VRa Oil Free Screw Gas Compressors

Large pressure differentials, combined with volumetric efficiency rates: that is what differentiates AERZEN VR compressors from other rotary lobe machines that also operate according to the positive displacement principle with internal compression. A special 4+6 rotary profile brings this plus efficiency to process gas applications. The highly available VR compressors can be designed as either single stage or multistage. With variable drive types such as direct drive or helical gearing. Flanged or mounted separately. And in principle designed with the conveying direction from top to bottom—an important prerequisite for fluid injection, which is often necessary in cases of highly contaminated or polymerizing gases.
