RootsTM Rotary Lobe Blowers

Products | Blowers | Roots lobe blowers

​Since 1854, we have been continuously manufacturing and developing the rotary positive displacement blowers under the industry respected name RootsTM.

​Today, we produce robust, heavyduty bi-lobe or tri-lobe designs that deliver reliable performance with innovative Whispair™ technology for low noise, low pulsation compression.

Roots has its main manufacturing facilities including the original Roots factory in Connersville, IN (USA). The factory produces more than 25,000 machines yearly. You can read about the history of the Roots business on our latest blog 'Evolution of Roots brand in the UK', from the old WC Holmes Huddersfield factory through acquisitions by Peabody Holmes, Dresser Roots and GE before finally the purchase of the business by Howden.
