 Centrifugal Blower Working Principle

Republic Centrifugal Blower Working Principle

Centrifugal blowers provide a steady volume of air to supply energy-efficient pressure or vacuum.

Air enters at the center of a spinning impeller, and is divided between the impeller’s vanes. As the impeller turns, it accelerates the air outwards using centrifugal force. This high-velocity air is then diffused and slowed down in the surrounding blower housing to create pressure.  The pressure or vacuum offers a wide range of volumetric flows possible due to the geometry of the open impeller.





Advantages of Centrifugal Air

Centrifugal air is energy-efficient and inexpensive, especially when compared to compressed air as an alternative. Centrifugal blowers use much less horsepower to create flow, thus using less energy than compressed air. When replacing compressed air, centrifugal blowers can offer a payback of months or even weeks.

Republic Centrifugal Blowers are engineered to be robust and efficient, while easy to maintain. Drawing on over 50 years of blower and manufacturing experience, Republic's RB Series provides a highly effective stream of air for your air or gas handling requirements. The field-proven design generates a high velocity stream of air while the permanently grease-packed ceramic-hybrid ball bearings require no maintenance. Engineered, manufactured, and assemebled in Dallas, TX, USA Republic uses only the highest quality materials. The small footprint works well for low profile applications, as well.
