Becker VARIAIR SV 500/1 – variable-speed side channel blower
The VARIAIR SV 500/1 delivers up to 1000 m³/h. In suction operation it reaches down to −370 mbar relative, in pressure operation up to +530 mbar relative. The VARIAIR frequency converter (400–480 V ±10 %, 50/60 Hz, max. 35 A) controls the frequency between 10–100 Hz. Weight with motor and converter 97.5 kg, dimensions 599 × 474 × 625 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.Further versions
- Gas-tight: gas-tight compressor version for inert gases, leak rate < 1 × 10⁻⁵ mbar·l/s (helium leak test, whole unit); with 7.5 kW motor and VAU-C converter (up to 11.0 kW) 910 m³/h, max. pressure ratio 1.295 p/p, 78.5 kg; with 11.0 kW motor and VAU-D converter (up to 30.0 kW) 930 m³/h, max. pressure ratio 1.315 p/p, 90.8 kg; 10–100 Hz, 71 dB(A) at 1.135 p/p (67 Hz); connections DN 100 ISO-K (DIN 28404), optionally DN 100 (DIN 32676-A); values measured for argon
