For screw air compressor can also be divided into oil air compressor and oil free air compressor. For the industry in the pharmaceutical, medical and other high quality requirements of compressed air, oil-free requirements of these industries to choose oil-free air compressor is not questioned. However, for industries with slightly lower requirements, we need to make a comparison to see whether to choose an oil-free air compressor or a micro-oil air compressor.
In fact, oil-free air compressor is also different:
1. In the air compressor system, no lubricating oil is added, and pure water is used for lubrication, cooling, sealing, and noise reduction. There is no lubricating oil involved in the operation of the air compressor. Therefore, the compressed air has no lubricating oil.
2. In the air compressor system, lubricating oil is involved in the operation of the air compressor, but the lubricating oil is isolated from the compression zone by means of sealing isolation. The lubricating oil is only responsible for lubricating the bearing and does not participate in compression.
However, it is worth noting that even the compressed air of the oil-free air compressor in the first case is not 100 percent oil-free. Because the air contains trace amounts of oil, in some places, the oil content in the air is higher. Therefore, even if the first oil-free air compressor is used, the compressed air still needs to be processed.
The price of oil-free air compressor is much higher than that of oil-free air compressor. Therefore, if we do not require high gas, we can choose a micro-oil screw air compressor. Then carry out subsequent treatment.
However, if your equipment or use scenarios require high gas requirements, such as medical, electronics, semiconductors, etc., it is still recommended to use oil-free air compressors as much as possible. For example: Shanghai Granklin Group production of water-lubricated oil-free screw air compressor.
Of course, the most important thing is to see whether the compressed air processed by the final post-processing equipment can meet the needs of the industry.
