12 Inch 3 Phase Industrial Fan

This Dayton exhaust and supply fan moves air in commercial and industrial spaces where three-phase power is available. The direct-drive reversible design allows airflow direction to be changed without rewiring ductwork. It suits facilities that need a compact unit for ventilation or make-up air.

Ball Bearing Motor and Compact Housing

A totally enclosed air-over motor with ball bearings runs at up to 104 degrees F ambient temperature. The 16 by 16 inch frame with 14 1/16 inch depth fits tight mechanical rooms and standard curb mounts. Voltage options of 208-230 or 460 volts AC let the installer match existing three-phase panels.

Replaces Belt Drive Units in Existing Curbs

This fan upgrades older belt-driven models that require pulley maintenance and larger housings. The jump is worth it when downtime for belt changes is costly or when the motor enclosure must resist dust and moisture. Buyers who need variable speed control or single-phase operation should look elsewhere.
