Dayton - Belt Drive Centrifugal Downblast Roof Exhaust Fan (2RB63)

This belt drive centrifugal downblast roof exhaust fan is designed for clean air applications, efficiently exhausting odorous, hot, or stale air from industrial and commercial buildings. It features a 13-1/4 inch aluminum wheel and comes fully assembled with a drive package, including motor, sheaves, belts, and bushings. The belt-drive configuration offers quieter operation and greater control over blade speed and airflow compared to direct-drive models. Constructed with a spun aluminum housing and backward inclined wheel, it is suitable for roof curb mounting and can handle maximum inlet air temperatures up to 180°F. The fan is ideal for environments requiring reliable, high-volume air movement and is compliant with AMCA Sound and Air standards.
