Series C spun aluminum exhaust fans are specifically designed for roof mounted (CUE/CUBE) applications. Contaminated or grease laden exhaust air can be discharged directly upward, away from the roof surface. The fans feature a one piece windband continuously welded to curb cap and double studded isolators for true vibration isolation. Capacities range from 70 to 30,000 cfm and up to 5.0 in. wg.
