Daikin-McQuay 330294011 Fan Blade

The Daikin-McQuay 330294011 Fan Blade is a critical 30-inch diameter condenser component designed for high-static pressure applications in commercial HVAC systems. This heavy-duty condenser fan blade is the direct engineering replacement for the legacy 330294001 part number, ensuring seamless mechanical integration without field modifications. Engineered for optimal CFM performance, this puller-style propeller maintains precise pitch and balance to reduce vibration and extend the service life of the fan motor bearings. When performing a McQuay chiller repair or rooftop unit maintenance, utilizing this OEM-specified replacement HVAC fan blade ensures the refrigeration circuit maintains proper head pressure and heat rejection rates. Contractors should verify bore size and hub orientation during installation to ensure peak aerodynamic efficiency. This industrial HVAC component is built to withstand the rigors of continuous operation in demanding outdoor environments, making it the primary choice for restoring airflow integrity to large-tonnage McQuay and Daikin equipment.

Key Benefits for Technicians:

• Direct OEM Interchange: Replaces 330294001 with identical mounting specs and aerodynamic profiles.
• High Volume Airflow: The 30-inch diameter design is optimized for high-capacity heat exchangers.
• Balanced Construction: Factory-set pitch reduces mechanical resonance and prevents premature motor failure.
• Durable Material: Constructed for long-term resistance against environmental corrosion and blade flexing.

Frequently Asked Questions:

Is the 330294011 a direct swap for the older 330294001 model?
Yes, the 330294011 is the updated manufacturer-specified replacement, maintaining all dimensions and performance characteristics of the 330294001.

What are the critical dimensions for this fan blade?
This is a 30-inch diameter fan blade. Before installation, confirm the hub bore size and setscrew configuration match your existing motor shaft.

Why is OEM propeller balance important in McQuay units?
Using a genuine Daikin-McQuay fan blade ensures the assembly operates within specific RPM tolerances, preventing excessive noise and protecting the motor’s internal components.
