The general mechanism of an air compressor is a piston or rotary component (e.g. rotary screw or vane) that draws in surroundings, which is compressed right into a storage Water Lubricated Air Compressor container. Naturally, because the piston or rotary component needs to move regularly and smoothly because of this to function, 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 maintain air compression efficiency.

Oil-free of charge air compressors also use a piston or rotary element, but they get around the lubrication problem by coating the compression element with a pre-lubricating materials like Teflon. Some oil-free compressors may also use water instead of essential oil for the lubricating and cooling process. These alternate materials safeguard the pump and invite the mechanism to go smoothly with no need for any oil-based or synthetic lubrication.
