Dresser Roots U-RAI Positive Displacement Blowers
All Universal RAI® (URAI) series blowers are heavy duty rotary blowers in a compact, sturdy design engineered for continuous and maximum reliability. These blowers have grease lube on the drive-end with splash oil lube on the gear end. Roots’ exclusive figure-8” gearbox design improves oil distribution and lengthens bearing and gear life.
This series features a grey iron casing, carburized and ground alloy steel spur timing gears secured to steel shafts with a taper fit and locknut, and grey iron involute impellers.
Oversized anti-friction bearings are used, with a heavy duty cylindrical roller bearing at the drive shaft to withstand V-belt pull.
The standard URAI blower features universal detachable rugged steel mounting feet to permit easy in-field adaptation to either vertical or horizontal installation requirements and any of four drive shaft positions – top, bottom, right or left hand. All frame sizes are center-timed to allow for rotation in either direction.
