Innovative Design and Quiet Operation

All Universal RAI (URAI) series Blowers are heavy duty rotary Blowers in a compact, sturdy design engineered for continuous duty and maximum reliability. These Blowers have a time tested lubrication system. Roots exclusive “–figure-8”” gearbox design improves oil distribution to the timing gears and lengthens bearing life. This URAI Blower combines the WHISPAIR design with the dual splash lubrication feature to offer the longest life and quietest performance of the URAI series.

The Roots Whispair URAI-J-DSL models stand out with their advanced noise reduction technology:

  • Whispair™ Feature: Reduces noise levels by approximately 3 to 5 dBA compared to conventional units under similar operating conditions, thanks to a computer-designed cast relief for noise and shock suppression.
