Principle
WINDRYOur Screw Vacuum Pump is a masterpiece of engineering, featuring dual paralleled screw rotors paired with a precisely crafted pump body. This innovative design forms multiple sealed spaces, with the rotors and pump body maintaining ultra-fine clearances to avoid contact and friction. The use of reverse gears ensures a seamless, continuous transfer of gas from the inlet to the outlet, delivering an unparalleled performance.
Boasting a frictionless design, our dual rotors and pump body do away with the need for lubrication, thereby ensuring a supply of clean gas. The continuous gas transfer, along with a streamlined pathway, results in superior efficiency. A strategically positioned outlet below the screw rotors enhances drainage and simplifies cleaning. Our design, free from intermediate bulkheads, outperforms claw and rotor vacuum pumps in both drainage and exhaust efficiency and is astonishingly easy to maintain.
