Trane FAN1531 Fan Blade

The Trane FAN1531 is a high-performance HVAC condenser fan blade engineered for demanding outdoor heat rejection applications. This 26-inch, three-blade assembly features a precise 25-degree pitch, designed to maintain optimal static pressure and static efficiency in residential and light commercial units. Built with durable aluminum blades and a painted steel spider, the Trane replacement fan blade provides the structural integrity necessary to withstand high-velocity air movement and outdoor exposure without compromising balance or airflow volume.

For technicians performing a condenser fan motor repair, verifying the clockwise (CW) rotation and the standard 1/2-inch bore diameter is critical for a secure press-fit or set-screw mounting on the motor shaft. Matching the OEM Trane fan blade specifications ensures the system hits its designed CFM targets, preventing elevated head pressures that lead to compressor overheating and premature failure. This OEM cooling fan replacement is the professional choice for restoring factory-spec airflow and efficiency to compatible Trane and American Standard outdoor sections.

• Optimized Airflow: The 25-degree pitch is specifically calibrated for Trane condensers to maximize heat transfer across the coils.
• Durable Construction: Heavy-duty aluminum blades paired with a reinforced steel spider prevent blade "flexing" during high-RPM operation.
• Precision Balancing: Factory-balanced design minimizes vibration, reducing mechanical stress on the condenser fan motor bearings.
• Direct OEM Fit: Eliminates the guesswork associated with universal blades, ensuring correct shroud clearance and 1/2" shaft compatibility.

How do I confirm the rotation of the FAN1531?
This blade is Clockwise (CW) rotation when viewed from the discharge side (facing the air moving toward you). Always verify your motor's lead orientation before installation.

Will this blade fit a 5/8" motor shaft?
No, the Trane FAN1531 features a 1/2-inch hub bore. If your motor has a 5/8" shaft, you will require a different part number or a bore reducer, though OEM replacement is always recommended.

Why is the blade pitch important for my HVAC system?
The 25-degree pitch determines the load on the condenser motor. Using an incorrect pitch can either starve the coil of air or overload the motor, causing it to trip on thermal overload.
