separator filters P/N are not listed, in addition there are replacements filters for many other air compressor brands.
