Small oil-free air compressor by what lubrication

Small oil-free air compressors mainly rely on non-oil lubricants or special lubrication methods for lubrication. Specifically, there are the following common lubrication methods:

internal lubrication: Some oil-free air compressors are lubricated by internal lubrication. In this way, the heat storage material is mainly heated by the heat generated during the air compression process and stored inside the machine. In the subsequent compression process, these thermal storage materials will release the previously stored heat, provide lubrication for the compressed air and reduce the operating temperature.

External lubrication: External lubrication mainly uses special lubricants or materials to provide lubrication and cooling of the machine. These lubricants can be liquid, dry or coated, etc., which are applied to critical parts of the compressor to reduce friction and wear.

Water lubrication: For water-lubricated air compressors, water is the main lubricating medium. Water not only cools, but also lubricates key parts of the machine during compression, thereby reducing wear. This method is used in some specific oil-free air compressors, such as water-lubricated air compressors produced by Shanghai Granklin Group.

As for the Shanghai Granklin Group, they have successfully developed many types of compressors, including oil-free water lubrication screw air compressors. These products adopt advanced water lubrication technology, which not only improves the efficiency of the compressor, but also ensures the purity of the compressed air.

In general, there are many ways to lubricate small oil-free air compressors, which depends on the design and application requirements of the compressor.
