Principle
WINDRYOur Screw Vacuum Pump is expertly engineered with two parallel screw rotors and a specially designed pump body, creating multiple sealed chambers. The precision in rotor and pump body design ensures minimal clearances, preventing contact and friction. Powered by reverse gears, gas flows seamlessly from inlet to outlet, achieving peak performance.
Thanks to its frictionless construction, the dual rotors and pump body operate without lubrication, providing clean gas delivery. Continuous gas flow and a streamlined pathway enhance efficiency. The outlet's strategic positioning below the screw rotors improves drainage and simplifies maintenance. With no intermediate bulkhead, it outperforms claw and rotor vacuum pumps in drainage and exhaust efficiency, while being incredibly easy to maintain.
