Trane FAN4078 Fan Blade

The Trane FAN4078 is a high-performance, 3-blade condenser fan engineered for heavy-duty industrial and commercial HVACR applications. This OEM Trane replacement fan features a 29" diameter and a 23-degree blade pitch, specifically designed to optimize static pressure and maximize airflow across condenser coils. Operating with a clockwise (CW) rotation and a 7/8" bore, this component ensures a precise fit for high-torque motors. As a technician focusing on field reliability, note that the FAN4078 replaces the Trane FAN3061; however, the FAN4078 utilizes a larger diameter, so checking shroud clearance is mandatory before installation. Constructed for durability in demanding environments, this condenser motor fan blade maintains system efficiency and prevents compressor overheating by ensuring consistent thermal exchange. Whether you are servicing Trane rooftop units or air-cooled chillers, this part provides the exact mechanical balance required to minimize vibration and bearing wear.

• Optimized Airflow: The 23-degree pitch moves high volumes of air efficiently, reducing head pressure on the compressor.
• OEM Compatibility: Designed as a direct replacement for FAN3061, ensuring electrical and mechanical synchronization with existing Trane HVAC systems.
• Balanced Construction: Heavy-duty 3-blade design reduces rotational noise and extends the service life of the fan motor bearings.
• Industrial Grading: Engineered to withstand the high-temperature conditions typical of commercial condenser units.

• What is the difference between FAN4078 and FAN3061? While the FAN4078 is the official superseding part, it has a larger 29" diameter compared to the older model. Verify your housing dimensions to ensure proper clearance.
• Does this fan blade include the hub set screw? Most OEM fan blades come with the necessary integrated hub for a 7/8-inch shaft, though reusing the existing motor shaft key may be required depending on the motor configuration.
• How do I confirm the rotation? This assembly is CW rotation (clockwise) when viewed from the discharge side (opposite the motor). Installing a blade with incorrect rotation will result in immediate system performance failure.
