Lau 6130630001 Fan Blade

Replacing a worn-out propeller in an outdoor condensing unit requires precise mechanical specs to ensure motor longevity and optimal heat transfer. The Lau 6130630001 Fan Blade is a heavy duty condenser style fan blade engineered for high-performance HVAC ventilation. Featuring a 20-inch diameter and a 31-degree pitch, this 3-blade aluminum propeller is designed for clockwise (CW) rotation. The 1/2" bore is positioned on the discharge side, ensuring a secure fit on standard condenser fan motor shafts. Unlike standard residential blades, this high-pitch configuration moves a significant volume of air to maintain head pressure in demanding cooling cycles. When sourcing Lau replacement parts, verifying the fan blade pitch and diameter is critical; an incorrect pitch can overload the motor or lead to insufficient subcooling. This rugged component provides a reliable solution for contractors needing to restore system efficiency in commercial or residential split systems.

• Optimized Airflow: The 31-degree pitch is specifically calibrated for high-static pressure environments typical of condenser coils.
• Corrosion Resistance: Constructed with high-strength aluminum blades and a durable spider to withstand harsh outdoor elements.
• Direct Compatibility: Standard 1/2" bore size allows for seamless integration with most 48-frame and 56-frame motors.
• Heavy-Duty Build: Reinforced design prevents blade flexing at high RPMs, reducing vibration and noise.

How do I confirm the rotation of my existing fan blade?
Rotation is determined by looking at the discharge side of the blade. This unit is CW rotation, meaning it turns clockwise when viewed from the air-discharge side. Always match the rotation of your condenser fan blade replacement to your motor's lead orientation.

Will a 31-degree pitch affect my motor's amp draw?
Yes. A higher pitch increases the load on the motor. Ensure your fan motor specifications can handle the torque required for a 31-degree 3-blade propeller to avoid overheating the windings.

What is the importance of the "Bore on Discharge Side" specification?
This indicates where the hub is located relative to the airflow. For the Lau 6130630001, the hub is on the side where air exits, which is a standard configuration for many outdoor HVAC units.
