Carrier LA04RA301 Fan Blade

The Carrier LA04RA301 Fan Blade is a critical OEM replacement engineered for high-capacity condenser units requiring precise airflow management. This heavy-duty propeller fan features a 30-inch diameter and a 32-degree pitch, optimized to meet the static pressure requirements of Carrier, Bryant, and Payne 09DE series equipment. Constructed with durable steel blades, this 3-blade assembly ensures structural integrity under high-velocity conditions, effectively preventing blade deformation that can lead to motor over-amping.

Designed for clockwise (CW) rotation (facing discharge), the LA04RA301 includes a 5/8-inch bore specifically positioned on the discharge side for a secure fit on standard motor shafts. Replacing an imbalanced or pitched-out blade with this factory authorized part is essential for maintaining original system efficiencies and subcooling targets. As a direct successor to the LA04RA300, this component restores factory-spec decibel levels and prevents the premature bearing wear often associated with generic, off-pitch alternatives. For field technicians, ensuring the set screw is torqued onto the shaft flat is mandatory to maintain the aerodynamic balance of this 22-lb assembly.

• Precise Airflow Calibration: The 32-degree pitch and 30-inch diameter are calculated to maintain the necessary CFM for optimal heat rejection.
• OEM Structural Integrity: Heavy-duty steel construction resists the "wing-flap" effect, ensuring consistent performance throughout the cooling season.
• Vibration Mitigation: Factory-balanced blades eliminate the mechanical stress that causes premature failure of the condenser fan motor.
• Direct Cross-Compatibility: Engineered as the exact replacement for LA04RA300, guaranteeing a hassle-free drop-in installation without hardware modifications.

• What rotation and bore size does this blade require? This blade is designed for CW rotation and features a 5/8" bore on the discharge side.
• Will this blade fit my specific 09DE model? The LA04RA301 is the standard 30" propeller for numerous Carrier and Bryant commercial and residential split systems; always verify your model number via the service manual.
• Should I replace the capacitor at the same time? Technicians recommend testing the run capacitor whenever replacing an imbalanced fan blade to ensure the motor starts under the correct electrical load.
