Atlas Copco Oil Free Air Compressor

Oil-free air compressors either have no mechanical contact inside the compression chamber or use alternate materials to protect the mechanism without lubrication. Most oil-free compressors utilize other materials like water or a Teflon coating to keep the mechanism running smoothly.An “oil-free” air compressor does not use any lubrication in the compression chamber. Instead, these compressors use alternate materials that protect the pump, such as water or a Teflon coating, and allow the mechanism to move smoothly without the need for any oil-based or synthetic lubrication.
