Does an oil-free air compressor have oil?

When the oil-free air compressor is designed and manufactured, no lubricating oil is used in the compression chamber, so theoretically, the oil will not directly contact the compressed air during the compression process. However, this does not mean that the compressed air produced by the oil-free air compressor is completely oil-free. In fact, due to the possible presence of trace amounts of oil vapor and other impurities in the atmosphere, as well as the internal parts of the air compressor in the processing, assembly process may be residual oil, these factors may lead to compressed air containing trace amounts of oil impurities.

However, it is worth noting that the oil-free air compressor can minimize the oil content in the compressed air by using special materials and lubrication methods (such as resin material lubrication, water lubrication, etc.). For most industries with high air quality requirements, oil-free air compressors have been able to meet their needs.

Shanghai Granklin Group's water lubricated air compressor is completely free of oil?

the water-lubricated air compressor produced by Shanghai Granklin Group is a special type of oil-free air compressor, which uses water as a lubricant to replace the traditional oil lubrication method. This air compressor in the compression process, due to the use of water for lubrication and cooling, so no oil, compressed air more pure.
