Can oil-free air compressor add some lubricating oil?

Lubricating oil is usually not needed and should not be added to oil-free air compressors. The original intention of the oil-free air compressor is not to use lubricating oil during the compression process to avoid mixing oil into the compressed air, thereby ensuring the purity of the output air. The addition of lubricating oil may damage the internal components of the oil-free air compressor, affect its performance and service life, and pollute the output compressed air.

Oil-free air compressor is usually lubricated with water during operation to complete the functions of smoothness, cooling, sealing and noise reduction. The compressed air provided has no oil pollution, and the discharged water does not need special treatment, which meets the requirements of environmental protection.
