C-Series dry claw vacuum pumps

Elmo Rietschle C-Series dry, contact-free claw vacuum pumps. Two rotors rotate in opposite directions without contact and compress gas through internal volume contraction — significantly more efficient than traditional rotary-lobe design. C-VLR is the proven generation, with flow 60–1140 m³/h and ultimate vacuum 100–200 mbar abs. The newer C-VLU reaches 30–50 mbar abs — previously only achievable with oil-lubricated pumps — with up to 50% smaller footprint and better specific performance.
