Reznor 195683 Fan Blade

The Reznor 195683 Fan Blade is a critical OEM replacement component engineered specifically for high-capacity UDAP-300 and UDAS-300 unit heaters. As a veteran-grade part, this 24-inch, 3-wing assembly is factory-balanced to eliminate shaft vibration and protect the motor bearings from premature fatigue. Designed with a precise 20-degree pitch, the Reznor 195683 optimizes static pressure and CFM delivery, ensuring the heat exchanger remains within its designed temperature rise parameters.

When performing a Reznor fan blade replacement, using this genuine 195683 assembly ensures exact hub-to-shaft alignment, which is vital for maintaining the aerodynamic efficiency of industrial heating systems. This blade is constructed from heavy-gauge alloys capable of withstanding the high-velocity air cycles typical of 300,000 BTU gas-fired units. For contractors maintaining UDAP-300 unit heaters, inventorying the 195683 fan blade is standard practice to prevent downtime when a hub failure or blade deformation occurs. Using original Reznor HVAC parts ensures that the system maintains its original engineering specifications for safety and airflow performance.

• Precision Balanced: Factory-aligned 3-wing design reduces mechanical stress on the blower motor and prevents cabinet rattling.
• Optimized Airflow: The 20-degree blade pitch is engineered for the 300-size chassis to maximize heat distribution.
• Exact Compatibility: A direct-fit OEM part for Reznor UDAP-300 and UDAS-300 series, eliminating the need for field modifications.
• Industrial Durability: Rugged construction stands up to the thermal cycling and humidity found in commercial warehouse environments.

Does this fan blade include the mounting set screw?
Yes, the hub typically includes the necessary hardware to secure it to the 1/2-inch motor shaft, though reusing the existing shaft keys is recommended where applicable.

Can I use this on a smaller UDAP unit, like a UDAP-100?
No. The Reznor 195683 is a 24-inch blade specifically tailored for the 300,000 BTU models. Installing this on a smaller motor will lead to amperage draw issues and eventual motor burnout.

How can I tell if my current fan blade needs replacement?
Check for hairline fractures at the hub where the blades are riveted or welded. Any visible wobble during the spin-down cycle indicates a loss of balance that requires immediate replacement to protect the motor.
