Principle
WINDRYOur Screw Vacuum Pump is a masterpiece of engineering, featuring dual paralleled screw rotors and a precisely designed pump body that create multiple sealed spaces. The meticulous design ensures no contact or friction between the rotors and pump body, enhancing durability. Driven by reverse gears, it guarantees seamless and continuous gas transfer, offering unrivaled performance from inlet to outlet.
Thanks to its frictionless design, the dual rotors and pump body eliminate the need for lubrication, ensuring the delivery of pristine, clean gas. The streamlined pathway and strategic outlet positioning below the rotors enhance drainage capabilities and simplify maintenance. Outperforming traditional claw and rotor vacuum pumps, our design offers outstanding efficiency in drainage and exhaust, coupled with remarkable ease of maintenance.
