Roots Universal RAI (URAI)Intended to permit easy installation into any system, the Roots Universal-RAI (URAI) series delivers performance and convenience. The URAI series combines detachable feet, to allow horizontal or vertical installation, and dynamically balanced impellers, center-timed to permit rotation in either direction.
The standard URAI blower offers vacuums to 16″ Hg (542 mbar), pressures to
15 psi (1034 mbar), with flows from 2 to 2370 cfm (3.4 to 4026 m3/hr).
