Rotary Vane Compressors

The Hydrovane series rotary sliding vane compressors are reliable, versatile, powerful and cost effective.

Constant improvements in technology and ever increasing demands for energy saving features mean things have to change. Our engineers challenged themselves to do something better. Retain the features which make Hydrovane a great product, admired by thousands of owners worldwide, but take it forward.

With over three quarters of a million sold compressors worldwide, we know we can satisfy your requirements.

The rotor, has a number of slots machined along its length into which fit sliding vanes that ride on a film of oil. The rotor rotates within a cylindrical stator. During rotation, centrifugal force extends the vanes from their slots, forming individual compression cells. Rotation decreases the cell volume, increasing the air pressure. 

The heat generated by compression is controlled by pressurised oil injection. The only continually moving part is the rotor, which is directly driven at very low speed (1450rpm), offering unrivalled reliability. The main benefit of this technology means that vane compressors last for a very long time and are an extremely reliable & proven technology.

The high pressure air is discharged through the outlet port with the remaining traces of oil removed by the final oil separator.

Compression capabilities:

CompAir's Vane compressors operate between 1.1 kW to 22 kW (1.5 to 29.5 hp), producing working pressures of 7 to 8 and 10 bar (101 to 145psi).
