Q: What is the difference between an oil compressor and an oil-free compressor?

Answer: The oil compressor is lubricated by twin-screw lubricating oil. The compressed gas is oily, which is not applicable in industries with high gas requirements such as pharmaceuticals, food, chemicals, and semiconductors.

Oil-free compressors have "water-lubricated air compressors", that is, water is used to lubricate the air compressor head. The compressed air produced does not contain oil, covering scenes where oil compressors cannot be used.
