Lau 60835301 Fan Blade

The Lau 60835301 Fan Blade is a professional-grade 5-blade condenser propeller engineered for high-static pressure applications in industrial air circulators and HVAC exhaust units. Featuring an 8-inch diameter and a 24-degree pitch, this component is designed to move air effectively while maintaining operational stability at speeds up to 3600 RPM. The aluminum blade construction and corrosion-resistant spider ensure structural integrity in demanding environments, preventing the flex or imbalance often seen with standard residential-grade propellers.

This counter-clockwise (CCW) rotation fan blade utilizes a 1/4" bore with an aluminum fixed hub, providing a precise fit for matching motor shafts. For technicians performing condenser fan motor replacement, matching the exact pitch and diameter is critical to prevent motor overloading or insufficient heat dissipation across the coils. This Lau 60835301 model serves as a reliable performance component for ventilation system maintenance and heavy-duty cooling equipment repair.

Key Benefits for Technicians:

• High-Speed Capacity: Rated for up to 3600 RPM, allowing for versatile use across high-velocity industrial exhaust fans.
• Optimized Airflow: The 24° blade pitch is calibrated to balance air volume (CFM) with motor torque requirements, ensuring efficient system cooling.
• Durability: Lightweight aluminum construction reduces start-up load on the motor bearings, extending the service life of the drive system.
• Standard Fitment: The 1/4-inch bore accommodates common small-frame motor shafts used in commercial refrigeration and specialized HVAC units.

Common Technical Questions:

How do I verify the rotation for this Lau blade?
Rotation is determined by viewing the blade from the discharge side (the air blowing toward you). This model is CCW (Counter-Clockwise). Installing a blade with incorrect rotation will significantly reduce airflow and can cause the compressor to trip on high pressure.

Can I use this in an outdoor condensing unit?
Yes, the aluminum blades and corrosion-resistant center spider are designed to withstand moisture and environmental exposure typical of outdoor condensing units and industrial vents.

What happens if the pitch does not match my original blade?
Increasing the pitch beyond 24 degrees can increase the AMP draw on your motor, potentially leading to thermal overload. It is recommended to match the original Lau specifications for optimal performance.
