Principle
WINDRYOur Screw Vacuum Pump is an engineering marvel, expertly crafted with dual paralleled screw rotors within a precisely designed pump body. This design creates multiple sealed chambers where the rotors and body maintain exact clearances, ensuring no contact or friction. Driven by precision reverse gears, gas moves seamlessly from the inlet to the outlet, delivering unmatched performance.
With an innovative frictionless design, our dual rotors and pump body require no lubrication, ensuring the delivery of immaculate gas. The efficient gas transfer, coupled with an optimized pathway, ensures peak performance. The strategically positioned outlet below the screw rotors enhances drainage and simplifies cleaning, surpassing claw and rotor vacuum pumps in both efficiency and effortless maintenance.
