Upblast power roof ventilators are designed for long life, low maintenance and all-weather performance. The proven upblast design is the most cost effective roof exhauster built today and offers the best value of all PRV types. These units are designed for general ventilation, efficiency and economical. Suggested for use in commercial and industrial applications including factories, warehouses, commercial buildings, machine rooms or any areas
requiring the movement of air, where it is necessary for the fan
assembly to be located above the roof. Belt drive PRVs are suggested where the motor, belts and bearings must be isolated from the airstream. The units provides an economical solution for most of these applications, while some models are suggested where a heavier duty unit or greater performance capabilities are required.
