Becker SV 300/2 – two-stage side channel blower for vacuum and pressure
The SV 300/2 delivers 160 m³/h at 50 Hz and 190 m³/h at 60 Hz. Becker supplies it with various motors (2.2 kW, 3.0 kW at 50 Hz); depending on the motor and mains frequency it reaches down to −410 mbar relative in suction operation and up to +515 mbar relative in pressure operation. Width × height 370 × 426 mm, suction and pressure connection G 2 1/2". The values for each motor are given in the technical data.
Contact-free compression
In a side channel blower an impeller rotates in the housing without contact. The blower works without oil, with little wear and little maintenance. The two-stage design reaches higher pressure differences than the single-stage design at a lower volume flow.
