Universal RAI-J DSL Blower

Frame Sizes 33J thru 56J

ROOTS Patented Universal RAI-J Whispair Dual Splash Lubricated (DSL) blowers are heavy duty rotary units in a compact, sturdy design, engineered for continuous service when operated within speed and vacuum/pressure ratings. The basic model features a cast iron casing with a computer-designed cast relief for noise and shock suppression. Carburized and ground alloy steel spur timing gears are secured to steel shafts with a taper mounting and locknut. The unit features cast iron involute impellers. Oversized anti-friction bearings are used with a cylindrical roller bearing at the drive shaft to withstand V-belt pull. Detachable rugged steel mounting feet permit easy in-field adaptability to either vertical or horizontal installation requirements.

The Universal RAI-J DSL design incorporates dual splash lubrication to the gear AND drive ends. Roots' exclusive "figure eight" gearbox design improves oil distribution to maximize bearing and gear life. Sight glasses (3/8") are provided for accurate oil level confirmation.
