These rugged industrial roof ventilators are constructed with a heavy duty welded steel base, galvanized butterfly exhaust damper section and a spark resistant cast aluminum airfoil axial impeller. The UBVL belt drive upblast roof ventilators have a v-belt drive for quiet, low speed operation. They are ideal for exhausting hot or contaminated air streams, including smoke fumes, and are also suitable for general ventilation applications.
