Q: What is the difference between an oil compressor and an oil free compressor?
Answer: Oil compressors are lubricated with twin-screw lubricating oil, and the compressed gas is oily. It is not suitable for industries such as pharmaceuticals, food, chemical, and semiconductors that have high gas requirements.
Oil free compressors have a “water lubricated air compressor”, which uses water to lubricate the head of the air compressor. The compressed air produced does not contain oil, covering scenarios where oil based compressors cannot be used.
Shanghai Granklin Group Co., Ltd. specializes in the production of “water lubricated air compressors”. Our screw air compressors are universal mechanical equipment without oil, providing enterprises with a continuous supply of clean and oil-free compressed air.
