Product Details
BSC Preferred's™ Series industrial roof exhausters are engineered for general ventilation and smoke and fume removal, prioritizing lower cost and reduced maintenance. The units feature a ruggedly constructed steel curb cap with a spun venturi section to ensure efficient air flow, while standard cast aluminum spark-resistant propellers make them suitable for hazardous locations when used with an explosion-proof motor. The butterfly damper section is constructed from mill galvanized materials, with damper blades that open when the fan is energized and close weathertight when the unit is off; these dampers rotate in nylon bearings mounted on a stainless steel axle. Optional accessories available for these exhausters include weatherproof non-fused disconnect switches, insulated roof curbs for flat or pitched roofs, magnetic latches to secure damper section lids when the fan is off, and replacement damper sections.
