UBVL Belt Drive Upblast Roof Ventilators

Description

UBVL belt drive upblast roof ventilators provide superior performance in a low silhouette design, with capacities to 44,000 cfm. These rugged industrial roof ventilators are constructed with a heavy duty welded steel base, a galvanized butterfly exhaust damper section, and a spark resistant cast aluminum airfoil axial impeller. The UBVL ventilators have a v-belt drive for quiet, low speed operation. They are ideal for general ventilation applications as well as for removal of process related fumes, dust and smoke.
