Does the air compressor have to be oil-free?

Air compressors do not have to be oil-free, but choose whether to use oil-free air compressors according to specific application requirements. Traditional air compressors usually use lubricating oil to lubricate and cool the moving parts during compression. These lubricating oils may leave trace amounts of oil in the compressed air. However, in some occasions with high air quality requirements, such as food, medicine, electronics and other industries, oil-free air compressors are required to provide pure compressed air.

The water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group is a special air compressor, which uses water lubrication technology to replace traditional lubricating oil. This design completely eliminates the risk of contamination from lubricants and provides truly oil-free compressed air. Water lubrication technology is not only environmentally friendly, but also can effectively reduce the operating temperature and improve the efficiency of the air compressor.

In addition, the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group is also equipped with frequency conversion technology, which enables the air compressor to automatically adjust the operating speed according to actual needs. This not only saves energy, but also reduces equipment wear and maintenance costs. Its power range from 7.5KW to 250KW, suitable for all sizes of oil-free compressed air needs.

In summary, whether to choose an oil-free air compressor depends on the specific application requirements. Where pure compressed air is required, the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Grankering Group is a reliable choice.
