Installation considerations
1. The seals should be placed correctly and should have electrostatic conductivity measures, and the oil-resistant seals can work normally at a high temperature of 120 ℃.
2. For vertically installed external intake oil, the oil return pipe must be long enough, and it should be placed directly into the oil, reaching the recess on the inclined surface of the bottom end cover.   
3. Select high-quality lubricating oil. The lubricating oil system should not be mixed with any foreign matter, and the oil should be replaced regularly.
4. When installing the formal screw-in oil-gas separator, the oil return pipe must be placed at the bottom of the separator. 

The oil separation pressure difference rises too fast
The oil separation pressure difference is formed when solid particles in the compressed air are trapped in the oil separation core filter layer.
1. Air filters and oil filters for air compressors have a certain life, and they must be replaced on time. Low-quality air filters and oil filters should not be used.
2. When the operating temperature of the compressor is high or the oil quality is low, the oil is easy to aging and oxidation, forming colloids, blocking and contaminating the filter element, causing the pressure difference to rise too fast.
3. The oil-gas separation tank of the air compressor should be drained regularly, otherwise the filter element is prone to corrosion.

Excessive fuel consumption (high exhaust gas oil content)
1. The oil return pipe is blocked or the oil return pipe does not work. In this case, a large amount of oil is stored in the oil separation core, and the oil is brought out by a large amount of gas.
2. The excessive refueling in the oil tank leads to a high oil content of the gas entering the oil separation core, and the oil separation load increases and the separation effect decreases.
3. The design of the oil tank is unreasonable, the diameter of the oil and gas drum is small, or the mechanical separation structure is poor.
4. When designing, the oil separation core is unreasonable, and the size of the oil separation core is too small, resulting in poor separation effect.
5. The seal ring and gasket material are not suitable, and are not oil-resistant or in a poor position, resulting in oil leakage at the seal.
6. The compressor is used for pressure reduction, the exhaust volume becomes larger, and the filter element separation effect is reduced, and the amount of residual oil is greatly increased.
7. When the compressor is working, the temperature is too high, the amount of oil evaporation is accelerated, and the oil mist concentration that reaches the oil separation core is large.Suitable for: Longevity, Fusheng, Fidelity, Ingersoll Rand, Atlas, Compaq, Queens, Ego, Marty, Berg, Barr, Xiangyang, Lingge style, Mitsui, Giant, Swan, Feihe, Schneider, Baoju, Caesar, Kobe Steel, Denver, Hitachi, Quincy, Tanabe, Iwata.
