Carrier LA01RA339 Fan Blade
The Carrier LA01RA339 Fan Blade is a precision-engineered OEM replacement condenser fan blade designed for high-performance heat rejection in residential and light commercial HVAC systems. This 26-inch diameter fan blade features a 29-degree pitch and a 3-blade configuration, optimized to move maximum CFM while maintaining low static pressure across the coil. Engineered for durability, it utilizes a 1/2-inch bore and is designed for clockwise (CW) rotation (facing the discharge side). When performing a condenser motor replacement, ensuring blade pitch accuracy is critical to prevent motor overloading or insufficient subcooling. This Carrier replacement part is built with rigid materials to resist flexing under high-load conditions, making it a reliable choice for restoring factory-spec airflow. Proper fan blade pitch and balance are essential for reducing vibration and extending the service life of the fan motor bearings and overall system efficiency.
Key Benefits- Optimal Airflow Delivery: The 29-degree pitch provides the exact blade angle required for Carrier condenser units to maintain design-spec head pressures.
- Heavy-Duty Construction: Sturdy 3-blade design resists structural fatigue often caused by extreme temperature cycling and outdoor exposure.
- Precision Bore Alignment: The 1/2-inch hub ensures a secure fit on the motor shaft, reducing the risk of wobbling or catastrophic mechanical failure.
- Direct OEM Compatibility: Eliminates the guesswork associated with universal blades, ensuring the motor amperage draw remains within safe operating limits.
How do I verify the rotation direction for this blade?
The LA01RA339 is a clockwise (CW) rotation blade. In the HVAC industry, rotation is typically determined by looking down at the discharge side of the blade or the lead end of the motor.
What happens if the pitch angle is off on a replacement blade?
Installing a blade with an incorrect pitch will change the load on the motor. Too much pitch increases amp draw and can lead to motor burnout, while too little pitch results in poor heat exchange and high head pressure.
Is it necessary to replace the hub when I replace this fan blade?
This unit features an integrated hub designed for a 1/2-inch shaft. Always inspect the motor shaft for burs or corrosion and ensure the set screw is seated on the flat portion of the shaft for a secure mechanical connection.
