Trane FAN2777 Fan Blade

The Trane FAN2777 Fan Blade is a heavy-duty OEM replacement component engineered for high-static condenser and air handler applications. Designed with a 26-inch diameter and a precise 32-degree pitch, this 3-blade fan assembly ensures maximum cubic feet per minute (CFM) delivery while maintaining critical static pressure balance within Trane HVAC systems. For contractors performing a condenser fan motor service, matching these exact specifications is vital to avoid motor overheating or amp draw spikes that occur with incorrect blade geometry.

This unit features a 5/8" bore and is configured for CW rotation (clockwise), specifically balanced to minimize vibration and bearing wear on the motor. In industrial and commercial HVAC replacement parts scenarios, the FAN2777 provides the aerodynamic efficiency required to maintain factory-spec heat transfer across the coils. Professionals should verify the fan blade pitch and rotation from the discharge side to ensure full compatibility with existing Trane fan motors and shroud clearances.

• OEM Precision: Guaranteed fit for Trane condenser units, eliminating the need for field modifications or hub adjustments.
• Optimized Airflow: The 3-blade design and 32-degree pitch provide high-velocity air movement for superior thermal management.
• Reduced Mechanical Stress: Factory-balanced construction prevents harmonic resonance and extends the operational life of the motor bearings and shaft.
• Durable Metallurgy: Built to withstand high-duty cycles and environmental exposure common in rooftop and split-system applications.

• How do I confirm the rotation of the FAN2777? This blade is a CW rotation unit. Rotation is determined by viewing the fan from the air-discharge side (facing the motor shaft).
• Will this fit a 1/2" motor shaft? No, this blade is designed strictly for a 5/8" bore. Using a reducer bushing is not recommended for high-RPM HVAC applications due to balance risks.
• Why is the 32-degree pitch important? The pitch directly correlates to the motor's horsepower requirements. A 32-degree pitch ensures the system moves the correct volume of air without overloading the specified drive motor.
