Modine 5H0738370004 Fan Blade

The Modine 5H0738370004 Fan Blade is a critical OEM replacement part designed for high-static pressure applications in Modine unit heaters, specifically the PD150 and PDP150 series. This industrial HVAC fan blade features a 15.5-inch diameter with a 26-degree pitch, precision-engineered to maintain optimal CFM output and heat exchanger efficiency. Built as a 3-blade blower component with a 1/2-inch bore, it is designed for clockwise (CW) rotation. This part is the direct technical successor to the legacy 5H73837-4 model, ensuring a drop-in fit without the need for motor shaft modifications. For contractors performing commercial heater repair, this heavy-duty aluminum blade provides the aerodynamic balance required to minimize vibration and extend the service life of the fan motor. Whether you are conducting seasonal maintenance or an emergency swap, using this genuine Modine hub-and-blade assembly ensures your equipment operates within original factory specifications for airflow and safety.

• Direct Compatibility: Engineered as the exact replacement for 5H73837-4 to ensure seamless installation on 1/2-inch motor shafts.
• Optimized Airflow: The 26-degree pitch is specifically calibrated for Modine PD150 unit heaters to maximize thermal transfer.
• Durable Construction: High-grade materials resist fatigue and corrosion in demanding industrial heating environments.
• Precision Balance: Factory-set blade alignment reduces mechanical stress on the motor bearings and lowers operational noise.

What Modine models use the 5H0738370004 fan blade?
This blade is primarily utilized in 150,000 BTU units, including the Model PD150 and PDP150 power-vented gas-fired unit heaters.

How do I verify the rotation direction before installing?
This is a Clockwise (CW) rotation blade. Rotation is determined by looking at the discharge side (facing the air stream) or following the manufacturer's directional arrow stamped on the hub.

Can I use this to replace a 12-degree pitch blade?
No. While some 15.5-inch blades exist with different pitches, using a 26-degree blade where a 12-degree was specified will overload the motor and potentially lead to component failure. Always match the pitch and diameter exactly.
