Nordyne 667278R Fan Blade

Maintaining high-side head pressure requires a precise balance of velocity and static pressure, which is exactly why the Nordyne 667278R Fan Blade is the standard for localized air movement in residential condensers. This is the official updated replacement for the discontinued 667278, engineered with a 20-inch diameter and a specific 30-degree pitch. For contractors performing a field swap, the clockwise (CW) rotation and 1/2-inch bore ensure a direct fit onto standard 48-frame motor shafts without requiring a hub adapter. Constructed from galvanized steel with a secure aluminum hub, this 3-blade assembly is designed to withstand the high-torque startups of modern high-efficiency motors while minimizing vibration-induced stress on the motor bearings.

• Universal Compatibility: Serves as the factory-authorized update for part number 667278, fitting a wide range of Nordyne, Intertherm, and Miller outdoor units.
• Optimized Airflow: The 30-degree pitch is calibrated to move maximum CFM at standard RPMs, preventing compressor overheating during peak summer loads.
• Durable Construction: Features galvanized steel blades and an aluminum hub to resist corrosion in harsh outdoor environments.
• Direct Bore Fit: Standard 1/2" shaft hole simplifies the installation process for rapid field service.

• Is the 667278R a direct replacement for 667278? Yes, the "R" designation indicates the current manufacturer-spec updated version for the older 667278 model.
• How do I verify rotation? This blade is a Clockwise (CW) rotation part when viewed from the discharge air side (typically the top of the unit).
• What tools are recommended for installation? While a standard set screw secures the hub, we recommend using a hub puller for removing old, seized blades to avoid bending the motor shaft.
