... difference in design and performance06.10.2006, Rm

Page 2: Becker Side Channel Blowers SV 5. / SV 7. / SV 8.  Series

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)

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 butrefer 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)
