How to lubricate an oil-free air compressor

Oil-free air compressors usually use special lubrication methods to ensure the normal operation of the compressor without the use of lubricating oil. In oil-free air compressors, a common form of lubrication is water lubrication.

Shanghai Granklin Group Air Compressor Product Description

shanghai Granklin Group provides various types of air compressors, including water-lubricated air compressors, oil-free air compressors, frequency conversion air compressors, screw air compressors and low-pressure air compressors. These air compressors have a power range of 7.5-250KW and can operate in a working pressure range of low pressure 0.3MPa to medium pressure 4MPa. In order to maintain the performance and reliability of the air compressor, regular maintenance of consumables such as water filter elements and air filter elements are necessary.

Oil-free air compressor uses water lubrication to answer questions

question: How to lubricate the oil-free air compressor?

Answer: Oil-free air compressors usually use water lubrication systems. In such systems, water is used as a lubricant to cool and seal the moving parts of the compressor. The water lubrication system introduces water into the compression chamber of the compressor through a specially designed water supply system and sealing structure, so that a layer of water film is formed during the compression process, which plays the role of lubrication and cooling.

The main advantages of water-lubricated air compressors include:

oil-free pollution: Because no lubricating oil is used, the compressed air will not be mixed with oil, which is suitable for occasions with high air quality requirements.

Environmental protection and energy saving: water as a lubricant has good thermal conductivity, which can effectively cool the compressor and improve energy efficiency.

Easy maintenance: The water lubrication system is relatively simple, reducing the trouble of lubricating oil replacement and handling.

It should be noted that the water lubricated air compressor needs to check and replace the water filter element regularly during operation to ensure the clean and normal operation of the water supply system. In addition, due to the special structure and working principle of the water-lubricated air compressor, its maintenance and maintenance may also be different from the traditional oil-lubricated air compressor. Therefore, it is recommended that users follow the operation and maintenance manual provided by the manufacturer for operation and maintenance.
