Misunderstandings of oil-free air compressors

1. The compressed air produced by the oil-free air compressor is oil-free. Although no oil is used in the compression chamber, the oil will not come into contact with the compressed air, but the oil vapor in the atmosphere cannot be removed by itself, and the compressed air still contains a small amount of oil impurities. When measured, the oil content in the compressed air produced by an oil-free air compressor depends on the area and air quality. The environment of the air compressor room, the environment of the air compressor room, and the environment of the air compressor room are closely related to the cleanliness of the compressor.

 

2. Oil-free air compressors do not use oil. Although the oil does not come into contact with the air during the process of compressing the air, it will still be used to cool the compressor and lubricate the running parts to ensure the normal and stable operation of the compressor.

3. The compressed air produced by the oil-free air compressor is free from pollution. There are many pollutants in the atmosphere, including dust, water vapor, oil vapor, microorganisms, etc. The compressed air produced by the oil-free air compressor can only ensure that the compressed air in the compression project is free of oil, but it cannot remove the impurities of the air itself. This means that the compressed air produced by the oil-free compressor is free of pollution, and the use of air treatment products can help reduce pollution to the required level.

 

4. Oil-free air compressors do not require air treatment products. As mentioned in point 3, the gas quality of the compressed air produced by oil-free air compressors is largely controlled by the environment, so users need to adjust according to their own requirements for compressed air quality. It is necessary to configure corresponding post-processing equipment to meet its own needs for compressed air quality.

5. Low cost of oil-free screw air compressor In fact, since the compression ratio is much smaller than that of oil-lubricated compressors, the energy consumption is higher. The oil-free compressor with the same power can reduce the gas production by more than 40% compared with the energy-saving screw compressor. Although there is no oil lubrication in the compression chamber, the grease and air filter in other parts still need regular maintenance. The iron core rotor is generally treated with coating, which has a long service life. It has high requirements on water and is easily damaged. Main engine maintenance is an inevitable choice for oil-free engines, and the cost is high, accounting for about 50% of the equipment cost.
