Claw vacuum pumps feature two claw-shaped rotors that move in opposite directions mounted in a housing. The shape of these claw rotors extracts, compresses and expels air or gas. The rotors do not come in contact with each other or the housing, so no lubricants or operating fluids are required in the compression chamber.
The minimal clearance between the rotors and the chamber housing optimizes the internal seal and ensures constantly high pumping speeds. A synchronizing gearbox maintains precise rotor timing.
