Vane compressors and vacuum pumps

Vane compressors and vacuum pumps offer oil-free operation, long service life and low operating costs, making them ideal for a wide range of environmental and industrial applications. 

Pumping action is produced by a series of sliding, flat vanes as they rotate in a cylindrical housing. As the diagram shows, an eccentrically mounted rotor turns and the individual vanes slide in and out of their slots by centrifugal and pressure-loading forces. This creates a series of aircompartments of unequal volume against the wall of the housing. These compartments get larger during the suction part of the cycle, creating vacuum at the intake port and smaller during the discharge portion of the cycle, creating pressure at the exhaust port.

Applications:

• Aeration (wastewater treatment, aquarium)
• Medical equipment
• Packaging
• Graphic industry
• Sampling
• Food industry
• Laboratory
• Vacuum thermoforming
• Vacuum tables
