The Blodgett 5001 blower wheel moves air through compatible commercial ovens as part of the circulation assembly. Its counterclockwise rotation directs airflow when driven by the oven's blower motor, supporting even distribution throughout the cooking chamber. The wheel measures 9-7/8 inches in diameter and 2-1/8 inches wide, with a puller hub configuration. https://partsfe.com/blower-wheel9-78d-x-2-18w-58-for-blodgett-part-5001/1-5001.html
