The patented sensor-free control system for maintaining the volumetric flow rate and vacuum pressure allows continuous operation, even when the volumes of air to be sucked vary or the pressure ratios change. Thanks to the speed range of up to 6000 min-1, compact devices can be manufactured for wide power ranges. The electronic self-protection integrated in the vacuum pumps saves expensive accessories such as vacuum safety valves or suction silencers. Noises are avoided because no unnecessary intake air is generated. Precise adaptation to the actual air requirement guarantees optimum energy consumption levels.

The innovative Becker VASF series of side channel fans in sizes 50, 80 and 120 largely fulfils the requirements for autonomous vacuum or overpressure generation systems in terms of integration capacity and efficient operation, as is characteristic of technologies that set the standards for the future. Their compact format, optimised aerodynamics, wide speed range with minimum noise and “intelligent” drive electronics give them high performance and high power concentration with low weight and small size. A modular system of standard blocks allows connection to the circuit in single-stage or multi-stage variants, with AC or DC motor. The technological advance is also expressed in a clear and slim design.
