This 5-blade fan blade configuration is designed specifically for integration with Berko, Marley, and QMark field units, ensuring your unit heater repair meets exact OEM specifications. Constructed from durable, corrosion-resistant materials, this Marley replacement fan provides balanced, vibration-free operation to prevent premature motor bearing failure. Whether you are performing commercial heater maintenance on an ARWH series unit or optimizing industrial ventilation systems, this blade delivers consistent cubic feet per minute (CFM) output. As a professional-grade OEM fan blade, it simplifies HVAC troubleshooting by eliminating the pitch and bore alignment issues common with generic aftermarket alternatives. For contractors managing air handler unit repair, maintaining the precise airflow optimization of these 5-blade assemblies is vital for system efficiency and preventing high-limit trips in fan-forced heating equipment.

• Precision Balance: Factory-aligned 5-blade design reduces mechanical stress on the motor shaft, extending the life of your HVAC system components.
• OEM Compatibility: Specifically engineered for a drop-in fit for QMark, Berko, and Marley equipment, ensuring hassle-free unit heater repair.
• Enhanced Durability: The black finish and robust material choice provide superior resistance to corrosion in demanding industrial ventilation environments.
• Optimized Airflow: Engineered blade pitch maximizes heat dissipation and operational efficiency during commercial heating maintenance.

Which heater models use the 490030103 fan blade?
This component is a direct replacement for QMark ARWH series (specifically ARWH1802, ARWH4807, and ARWH4808) and compatible Berko and Marley fan-forced heaters. Always verify the part number against your unit's schematics.

How do I know if my fan blade needs replacement?
During HVAC troubleshooting, look for visible cracks, blade deformation, or excessive noise and vibration. An unbalanced or damaged blade can lead to motor burnout and reduced heating capacity.

Is this blade compatible with other 5-blade fan motors?
While designed for Marley Engineered Products, compatibility is strictly dictated by bore size, diameter, and rotation. It is highly recommended to use this OEM fan blade only in specified units to maintain safety and performance standards.
