Reznor 96384 Fan Blade

The Reznor 96384 Fan Blade is a precision-engineered OEM replacement fan blade designed for high-static pressure applications in industrial heating units. Featuring a 24-inch diameter and a 35-degree pitch, this 4-blade aluminum fan is balanced to ensure optimal CFM output and vibration-free operation. The 1/2-inch bore hub is designed for a secure fit on standard motor shafts, facilitating a clockwise (CW) rotation. This specific geometry is critical for maintaining the thermal efficiency of the heat exchanger by ensuring proper airflow velocity across the secondary tubes. When diagnosing a Reznor heater fan not spinning or addressing abnormal resonance, verifying the axial fan blade pitch and hub integrity is essential. This component is built to withstand the high-cycle demands of commercial environments, ensuring consistent airflow and preventing motor overheating due to improper load matching.

• Precise 35-Degree Pitch: Optimized for maximum air movement and static pressure performance in Reznor unit heaters.
• Durable 4-Blade Construction: Engineered for structural rigidity and balanced airflow to reduce mechanical stress on the motor.
• Direct OEM Fitment: Eliminates the need for field modifications, ensuring Reznor unit heater parts compatibility and fast installation.
• Corrosion-Resistant Materials: Designed to maintain aerodynamic integrity in varying mechanical room environments.

How do I determine the correct rotation for this fan blade?
The Reznor 96384 is a clockwise (CW) rotation blade. Rotation is determined by looking at the discharge side of the fan. Installing a blade with incorrect rotation will significantly reduce airflow and can lead to high-limit trips or motor failure.

What are the symptoms of a failing Reznor fan blade?
Common indicators include excessive vibration, increased decibel levels during operation, or visible stress fractures on the blades. If the hub is slipping on the 1/2-inch shaft, the unit may fail to move enough air to satisfy the pressure switch.

Can I use an aftermarket blade with a different pitch?
It is not recommended. The 35-degree pitch is specifically matched to the motor's horsepower and RPM. Altering the pitch changes the amp draw of the motor, which can lead to premature winding failure or insufficient heat dissipation.
