Supco fb665 Fan Blade 6.625 in 5-blade Cw Vent Hood

Product Description

The SUPCO fb665 is a lightweight plastic replacement fan blade designed for use in ducted and non-ducted vent hood applications. The five-blade assembly measures 6.625 inches in diameter with a 12-degree pitch and clockwise rotation. It mounts on a 7/32-inch shaft and delivers standard airflow volume suited to typical residential and light commercial range hood installations. Its plastic construction keeps the rotating assembly light, reducing stress on the motor during operation. HVAC technicians and appliance service professionals install this blade as a direct replacement when the original blade is cracked, chipped, warped, or out of balance.

The fb665 is suited for vent hood systems, both ducted configurations that exhaust air outside the structure and non-ducted recirculating configurations that filter and return air to the kitchen. The 12-degree blade pitch and clockwise rotation are matched to standard vent hood fan motor configurations found in residential kitchens. This blade is a common service part called upon during routine appliance repair calls where blade damage or motor replacement requires a new blade assembly.

Installation Notes

Installation should be performed by a qualified appliance technician or HVAC service professional. Disconnect power to the vent hood at the circuit breaker before removing any components. Ensure the replacement blade rotation direction and shaft bore match the existing motor before securing the blade to avoid vibration or airflow reversal. Verify the blade seats fully and securely on the shaft before restoring power.
