I. The surrounding environment of the air compressor.

   The surrounding environment of the air compressor contains corrosive gases, as sulfides, thinners, and cleaning chemicals that volatilize in the air. The high temperature of the machine accelerates the oxidation of the oil Once these gases enter the air compressor system and react chemically with the oil, they produce carbon deposits and sludge. Some of these impurities are intercepted by oil filter in the oil circulation system, while the rest rise with the oil-gas mixture to the oil separator. As the gas passes through the oil separator, impurities stay on the filter paper of the oil separator, blocking the filter holes. The resistance of the oil separator gradually increases, leading to the need for early of the oil separator within a short period of time.

II. Use of unqualified air filters, oil filters, and oil, either singly or in combination   Air filters with poor filtration accuracy allow some dust particles in the air to pass through, directly entering the air compressor system. This overloads the oil filter and separator, causing blockages. The impurities entering the air compressor system, along with oil oxidation products and worn metal particles, are not fully intercepted by the oil due to its poor filtration accuracy. Some are intercepted on the oil filter's filter layer, while the rest continue to circulate within the machine until they rise to oil separator. After separation, they stay on the filter layer of the oil separator, leading to early blockage of the oil separator. Oil with poor antioxidant properties not be used, as it can produce carbon deposits and gummy substances even with short working times, blocking the oil separator.

III. Leakage in the piping the air filter and the main unit's air inlet.

   Common causes of leakage include: improper installation of the air filter; uneven contact area of the air filter; dirt on the contact surface between the air filter and the assembly, causing leakage; the elastic contact pad on the air filter is misaligned; the air filter air filter assembly is cracked, etc.

IV. Excessive moisture on the oil separator filter material causes it to swell and the micropores to contract, the effective separation area of the oil separator, leading to increased resistance and early blockage of the oil separator.
