Oil-free screw compressors deliver air with no oil in the compression chamber, using timing gears and external cooling instead.
Two-Stage Oil-Free Design
Many oil-free machines use two stages with intercooling, since dry compression generates more heat than oil-injected designs.
Timing Gears and Seals
Precision timing gears keep the rotors synchronized without touching, while seals separate the compression and lubrication systems.
Where Oil-Free Is Required
Food, pharmaceutical, electronics and instrument air applications demand the purity that oil-free compression provides.
