Know before you buy
Check your current blower wheel for the part number 70-20218-03 or verify that your motor shaft has a 1/2-inch diameter. Since this is a specific Rheem replacement part, it is designed to fit standard efficiency furnaces that require a clockwise rotation.
The concave shape is engineered to improve airflow efficiency and structural integrity within the blower housing. This design helps the wheel move air more effectively across the 48 blades, ensuring your furnace operates at its intended performance level.
Yes, this unit includes one set screw to secure the wheel to your blower motor shaft. Ensure your existing shaft is clean and free of debris before sliding the new wheel on to ensure a secure fit.
No, this blower wheel is specifically designed for clockwise (CW) rotation. Installing a wheel with the incorrect rotation direction will significantly reduce your furnace's airflow and may cause the motor to overheat.
Yes, this component is compatible with furnaces fueled by natural gas, propane, oil, or electricity. As long as your furnace housing matches the 10-inch by 10-inch nominal size and requires a clockwise rotation, it will function correctly regardless of the fuel source.
