Rotary Vane Air Compressor

A rotary vane air compressor consists of a cylindrical housing vessel containing a set of adjustable rotating vanes and exchanging air through an inlet and outlet. The vanes are set on an eccentric drive shaft which faces the outlet. As the drive shaft rotates, the length of the adjustable vane closest to the outlet shortens, compressing the air within the spinning chamber. This air then escapes through the outlet and can be powered for subsequent further processing. Rotary vane air compressors are ideally suited to small and quiet applications such as the automotive and agricultural industries. They are less suitable for applications requiring oil-free or otherwise uncontaminated air, or for use in potentially contaminated environments such as wood shops.

Advantages of rotary vane compressors

Low-speed reliability

Flexible compressor configurations to suit different process requirements

Quiet operation with noise levels as low as 65 dBA

Easy to service due to minimal consumable parts and easy access to air filters. There is also a large oil capacity and large filter size for longer service intervals. 

These compressed air units are backed by an industry-leading warranty. 

Cost Savings and Energy Efficiency

Principle of operation

Rotary vane compressors utilize a recirculating rotor with slots that contain blades that can slide in and out. The rotor is located slightly off-center within the system, which means that as it rotates, the blades move under centrifugal force until they contact the compression chamber. As air enters the chamber it is captured by the blades, meaning that the volume of air captured in the chamber gradually decreases as the rotor continues to rotate under centrifugal force. It is this reduction in volume that increases the pressure of the now compressed air.
