Lau 6128280001 Fan Blade

The Lau 6128280001 Fan Blade is a precision-engineered aluminum condenser fan blade designed for demanding HVACR applications. This 24-inch propeller features a 3-blade configuration with a 21-degree pitch, optimized for high-volume airflow across outdoor condensing units. Operating with a Clockwise (CW) rotation (viewed from the discharge side), it utilizes a 1/2-inch bore positioned on the discharge side for secure motor shaft integration. Constructed from heavy-gauge aluminum, the Lau 6128280001 is built to withstand environmental exposure while maintaining structural integrity during high-velocity operation. This OEM-spec replacement fan blade ensures proper heat dissipation by maintaining the static pressure requirements of the system. Contractors should verify the rotation and pitch to ensure HVAC fan blade compatibility with existing motor horsepower and RPM ratings. Proper alignment on the motor shaft is critical to prevent vibration and ensure long-term bearing life in the condenser motor.

Technical Specifications and Benefits

• Optimized Airflow: The 21-degree pitch is specifically calibrated for condenser fan blade replacement in residential and light commercial units.
• Durable Construction: High-grade aluminum blades resist corrosion and reduce the load on the motor due to their lightweight profile.
• Precise Fit: The 1/2" bore size and discharge side hub location allow for exact positioning within the fan shroud.
• System Reliability: Engineered to meet HVAC replacement parts standards for static efficiency and noise reduction.

Common Questions

How do I determine the rotation of this fan blade?
Rotation is determined by looking at the air discharge side. The Lau 6128280001 is a Clockwise (CW) rotation blade. Always match the rotation of your existing motor to avoid system overheating.

Can this blade be used in heat pump applications?
Yes, provided the 24-inch diameter, 21-degree pitch, and CW rotation match the original manufacturer’s specifications. It is a common condensing unit fan blade for various split systems.

Why is the pitch degree important for my condenser?
The pitch determines how much air the blade moves per revolution. Installing a blade with an incorrect pitch can overload the fan motor or fail to pull enough heat from the coils, leading to high head pressure.
