In aeration applications where the pressure required is greater than that available from a regenerative blower, consider Roots® Rotary Lobe Blowers. They consume less energy at elevated pressures than comparative regenerative blowers. Roots® Universal RAI® blowers are heavy-duty and made in the USA.
Completely assembled packages are possible using one of the 17 frame sizes of Universal RAI® blowers. Packages may be customized for your application. Flowrates up to 2,370 cfm and pressures to 15 psi are available.
To give example pricing, we've packaged standard systems (like RB32A shown), with electric motors, inlet filters, silencers, steel bases, motor adjusting rails, V-belt drives and belt guards (pressure relief valves, as shown, are not included). If one of the standard packages does not fit your needs, let us know your exact requirements and we will provide a price quote. Roots® 18-month uncontested warranty guarantees the repair or replacement of any unit that malfunctions for any reason.
Roots® Universal RAI® blowers feature machined cast-iron casings, head plates and impellers. The impellers are dynamically balanced and antifriction. Oversized bearings are used throughout. Timing gears are center-timed to allow clockwise and counterclockwise rotation and made from hardened alloy steel.
Bhp is brake horsepower. The electric motor horsepower required will be about 30% higher than the bhp to allow for belts and pulleys, 40% higher for gas engines.
Note: Due to the customized design of blower packages, please allow up to 2 weeks for production.
