HR Blowers supply Howden RAM rotary blowers which are heavy duty units designed with integral-shaft ductile iron impellers having an involute profile. This product line is designed with detachable rugged steel mounting feet which offers custom installation for either vertical or horizontal installation. Additionally, certain lines we supply incorporate ROOTS WHISPAIR technology that reduces both noise and power loss.
