Continental-050214-body.jpgContinental Fan’s UDVL Upblast Roof Ventilators are designed to provide aerodynamically efficient performance and a low silhouette design. The ventilators are constructed with a heavy duty welded steel base, galvanized butterfly damper section, and a spark resistant cast aluminum airfoil axial impeller. The UDVL direct drive low silhouette upblast roof ventilator requires no belts or pulleys, and is ideal where little or no maintenance is required. The fan is available in diameters from 18 in through 60 in, with capacities ranging to 54,000 cfm. Other features of the fan include a TEFC industrial duty motor, weather-tight steel curb panel, air dried enamel paint finish, and damper rods that turn in nylon bearings and require no lubrication.
