Q: Is there a difference between oil-free air compressors and regular air compressors?
Answer: There are differences.
The oil content of the compressed gas from an oil-free air compressor is non oil. For example, the water lubricated oil-free air compressor produced by Shanghai Granklin Group uses water as the lubricant at the head of the air compressor, without the involvement of lubricating oil during operation.
Ordinary air compressors require lubricating oil at the head of the compressor, so the oil content of the compressed gas is relatively high. It cannot be applied in fields such as medicine, chemicals, and food.
