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 unit features a ruggedly constructed steel curb cap with a spun venturi section for efficient air flow. Standard components include cast aluminum spark-resistant propellers, making them suitable for hazardous locations when paired with an explosion-proof motor. The butterfly damper section is made from mill galvanized construction, with damper blades that open when the fan is energized and close weathertight when the unit is off. The dampers rotate in nylon bearings mounted on a stainless steel axle. Optional accessories are available, including 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.
