Daikin-McQuay 073061402 Fan Blade

The Daikin-McQuay 073061402 Fan Blade is a critical 28-inch replacement component engineered for high-static pressure applications in commercial HVAC units. This heavy-duty condenser fan blade features a specific pitch and bore configuration designed to maintain optimal CFM delivery while minimizing motor amp draw. It is a direct OEM replacement for several McQuay rooftop unit parts and chiller systems, ensuring balanced operation and reduced vibration that protects the motor bearings and mounting brackets. When performing a commercial AC fan blade replacement, the precision-stamped hubs on this assembly provide a secure fit on the motor shaft, preventing slippage during high-torque startup. Contractors should verify the rotation direction and hub placement against the existing Daikin HVAC blower assembly to ensure proper airflow across the condenser coils. Using this genuine HVAC replacement fan blade helps restore factory-spec heat transfer efficiency and prevents premature compressor failure caused by inadequate airflow.
