Carrier LA01RA004 Fan Blade
The Carrier LA01RA004 Fan Blade is a critical condenser fan blade designed for specific Carrier, Bryant, and Payne outdoor units. Engineering specifications for this 4-blade aluminum fan include a 22-inch diameter with a 20-degree pitch, engineered to handle precise CFM requirements for high-efficiency heat pumps and air conditioners. This component utilizes a 1/2-inch bore designed for a clockwise rotation (CW) when viewed from the or discharge side. As a direct OEM replacement fan blade, the LA01RA004 ensures optimal head pressure management and motor longevity by maintaining the factory-specified static pressure balance. Replacing a warped or unbalanced blade with this precision HVAC motor fan prevents premature bearing failure in the condenser motor and ensures the system maintains its rated SEER performance. Field technicians should verify the hub location and set-screw alignment during installation to ensure proper clearance within the shroud and prevent vibration-induced noise.
Key Benefits for HVAC Contractors:- OEM Engineering: Ensures exact fan blade pitch and balance to meet factory BTU heat rejection standards.
- Durable Construction: Heavy-gauge aluminum blades resist corrosion and stress-cracking in harsh outdoor environments.
- Direct Compatibility: Eliminates the guesswork associated with universal blades, ensuring correct airflow CFM and amperage draw.
- Vibration Reduction: Factory-balanced design minimizes mechanical stress on the fan motor shaft and housing.
What is the correct rotation for the LA01RA004?
This blade is designed for Clockwise (CW) rotation when viewing the unit from the top or discharge side. Always verify the motor lead wiring to match this rotation.
Can I use a universal 22-inch blade instead of this OEM part?
While universal blades may fit the 1/2-inch shaft, the 20-degree pitch of the LA01RA004 is specific to the system's performance curve. Using an incorrect pitch can overload the motor or reduce heat transfer efficiency.
How do I ensure the blade is installed at the correct depth?
The blade should be positioned within the venturi or shroud according to the manufacturer's spec, typically centered to maximize suction and air throw across the coils.
