Howden Roots refined the standard URAI line using computer-aided design techniques to incorporate the Roots exclusive WHISPAIR jet. The WHISPAIR jet uses shock suppression techniques for noise and pulsation reduction. This exclusive WHISPAIR feature can reduce noise 3-5 dB on typical installations. Like the standard URAI Blower, the URAI-J features universal detachable steel mounting feet to permit easy in-field adaptation to any of four positions and grease lubrication on the drive end.
