Trane FAN4002 Fan Blade

The Trane FAN4002 Fan Blade is a precision-engineered OEM replacement part designed for high-performance heat transfer in residential and light commercial condensing units. This 23-inch diameter fan blade features a 22-degree pitch and a 3-blade configuration, optimized to move high volumes of air while maintaining motor efficiency. Engineered with a 1/2-inch bore and designed for CCW rotation (counter-clockwise), this aluminum component ensures a direct fit for professional HVAC repair and maintenance. As a veteran-grade Trane fan blade replacement, the FAN4002 supersedes several older part numbers, including FAN3070 and FAN3126, making it a critical stock item for condenser fan motor service. The robust spider hub and aluminum blade construction provide the necessary balance and durability to withstand high-static outdoor environments. When performing an AC tune-up or emergency service, verifying the FAN4002 specifications against the data plate is essential for ensuring peak system airflow efficiency and preventing premature motor bearing failure.

• Direct OEM Compatibility: Ensures seamless integration with Trane and American Standard units, eliminating the need for field modifications.
• Optimized Airflow: The 22-degree pitch is calibrated to maximize CFM output while keeping the condenser fan motor within its rated amperage.
• Superior Construction: High-grade aluminum blades with a 0.50" steel set screw hub provide long-term corrosion resistance and structural integrity.
• Broad Application: Replaces multiple legacy part numbers (FAN03126, FAN03070, D153886P44), simplifying inventory management for service trucks.

What is the correct rotation for the FAN4002?
This blade is designed strictly for CCW rotation (counter-clockwise) when viewing from the discharge side (lead end of the motor).

Which motor shaft size is compatible with this blade?
The Trane FAN4002 is engineered for a 1/2-inch bore shaft, common in standard 48-frame condenser fan motors.

Can I use this blade to replace a 4-blade or 2-blade version?
No. It is critical to match the blade count and pitch to the original OEM part to prevent motor overheating and ensure the correct refrigerant head pressure.
