Q: Is there any difference between an oil-free air compressor and an ordinary air compressor?

Answer: There is a difference.

The oil content of the gas compressed by the oil-free air compressor is oil-free. For example, the water-lubricated oil-free air compressor produced by Shanghai Granklin Group uses water as a lubricant at the head of the air compressor, and there is no lubricant involved in the work.

Ordinary air compressor because the air compressor head needs lubricating oil, so the compressed gas oil content is relatively high. Can not be used in medicine, chemical, food and other fields.
