Modine 5H0578450004 Fan Blade
The Modine 5H0578450004 Fan Blade is a precision-engineered OEM replacement part designed for high-performance service in Modine unit heaters and HVAC systems. This 14-inch diameter fan blade features a 3-blade configuration with a 25-degree pitch, optimized for maximum CFM delivery and static pressure efficiency. Built for durability in demanding commercial and industrial environments, it utilizes a 1/2 inch bore and is designed for Clockwise (CW) rotation. When field-servicing Modine equipment, using this genuine component ensures exact balance and prevents premature motor bearing wear caused by aftermarket vibration. It is a direct drop-in for units requiring consistent airflow performance and quiet operation in residential or light commercial heating applications.
Technical Specifications
- Part Number: 5H0578450004
- Diameter: 14 Inches
- Pitch: 25 Degrees
- Rotation: Clockwise (CW) Facing Discharge
- Bore Size: 1/2" Hub
- Blade Count: 3
- Material: Heavy-gauge aluminum/steel construction
Key Benefits for Contractors
- Exact OEM Fit: Eliminates the need for shaft modifications or hub adjustments during installation.
- Optimized Airflow: The specific 25-degree pitch is calibrated to maintain the designed temperature rise across the heat exchanger.
- System Longevity: Factory-balanced blades reduce mechanical stress on the fan motor, extending the service life of the drive assembly.
- Direct Compatibility: Engineered specifically for Modine HVAC equipment, ensuring safety and compliance with original equipment listing.
Common Questions
How do I determine the rotation for this fan blade?
This blade is a CW (Clockwise) rotation part. Rotation is determined by looking at the discharge side of the fan. Always verify the rotation of the existing motor before installation.
Will this blade fit an aftermarket motor with a 5/8" shaft?
No, this specific part is designed with a 1/2" bore. Attempting to bore out the hub will compromise the balance and integrity of the fan assembly. Ensure your motor shaft matches the 1/2" specification.
Can I use a 4-blade alternative instead of this 3-blade design?
It is not recommended. Changing the blade count or pitch alters the amperage draw of the motor. This Modine OEM fan blade is specified to keep the motor within its rated nameplate service factor.
