Heavy-duty, versatile, bi lobe rotary blowers with reduced noise.
The ROOTS® Universal RAI™-J DSL (Dual Splash Lubricated) heavy-duty, versatile, rotary blowers are designed with detachable, rugged steel mounting feet that permit easy in-field adaptability to vertical or horizontal installation requirements. - Units can be easily adapted to any of four drive shaft positions: right, left, bottom, or top. Model features dual splash lube for cooler operations and greater reliability as well as WHISPAIR™ technology to reduce noise and pressure pulsations emitted from the blower.
- Pressures to 15 psig (1034 mbar)
- Vacuums to 16” Hg (539 mbar)
- Flows to 630 cfm (1070 m3/hr)
- Available with metric drive shaft and pipe connections
The URAI-J DSL combines dual splash lubrication with reduced noise and pressure pulsations for reliable operation in demanding industrial applications.
- Versatile Mounting Options: Detachable mounting feet offer versatility for four drive shaft positions: right, left, bottom, or top.
- Durable Construction: Compact and sturdy design ensures continuous service when operated within speed and pressure ratings.
- Robust Components: Basic model features durable construction with cast iron casing, alloy steel gears, and cast iron impellers.
- Enhanced Bearing Strength: Oversized antifriction bearings and cylindrical roller bearing to withstand V-belt pull.
- Efficient Lubrication System: The URAI DSL blower utilizes splash oil lubrication on both gear and drive ends, enhancing gear and bearing life.
- Improved Lubrication System: ROOTS® exclusive “figure-eight” gearbox design enhances oil distribution for extended gear and bearing life.
- Reduced Vibration: Smoother operation due to reduced pressure pulsations.
- Noise Reduction: WHISPAIR technology controls backflow of air, reducing noise levels.
- Lower Air Pulsation: WHISPAIR blowers operate with up to 40% less pressure pulsation than conventional blowers, enhancing efficiency and performance.
