Trane FAN1820 Fan Blade

This Trane FAN1820 Fan Blade is a critical direct-fit component for maintaining high-efficiency heat transfer in commercial and industrial condensing units. Featuring a 24-inch diameter and a precise 22-degree pitch, this 3-blade assembly is engineered for heavy-duty CW (Clockwise) rotation. The 1/2-inch hub bore ensures proper seating on standard motor shafts, providing the structural integrity needed to handle high-static pressure environments without blade deformation.

For contractors performing maintenance or emergency repairs, the Trane FAN1820 offers a reliable solution to restore optimal CFM (Cubic Feet per Minute) airflow. Constructed from durable galvanized steel, these blades are balanced to minimize vibration, which protects the motor bearings and reduces specialized tool requirements during installation. When replacing a condenser fan blade, ensure the rotation and pitch match your existing Trane part number to prevent motor overheating and maintain system performance across the coil.

Key Benefits

• Optimized Airflow: The 22-degree blade pitch is specifically calibrated to maximize air volume while maintaining low noise levels.
• Industrial Durability: Engineered for high-duty cycles in Trane HVAC systems, ensuring resilience against structural fatigue.
• Direct OEM Replacement: Eliminates the guesswork for technicians by providing a precise match for 24-inch fan blades with a 1/2-inch bore.
• Balanced Performance: Factory balancing reduces radial load on the fan motor, extending the operational life of the entire drive assembly.

Common Questions

How do I verify the rotation for my system?
The Trane FAN1820 is a Clockwise (CW) rotation blade. Always determine rotation by looking down at the discharge side of the fan or the "lead" edge of the blade to ensure it matches your motor's specifications.

What are the signs that a fan blade needs replacement?
Excessive vibration, visible stress cracks near the hub, or rhythmic banging often indicate a failing blade. Even minor bends can lead to catastrophic motor failure or coil damage if not addressed.

Will this fit any 1/2-inch motor shaft?
While the 1/2-inch bore is standard, this blade is specifically designed for Trane industrial units requiring a 24-inch diameter and 22-degree pitch. Always verify the part number against your unit's data plate.
