What is a Hydrovane Rotary Vane Compressor?

The Rotary Vane Compressor has been around for well over 100 years. It was invented by Charles C. Barnes, who was granted the patent on 16 June 1874.

The Hydrovane series rotary sliding vane compressors are reliable, versatile, powerful and cost effective. They can be found throughout all sectors of industry, including automotive, food and beverage, energy and manufacturing including a vast number of specialist solutions. With its low noise level the Hydrovane compressor can be installed almost anywhere.

How Does A Hydrovane Compressor Work?

• A rotary vane compressor is essentially a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity.
• The vane-type compressor consists of a cylindrical rotor with longitudinal slots in which radial sliding vanes are fitted.
• The rotor is positioned off-centre within a cylindrical housing.
• The spaces between adjacent vanes form pockets of decreasing volume from a fixed inlet port to a fixed discharge port.
• Compressor inlet and discharge valves are not employed in the design.

The single rotor design, running at standard motor speeds facilitates the use of a direct drive  arrangement, without the need for belts and pulleys. A rotary sliding vane, single stage lubricant sealed compression element is directly driven as standard by a high efficiency motor. Built-in pressure control ensures the compressor exactly matches air demand. Engineered for global markets, the compressors are rated for continuous operation in ambient temperatures up to 40° C / 104° F.
