Becker VARIAIR SV 400/1 – variable-speed side channel blower
The VARIAIR SV 400/1 delivers up to 800 m³/h. In suction operation it reaches down to −340 mbar relative, in pressure operation up to +430 mbar relative. The VARIAIR frequency converter (VAU11-22/3, 400–480 V ±10 %, 50/60 Hz, max. 25 A) controls the frequency between 10–100 Hz. Weight with motor and converter 75 kg, dimensions 572 × 390 × 592 mm (L × W × H), suction and pressure connection G 3".Speed control
Via the frequency the converter matches volume flow and pressure to the actual demand, instead of throttling the air volume with valves.Contact-free compression
The impeller rotates in the housing without contact; the blower works oil-free, with little wear and little maintenance.Advice and service
