------------------------------------------------------------------------
Universal RAI blowers are heavy duty blowers designed with detachable rugged steel mounting feet that permit easy in-field adaptability to either vertical or horizontal installation requirements.

------------------------------------------------------------------------

The Universal RAI DSL (URAI DSL) blower features splash oil lubrication on both the gear end AND drive end. The drive end has two shaft-mounted oil slingers and the gear end has ROOTS’ exclusive “figure-eight” gearbox design that improves oil distribution to maximize gear and bearing life. Sight glasses (3/8”) are provided for accurate oil level confirmation.

--------------------------------------------------------------------------

Because of the detachable mounting feet, these units can be easily adapted to any of four drive shaft positions - right hand, left hand, bottom or top. 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 and cast iron involute impellers. Carburized and ground alloy steel spur timing gears are secured to the steel shafts with a taper mounting and locknut. Oversized antifriction bearings are used, with a cylindrical roller bearing at the drive shaft to withstand V-belt pull.

The Universal RAI features thrust control, with splash oil lube on the gear end and grease lube on the drive end. After standard tests, the unit is sprayed with a protective paint and boxed or placed on skids.

STRONGEST WARRANTY IN THE INDUSTRY- ROOTS™ Universal RAI® blowers are warranted for two years plus an additional 6 months for shipping and construction where required.
