Becker VARIAIR SV 300/2 – variable-speed side channel blower
The VARIAIR SV 300/2 delivers up to 300 m³/h. In suction operation it reaches down to −410 mbar relative, in pressure operation up to +570 mbar relative. The VARIAIR frequency converter (VAU7.5/3, 7.5 kW, 400–480 V ±10 %, 50/60 Hz, max. 20 A) controls the frequency between 10–100 Hz. Weight with motor and converter 49.5 kg, dimensions 512 × 370 × 499 mm (L × W × H), suction and pressure connection G 2 1/2".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); 280 m³/h, max. pressure ratio 1.49 p/p, 10–100 Hz, 78 dB(A) at 1.35 p/p (67 Hz), 65 kg; connections KF 50 (DIN 28403, ISO 2861); values measured for argon
