Product Details
BSC Preferred's® Series Industrial Roof Exhausters are designed for general ventilation and smoke and fume removal, prioritizing lower cost and reduced maintenance. The kit includes a ruggedly constructed steel curb cap featuring a spun venturi section for efficient airflow, and standard cast aluminum spark-resistant propellers that are suitable for use in hazardous locations when paired with an explosion-proof motor. The exhausters are equipped with a butterfly damper section constructed from mill galvanized material, with damper blades that open when the fan is energized and close weathertight when the unit is off. The dampers rotate in nylon bearings on a stainless steel axle. Optional accessories include weatherproof non-fused disconnect switches, insulated roof curbs for flat or pitched roofs, magnetic latches to keep damper section lids down when the fan is off, and replacement damper sections.
