Universal RAI-G ® Positive Displacement Blowers - Dresser ROOTS

Universal RAI-G ®


Universal RAI-G gas blowers are heavy duty rotary blowers designed with mechanical seals and rugged steel mounting feet. Optional feet are available for horizontal installations. The compact, sturdy design is engineered for continuous service when operated in accordance with speed and pressure ratings. The basic model consists of a cast iron casing, carburized and ground alloy steel spur timing gears secured to steel shafts with a taper mounting and locknut, and cast iron involute impellers. Oversized anti-friction bearings are used, with a cylindrical roller bearing at the drive shaft to withstand V-belt pull. The Universal RAI-G® features splash oil lube on the gear end and grease lube on the drive end. ROOT's exclusive "figure-eight" gearbox design improves oil distribution to maximize gear and bearing life. Each unity is mechanically tested and given a 15 psig static leak test. A 1/8" NPT purge port is provided at each seal for buffer gas application as required. After testing, the unit is sprayed with a protective paint, and boxed or skid mounted for delivery. Accessories are available through our distributors. ROOTSTM Synthetic Oil and grease is recommended to maintain warranty.
