Side channel blowers

The side channel blowers from Elektror airsystems are equally suitable for high negative and positive pressures.

Side channel blowers from Elektror airsystems

Side channel blowers, also known as vacuum pumps or vacuum compressors, can generate significantly higher pressures than industrial fans. However, a side channel blower generates lower air flow than, for example, centrifugal fans. The operating principle of vacuum pumps has its own technology: the air gets sucked in through a fast rotary vane impeller. After this, the air in the side channel blower gets pushed and compressed outwards by the centrifugal force. It flows through the side channel back into the inner part of the vacuum blower and gets compressed again between two further blades. The second compression enables the pumps to generate significantly higher differential pressures.

Side channel blowers for your application

Elektror side channel blowers can generate turbo differential pressures up to 750 mbar (75,000 Pa) and airflows up to 1,150 m³/h. Each type of Elektror vacuum blower works completely oil-free. There are different types of side channel blowers: single stage (SD, 1SD) and double stage (2SD) types as well as side channel blowers, which can only be run with a frequency converter (SD-FU/FUK). Generally, all Elektror pumps can be set and regulated with a frequency converter for energy-efficient use. Gas can also be conveyed with our side channel blowers.
