Modine 5H0635550004 Fan Blade

The Modine 5H0635550004 Fan Blade is a critical direct replacement 4-blade fan engineered for specific Modine unit heaters, including the PA105, HE200, and HE250 series. This heavy-duty assembly serves as the drop-in successor to the discontinued Modine 5H63555-4, ensuring seamless mechanical compatibility without the need for field modifications. Designed for industrial-grade air movement, this precision-pitched blade assembly maintains the specific cubic feet per minute (CFM) requirements of your HVAC equipment, preventing motor overheating and ensuring consistent heat exchanger discharge temperatures.

As an authentic HVAC replacement part, this 2.66 lb component is balanced for high-RPM operation, minimizing vibration and reducing bearing wear on the blower motor. When performing a swap-out, technicians should verify the hub bore and set-screw alignment to ensure a secure fit on the motor shaft. Replacing a warped or corroded blade with this genuine OEM Modine fan blade restores the peak aerodynamic efficiency of your unit heater fan, extending the service life of the entire system in demanding commercial environments.

Key Benefits

• Optimized 4-blade design engineered specifically for PA105 and HE-series unit heaters to maintain rated airflow.
• Industrial-grade construction prevents blade flex and maintains pitch accuracy under high thermal loads.
• Precision balancing reduces acoustic signature and mechanical stress on the fan motor assembly.
• Streamlined installation as an OEM component, fitting standard Modine motor shaft configurations.

Common Questions

Is the Modine 5H0635550004 compatible with my PA105 unit?
Yes, this fan blade is the designated replacement part for the PA105, as well as the HE200 and HE250 model series heaters.

What is the difference between 5H0635550004 and the older 5H63555-4?
The 5H0635550004 is the current manufacturing standard and direct substitute for the 5H63555-4; they are functionally and dimensionally identical.

Can I use this on a non-Modine unit if the diameter is the same?
It is not recommended. Pitch, rotation, and hub depth are calibrated precisely for Modine’s heat exchanger airflow resistance to prevent motor burnout.
