Daikin-McQuay 049121701 Fan Blade

The Daikin-McQuay 049121701 Fan Blade is a precision-engineered OEM replacement condenser fan designed for high-performance heat rejection in commercial and residential HVAC units. Featuring a 24-inch diameter and a 3-blade configuration, this aluminum propeller is balanced to minimize vibration and extend the service life of the fan motor. It is built with a 1/2 inch bore (hub size) and operates with a Clockwise (CW) rotation, ensuring optimal airflow across the condenser coils to maintain critical system pressures. This part is a direct technical equivalent for several legacy McQuay and Leader Fan Industries models, including part number 1B455, making it a reliable solution for restoring factory-standard efficiency to cooling systems.

• Direct OEM Fit: Drop-in replacement for Daikin-McQuay 049121701 and 1B455, ensuring exact mechanical compatibility without field modifications.
• High-Strength Construction: Manufactured with corrosion-resistant materials to withstand harsh outdoor environments and prevent blade pitching or warping.
• Optimized Airflow: The 3-blade design is pitched specifically for condenser motor applications where consistent CFM is required for heat transfer.
• Vibration Reduction: Factory-balanced to protect motor bearings and reduce acoustic resonance during high-load operation.

• What is the rotation of this blade? This fan blade is designed for Clockwise (CW) rotation when viewing the discharge side.
• Will this fit a 48-frame motor? Provided the motor shaft is a 1/2" diameter, this blade will seat correctly; always verify shaft length and clearance within the fan shroud.
• What are the signs of a failing fan blade? Technicians should look for hairline cracks at the hub, bent trailing edges, or excessive vibration during the start-up cycle.
