Trane FAN3748 Fan Blade
Ensure peak performance in residential condensing units with a genuine Trane FAN3748 Fan Blade. Designed for optimal heat transfer, this 19-inch diameter component is essential for maintaining the subcooling and head pressure levels required for efficient cooling. Built from durable aluminum, this 3-blade propeller features a precision-engineered 31-degree pitch to maximize CFM while minimizing motor load. As a direct Trane OEM replacement part, it installs seamlessly onto standard 1/2" motor shafts, eliminating the alignment issues common with universal aftermarket blades. The counter-clockwise (CCW) rotation is specifically calibrated for Trane and American Standard outdoor sections, ensuring correct airflow direction across the condenser coils. Whether you are performing a seasonal tune-up or responding to a vibration-related service call, this condenser fan blade provides the structural integrity and aerodynamic balance needed to prevent premature motor bearing failure and reduce operational noise.
Key Benefits:- Precision Aerodynamics: The 31-degree pitch is optimized for high-static environments, ensuring consistent airflow through dirty or high-density coil fins.
- OEM Compatibility: Guaranteed fit for specific Trane and American Standard models, including 2A7A, 2TWB, and 4TTM series units.
- Corrosion Resistance: Lightweight aluminum construction resists environmental degradation, maintaining balance over long-term outdoor exposure.
- Standardized Bore: Features a 1/2" hub bore size for a secure, slip-free connection to HVAC replacement motors.
- How do I confirm the rotation of my existing fan? This blade is CCW Rotation (looking from the discharge side). Always verify the rotation matches your motor's nameplate to avoid reversing airflow.
- Does this include the hub and set screw? Yes, this is a complete fan blade assembly with an integrated hub designed for standard 1/2-inch shafts.
- What causes these blades to fail? Stress fractures from unbalanced motors or hail damage are common. Replacing a bent blade immediately prevents vibration that can destroy the condenser fan motor.
