Principle
WINDRYOur Screw Vacuum Pump is a marvel of engineering excellence, featuring dual paralleled screw rotors within a precision-crafted pump body, forming multiple sealed spaces. The innovative design ensures that the rotors and pump body maintain precise clearances, preventing any contact or friction. Driven by expertly synchronized reverse gears, the gas is efficiently and continuously transported from the inlet to the outlet, guaranteeing unmatched performance.
This frictionless design eliminates the need for lubrication, delivering pristine, clean gas with each use. The seamless gas transfer, coupled with an optimized pathway, ensures peak performance efficiency. With a strategically placed outlet below the screw rotors, drainage is enhanced, and cleaning is simplified. Our design, with no intermediate bulkhead, stands superior in drainage and exhaust efficiency compared to claw and rotor vacuum pumps, offering ease of maintenance as an added benefit.
