    The RBUMO is an upblast axial exhaust fan designed to discharge air and contaminants up and away from the roof surface for most commercial and many industrial applications. This belt-driven fan features a welded steel propeller designed to run at lower RPMs, generating low sound levels, making the RBUMO the ideal solution for sound critical installations. The motor is located outside of the airstream to allow for high temperature air to be exhausted as well as roof access to the motor.

    • Variable pitch adjustable motor pulley to optimize fan performance
    • Adjustable motor plate for belt tensioning
    • Drive assembly belts, pulleys and keys are sized for 150% of driven horsepower
    • Belts are static–resistant and oil free
    • Cast iron pillow block bearings with grease fittings
    • Steel butterfly dampers prevent backdrafts and provide weather protection when fan is not in operation
    • Drive frames are die-formed, galvanized structural settl to provide a rigid platform for motors, shafts, bearings and drives
    • Windband mounting brackets are designed to also be used as lifting lugs for ease when lifting unit to the roof deck
