Vane Compressors

The operation of a vane compressor is similar to that of many compressed air expansion motors. The vanes are typically made of special cast alloys, and the majority of vane air compressors are oil-lubricated. A stator housing eccentrically mounts a rotor with radial, movable blade-shaped vanes. When it rotates, centrifugal force presses the vanes against the stator walls. When the distance between the rotor and stator grows, air is drawn in.

It is oil-free, high-pressure discharge of fluids that can clog cargo pumps. These compressors, built from corrosion-resistant, hard-coated cast iron to withstand harsh environments and operating conditions, have been designed to address containment concerns, purity standards, and residual product evacuation.
