Trane FAN3657 Fan Blade

The Trane FAN3657 Fan Blade is a heavy-duty OEM replacement fan blade designed for precision airflow management in Trane and American Standard condenser units. Featuring a 23-inch blade diameter and a dual-blade swept configuration, this aluminum component is engineered to maintain optimal static pressure and heat dissipation across the condenser coils. The 24.5-degree pitch is factory-calibrated for high-efficiency air movement, ensuring the motor operates within its designed amperage range to prevent overheating or premature failure. Built with a 1/2-inch hub bore and a counter-clockwise (CCW) rotation (as viewed from the discharge side), this part is a direct drop-in for technicians performing HVAC condenser fan blade replacement in the field. The aluminum blade construction and steel spider hub provide the structural rigidity needed to eliminate vibrations and ensure a balanced rotation at high RPMs. Before installation, contractors should verify the shaft size and rotation direction to ensure seamless integration with the existing condenser motor.

• Optimized Airflow Architecture: The Trane 2-blade fan configuration with a 24.5-degree pitch maximizes CFM output while maintaining a stable load on the motor.
• Vibration-Damping Design: Constructed with a high-strength aluminum alloy and a reinforced steel spider to ensure a balanced, noise-free operation in residential and commercial applications.
• Precision Fitment: Featuring a standard 1/2-inch bore, this blade allows for a secure mount to the motor shaft, reducing the risk of component loosening or hazardous mechanical failure.
• Corrosion Resistance: The aluminum material is specifically chosen for exterior HVAC environments, resisting oxidation even in high-humidity conditions.

• How do I confirm the rotation of my existing fan blade? Rotation for the FAN3657 is CCW (counter-clockwise) when viewed from the air discharge side. Always match the rotation to your unit’s motor specifications to avoid pushing air in the wrong direction.
• Is the set screw included with this blade? Yes, this condenser fan blade typically includes a steel set screw for securing the hub to the 1/2-inch motor shaft.
• Can I use this on a 3-blade or 4-blade system? It is critical to replace your component with the exact specified blade count and pitch. Swapping a 3-blade for a 2-blade can change the static pressure and cause the motor to over-amp or fail.
