Reznor 195644 Fan Blade
The Reznor 195644 Fan Blade is a critical OEM replacement component designed for compatibility with specific Reznor unit heaters and air handling systems. Engineered for precision airflow, this 10-inch diameter fan blade features a 17-degree pitch across its 5-blade configuration, ensuring optimal static pressure and heat exchanger efficiency. Built with a 3/8" bore, it facilitates a secure connection to the motor shaft, maintaining balanced rotation to minimize vibration and bearing wear. The CCW rotation (counter-clockwise) is essential for correct directional airflow across the heating elements. For HVAC technicians performing maintenance or emergency repairs, utilizing the exact Reznor replacement part ensures the unit maintains its original airflow specifications and operational safety standards. This aluminum-constructed blade provides long-term resistance to heat stress and corrosion in demanding industrial or commercial heating environments.
Key Technical Benefits
- Precision Pitch: The 17-degree pitch is calibrated for specific Reznor motor RPMs to maximize CFM output.
- OEM Compatibility: Prevents the common balance and resonance issues associated with generic HVAC fan blade replacements.
- Durable Construction: Lightweight 5-blade design reduces startup torque requirements on the fan motor.
- Direct Fit: The 3/8" bore size ensures a tight tolerance fit on the shaft, preventing slipping during high-demand cycles.
Common Questions
How do I verify the rotation for this fan blade?
View the blade from the discharge side (facing the hub). The Reznor 195644 is designed for CCW rotation, which is standard for many overhead unit heater configurations.
Does this include the set screw for the motor shaft?
Most OEM blades include the integrated hub and set screw for securing the 3/8" bore to the motor shaft for immediate installation.
What happens if I use a blade with a different pitch?
Using a blade with a different pitch will alter the motor's amp draw and total airflow, potentially leading to motor failure or tripping the high-limit switch on the heat exchanger.
