Lau 60555901 Fan Blade

The Lau 60555901 Fan Blade is a professional-grade 18-inch propeller designed for high-efficiency free air and low-pressure ventilation applications. Engineered with a 23-degree pitch and a 3-blade configuration, this CW rotation fan blade ensures optimal CFM output while maintaining a manageable amp draw on your motor. Built for the rigors of field service, it features high-strength aluminum blades riveted to a robust steel spider, providing the structural integrity required to prevent blade tracking issues or vibration in industrial air circulators and exhaust units.

This HVAC replacement fan blade utilizes an interchangeable hub system, allowing contractors to adapt the propeller to various motor shaft diameters (such as 1/2", 5/8", or 3/4") using a standard Lau model 3F1823CW compatible hub. When auditing a system for a condenser fan blade replacement, verify that the 18" diameter and 23-degree pitch match your existing specs to avoid overloading the motor or under-cooling the coil. This "Free Air" type is specifically suited for applications where there is minimal static pressure, ensuring quiet and consistent performance for pedestal fans and window units.

• Durable Construction: High-quality aluminum blades and a reinforced steel spider resist corrosion and mechanical fatigue.
• Versatile Hub Compatibility: The interchangeable hub design allows for precise installation on multiple shaft sizes regardless of the motor brand.
• Optimized Performance: Specifically pitched at 23 degrees to balance airflow delivery with 825 or 1075 RPM motor profiles.
• Reduced Noise: Aerodynamically contoured blades minimize turbulence and audible decibel levels in residential or commercial settings.

What hub do I need for this fan blade?
The Lau 60555901 requires an interchangeable hub (sold separately). You must select the hub that matches your motor's shaft diameter (e.g., Lau 60765804 for a 1/2" shaft).

How do I determine the rotation?
Rotation is determined by looking at the discharge side (face) of the 18" fan blade. This model is Clockwise (CW) rotation.

Can I use this on a high-static pressure condenser?
This is a free air fan blade designed for low-pressure environments. For high-static condenser units, ensure your static pressure calculations align with a 3-blade 23-degree pitch profile to prevent motor overheating.
