UBV Belt Drive Upblast Roof Ventilators
Description
UBV belt drive upblast roof ventilators are constructed with a heavy duty welded steel base, galvanized damper section, and a cast aluminum airfoil axial impeller. As a result, these rugged, high quality industrial roof ventilators provide superior performance. This aerodynamically efficient fan is available in diameters from 18″ through 60″, with capacities ranging to 61,000 cfm. Because the UBV roof ventilator has its motor located outside the air stream, it is ideal for hot or contaminated air streams. UBV upblast roof ventilators work in a variety of applications such as general ventilation, moisture-laden air, and mild contaminants in the air stream.
