Dayton Centrifugal Downblast Roof Exhaust Fan: Belt Drive, Includes Drive Pack

The Dayton Centrifugal Downblast Roof Exhaust Fan is used for general clean-air exhaust ventilation on commercial or industrial roofs. It is designed for belt-drive operation and includes a drive package, making it suitable for moving moderate volumes of air in applications such as warehouses, factories, or assembly areas where high static pressure is not required.

The Dayton 7AU74 features a 24 1/2-inch wheel, delivers 5,395 cfm, and is powered by a single-speed open dripproof motor rated at 208-230/460V AC. It is a belt-drive, unassembled unit with a square base for roof mounting. Exhaust airflow ranges from 5,000 to 10,000 cfm at 0.000 in SP and 2,000 to 4,999 cfm at 0.500 in SP.
