Dayton - Belt-Drive Panel Exhaust Fan 48 in Blade (1WDC4)

This belt-drive panel exhaust fan features a 48-inch steel blade and is designed for high airflow applications, supporting air movement from 14,214 cfm to 31,442 cfm depending on the motor used. The fan can be mounted vertically or horizontally on walls and is suitable for both air supply and air intake operations. Its belt-drive mechanism provides quieter operation and greater control over blade speed compared to direct-drive models. Constructed with a durable steel frame and zinc-plated finish, the fan is shipped unassembled and does not include a drive package, allowing compatibility with a range of motors and drive components. Ideal for industrial and commercial ventilation where high static pressure or airflow is required.
