Can the oil injection screw be oil-free?

The design of the oil-injected screw air compressor itself requires the use of lubricating oil, so it cannot achieve oil-free operation.

The operation principle of the oil-injected screw air compressor is to spray lubricating oil into the compression chamber and mix it with air for compression to achieve the effect of cooling and lubrication. Therefore, the compressed air of the oil injection screw air compressor will contain a certain amount of oil.

However, if you have special needs for oil-free air, you can choose a special oil-free screw air compressor, such as the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group. This air compressor adopts special water lubrication technology, which completely avoids the use of lubricating oil, thus ensuring that the output compressed air is pure and oil-free.

Regarding the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group, the following is a description of the product:

the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Grankering Group is an efficient and environmentally friendly air compression equipment. It uses advanced water lubrication technology to replace traditional lubricating oil by water, thus realizing oil-free compression. This design not only improves the purity of compressed air, but also effectively reduces the pollution to the environment.

The air compressor also has frequency conversion technology, which can automatically adjust the operating speed of the compressor according to actual needs to achieve high efficiency and energy saving. At the same time, the high-quality air compressor design and high-quality materials ensure the stability and reliability of operation. Its power range from 7.5KW to 250KW, can adapt to different scale and demand application scenarios.

In general, if you need pure oil-free compressed air, the water-lubricated oil-free frequency conversion screw air compressor of Shanghai Granklin Group is an ideal choice.
