Marvair 30135 Fan Blade

The Marvair 30135 Fan Blade is a heavy-duty OEM replacement engineered for critical thermal management in commercial and industrial HVAC condenser units. Featuring a 24-inch diameter and a 4-blade configuration, this component is designed to maintain high-velocity airflow across condenser coils to ensure proper refrigerant heat rejection. With a precision-stamped 20-degree pitch, the Marvair 30135 balances static pressure requirements with motor load efficiency, preventing premature compressor wear caused by insufficient cooling. This HVAC condenser fan blade is manufactured to rigorous tolerances to minimize vibration and bearing stress on the fan motor. For technicians servicing Marvair wall-mount units or specialized telecommunications cooling systems, using this genuine 30135 assembly ensures the system operates within original factory specifications for CFM output and decibel ratings.

• Stressed-Skin Blade Design: Optimized for high-ambient environments found in HVAC condenser units.
• Exact Pitch Matching: The 20-degree pitch ensures accurate airflow without overloading the condenser fan motor.
• OEM Compatibility: Guaranteed fit for Marvair systems requiring a 24" 4-blade fan blade, reducing field modification time.
• Corrosion Resistance: Built to withstand outdoor exposure and maintain structural integrity during high-RPM cycles.

What is the direction of rotation for the Marvair 30135?
Rotation is determined by the pitch; this 24-inch fan blade must be matched to your specific motor's lead orientation (CW or CCW) to ensure air is pulled through the coil correctly.

Can I use this as a universal 24-inch fan blade replacement?
While the 24" diameter is standard, you must verify the bore size (typically 1/2" or 5/8") and the 20-degree pitch to ensure it matches your motor's torque profile.

How does the 4-blade design affect performance?
The 4-blade configuration is specifically calibrated for the static pressure of Marvair condensers, providing the necessary CFM for heat exchange while managing operational noise.
