Trane FAN3995 Fan Blade

The Trane FAN3995 Fan Blade is a critical performance component engineered for high-static condenser and air handler applications. This heavy-duty 23.4-inch diameter fan blade features a precision-stamped 2-blade swept design, specifically optimized to maximize airflow while reducing vibration and operational noise in residential and light commercial systems. With a 32-degree pitch and CCW rotation, it provides the necessary aerodynamic lift required for efficient heat rejection through the coil. The 1/2-inch hub bore ensures a secure fit on standard motor shafts, typically secured via a steel set screw for long-term reliability.

For technicians performing a direct Trane FAN3995 replacement, this component is frequently utilized in 3-ton condensing units and package systems. It is also identified as a direct replacement for D672907P19 and FAN3983. Using an OEM HVAC fan blade ensures that the motor remains within its specified amperage draw, preventing premature motor failure caused by improper blade weight or pitch. Installing a genuine condenser fan blade like the Trane FAN03995 maintains the system's SEER rating and factory cooling capacity.

• Precision Airflow: The 32-degree blade pitch is calibrated for optimal cubic feet per minute (CFM) output.
• OEM Compatibility: Fits a wide range of models including 4WCX3036, 4DCY4036, and 4YCX3036 units.
• Durable Construction: Made with high-grade aluminum blades and a robust steel hub for resistance to environmental fatigue.
• Static Balance: Factory-balanced to reduce stress on the 1/2-inch bore motor shaft and extend motor bearing life.

Common Questions

What is the correct rotation for the FAN3995?
This blade is designed for CCW (Counter-Clockwise) rotation as viewed from the lead end of the motor or the discharge side of the fan. Always verify rotation before securing the hub to avoid reversing airflow.

Will this work on a 5/8-inch motor shaft?
No, this specific part features a 1/2-inch bore. For 5/8-inch shafts, an alternative hub size or a different part number is required to ensure a proper mechanical connection.

Can I use this to replace a 3-blade or 4-blade assembly?
It is recommended only as a direct Trane OEM replacement for units originally spec'd with a 2-blade, 23.4-inch assembly. Changing the blade count or pitch will alter the motor load and may cause the thermal overload to trip.
