Carrier LA04AA330 Fan Blade

The Carrier LA04AA330 Fan Blade is a heavy-duty OEM replacement fan blade designed for high-capacity industrial and commercial condenser units. Engineered for precision and static balance, this 30-inch diameter assembly features a three-blade configuration with a specific 18-degree pitch. These specifications ensure optimal CFM performance while maintaining low vibration levels to prevent premature motor bearing failure. As a factory-authorized part, it maintains the original engineering standards required for Carrier, Bryant, and Payne HVAC systems, providing a direct-fit solution for technicians servicing larger rooftop units or split systems.

Constructed from durable galvanized steel, the LA04AA330 is built to withstand the rigorous duty cycles of outdoor environments. The hub is designed for a 5/8" bore on the discharge side and operates with clockwise (CW) rotation. When performing a swap, verify that the hub placement matches the original propeller configuration to ensure proper airflow direction and motor load. This component is essential for maintaining the heat transfer efficiency of the condenser coil, directly impacting the system's overall refrigeration cycle stability and energy consumption.

• Precise 18-Degree Pitch: Optimized to deliver consistent static pressure and high-volume airflow across 30-inch condenser coils.
• Factory-Balanced 3-Blade Design: Reduces mechanical stress on the motor shaft and prevents cabinet resonance during high-RPM operation.
• Durable Steel Construction: Resists aerodynamic deformation and environmental corrosion for long-term reliability in commercial applications.
• Direct OEM Compatibility: Ensures an exact fit for 5/8" motor shafts, eliminating the need for field modifications or generic adapters.

• What rotation does the LA04AA330 use? This fan blade is designed for Clockwise (CW) rotation when viewing from the discharge side (the side opposite the motor).
• Is this compatible with a 1/2" motor shaft? No, this specific model is engineered for a 5/8" bore and will not fit a standard 1/2" shaft without an adapter, which is not recommended for this diameter.
• Where is the set screw located? The hub is positioned on the discharge side of the blade assembly to ensure secure fastening to the condenser motor shaft.
