Description
The oil-free screw compressor element
No oil means that there is no oil for sealing the rotors and for cooling the compressed air, elements and rotors. … The element is cooled by cooling water that flows through special pockets in the element casing.
In a lubricated screw compressor, the lubricant comes in direct in contact with the compressor inlet air and compressed air. … The oil contains anti-oxidants to try to reduce the breakdown of the lubrication properties due to internal conditions.
