Side channel blowers are used to generate suction or blow air in heavy industrial applications. These turbo dynamic blowers are wear and maintenance free.

Side channel blowers contain a non-contact, fast rotating impeller inside a blower housing. On both sides of the impeller, there are two annular separate side channels together with the housing. The rotating impeller draws air in through the inlet side, accelerates the air or gas inside the housing and then discharges it through the outlet side when fully pressurized.

With single-stage blowers, the air rotates once inside the housing via both impeller sides before being blown out. This parallel operation results in a higher volume flow.

With two-stage blowers, by means of an internal deflection of the air from the first to the second impeller side, the air rotates twice inside the housing before being blown out. This double operation results in a higher vacuum or pressure.
