This is a direct-fit replacement propeller pulley for 48" PolarCool evaporative cooling fans. If your fan's pulley is worn, cracked, or slipping, this restores proper power transmission from motor to propeller and gets your airflow back to spec.
The 1011-0100 pulley is a genuine PolarCool replacement component built to keep 48" evaporative cooling fans running at rated airflow. It's a common wear item in warehouse cooling, outdoor cooling, and industrial air cooler setups where belts and pulleys see continuous duty cycles.
