Product Details
BSC Preferred's™ Series Industrial Roof Exhausters are engineered for general ventilation and smoke and fume removal, prioritizing lower cost and minimal maintenance. The kit includes a ruggedly constructed steel curb cap with a spun venturi section designed for efficient air flow. Features include standard cast aluminum spark-resistant propellers, suitable for hazardous locations when paired with an explosion-proof motor. The unit also features a butterfly damper section made of 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 on a stainless steel axle. Optional accessories consist of weatherproof non-fused disconnect switches, insulated roof curbs for flat or pitched roofs, magnetic latches to securely keep damper section lids down when the fan is off, and replacement damper sections.
