Trane FAN2778 Fan Blade

The Trane FAN2778 Fan Blade is a critical replacement component designed for high-performance residential and light commercial condenser units. Featuring a 26-inch diameter and a precise 32-degree pitch, this 4-blade assembly is engineered to optimize airflow and heat dissipation in demanding HVAC condenser fan motor applications. The 5/8" bore ensures a secure fit on standard motor shafts, while the clockwise (CW) rotation profile meets specific OEM requirements for Trane and American Standard outdoor sections. Constructed with durable aluminum blades and a reinforced steel spider, this component withstands the rigors of 1725 RPM operation, maintaining balance and reducing vibration-induced stress on the motor bearings. For technicians performing HVAC part replacement, the FAN2778 provides the exact static pressure performance needed to maintain system efficiency and prevent high-head pressure trips during peak summer loads.

• OEM Compatibility: Exact replacement for Trane FAN2778 and FAN02778, ensuring proper CFM delivery without modifying the fan shroud.
• Optimized Pitch: The 32-degree blade angle is calibrated for maximum heat transfer efficiency in high-ambient environments.
• Industrial Build: Heavy-duty aluminum construction resists corrosion, extending service life in coastal or high-humidity regions.
• Precise Balance: Factory-balanced 4-blade design minimizes mechanical noise and prevents premature motor failure.

Is the Trane FAN2778 compatible with 5/8 inch motor shafts?
Yes, this fan blade is specifically designed with a 5/8" bore size to accommodate standard heavy-duty condenser fan motor shafts frequently found in 5-ton and larger residential units.

How can I verify the rotation direction before installation?
The Trane FAN2778 is a Clockwise (CW) rotation blade. Technicians should verify rotation by viewing the hub side of the fan to ensure it matches the existing motor’s lead configuration.

Will this blade improve system static pressure?
By utilizing the original 32-degree pitch, this blade restores the manufacturer-specified airflow, which is essential for maintaining correct subcooling and head pressure levels in the refrigerant circuit.
