The overall mechanism of an air compressor is a piston or rotary element (e.g. rotary screw or vane) that allures air, which is compressed right into a storage container. Naturally, since the piston or rotary element needs to move consistently and smoothly because of this to work, it generally needs to be lubricated.
In a lubricated air compressor, there is lubricating oil which will keep the piston or rotary element running well without damaging the system. The lubricant also really helps to dissipate high temperature and keep maintaining air Water Lubricated Air Compressor compression efficiency.
Oil-free air compressors also use a piston or rotary element, however they bypass the lubrication problem by coating the compression component with a pre-lubricating materials like Teflon. Some oil-free compressors could also use water in place of essential oil for the lubricating and cooling process. These alternate materials guard the pump and invite the mechanism to go smoothly with no need for any oil-based or synthetic lubrication.
