  1. Becker Side Channel BlowersSV 5. / SV 7. / SV 8. Series ... difference in design and performance 06.10.2006, Rm

  2. Becker Side Channel Blowers History • Side channel blowers have been developed in the 50s simultaneously by Siemens and Becker (2. generation) • Siemens introduced the side channel blowers about 3 months earlier than Becker • There are some substantial differences in the design of Becker´s side channel blowers, which are still existing (especially the impeller design) 06.10.2006, Rm

  31. Becker Side Channel BlowersSV 5. / 7. / 8. Series - Summary • Do not sell side channel blowers by KW (usually our blowers can be selected 1 to 2 sizes smaller compared to cheap blowers made in e.g. Italy or China) • Do not select side channel blowers by free air flow but refer to operation point • Please take care if you operate with the atmospheric or with the volumetric flow rate (most of our competitors are showing the volumetric flow curve) 06.10.2006, Rm
