Daikin-McQuay 330424001 Fan Blade

The Daikin-McQuay 330424001 is a high-performance 30-inch condenser fan blade engineered for heavy-duty HVACR applications. This 5-blade aluminum fan prop features a precision-calibrated 28-degree pitch designed to optimize static pressure handling and maximize CFM in large-scale industrial and commercial condensing units. Technical data confirms this assembly is the standard OEM replacement fan blade for several older 4-blade configurations that originally utilized a 35-degree pitch, providing improved rotational stability and reduced motor load without sacrificing airflow velocity.

Built with a 5/8-inch bore (.62") for secure integration with standard motor shafts, the 330424001 propeller is dynamically balanced to minimize vibration and prevent premature bearing wear on the condenser motor. For contractors performing field service, ensuring the correct blade position within the shroud is critical; maintaining a 1/3-above and 2/3-below placement is recommended to ensure the Daikin 30" fan achieves the designed heat rejection required for the refrigeration cycle. This HVAC replacement part is built to endure the high-torque demands of continuous cycle operations in demanding environments.

• Optimized Airflow: The 30-inch diameter and 5-blade geometric profile ensure high-volume air movement at lower noise levels compared to legacy 4-blade designs.
• Precision Pitch: A fixed 28-degree pitch provides the ideal balance between amperage draw and static pressure capability.
• OEM Compatibility: Specifically designed as an authentic Daikin-McQuay replacement part to ensure seamless fitment and system performance.
• Robust Construction: Manufactured for durability in harsh outdoor conditions, resisting environmental corrosion and mechanical fatigue.

Common Questions

Can I use this 5-blade fan to replace an original 4-blade prop?
Yes, the 330424001 is the designated technical replacement for previous 4-blade designs. While the original may have had a 35-degree pitch, this 5-blade, 28-degree pitch configuration provides equivalent cooling performance with improved mechanical efficiency.

What is the required bore size for the motor shaft?
This fan blade assembly requires a 5/8" (.62) diameter shaft. Always verify the motor shaft dimensions before attempting installation to ensure a proper fit.

Does rotation direction matter for this blade?
Yes, this is a Clockwise (CW) rotation blade. Using a blade with the incorrect rotation will result in reversed airflow and localized overheating of the condenser coil.
