VAKUUM BOHEMIA offers exclusive sale of industrial RT blowers and blowers by Elmo Rietschle, Becker, and Busch. RT blowers are a part of numerous industrial equipment, from vaporisers in coal power plants, to robotic car engine production lines, or luxurious Jacuzzis in amusement parks.

RT blowers are suitable for permanent operation and non-continuous operation, and a modified version is also available for very frequent stop-start sequences. Most models are available in stock and can be borrowed for a test run. They are usually available for shipping one day after ordering. One-phase as well as three-phase blowers are available.

Operating principle of side channel blowers

Rotations of the impeller create negative pressure at the point of suction. Air is drawn in and flows around the impeller towards the exhaust. Blowers have an integrated damper at the intake and exhaust. The impeller is turned by a TEFC electromotor with built-in fan.

Single-stage blowers


Single-stage blowers


Double-stage blowers

Single-stage side channel blowers have a 1x230V motor and are a reliable source of overpressure or negative pressure whenever a three-phase connection is not available.   Single-stage side channel blowers are a reliable source of overpressure or negative pressure with high flow.   Double-stage side channel blowers are a reliable source of overpressure or negative pressure with high flow and a higher pressure difference.
