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

The Dayton 7AX55 is a belt-drive roof exhaust fan designed for clean air applications. It removes stale air, fumes, or heat from industrial and commercial buildings, mounting directly on the roof. With 2,791 cfm airflow, it suits general ventilation in warehouses, factories, or assembly areas where high static pressure is not required.

The Dayton 7AX55 features a 16 3/4 in wheel, delivers 2,791 cfm, and operates on 115/208-230V AC with a single-speed, open dripproof motor. It includes a drive package, has a square base, and is unassembled. The motor is standard-efficiency; no high-efficiency option is available. It is not for high-static-pressure applications.
