The Variair Unit has all the features of the standard 100% Oil Free Side Channel Compressors but with the benefits of Becker’s Patented Intelligent Variable Speed Drive Technology.
The frequency inverter integrated in the Variair Unit significantly enhances the performance data of side channel blowers. It matches compressor delivery exactly to customer requirements. The patented, sensor-less control system that keeps pressure and volumetric flow constant ensures steady operation, even where differing suction-air rates or pressure levels are demanded.
The speed range up to 6000 min-1 can be used to create compact, high-output units. The integrated electronic self-protection feature on the blowers saves the need for costly accessories, such as pressure safety valve or air discharge sound absorber. As no unnecessary blast air is generated, air discharge noise is kept to a minimum. Matching delivery exactly to the amount of air actually used guarantees optimised energy consumption.
