Reznor 195648 Fan Blade

The Reznor 195648 Fan Blade is a critical 16-inch HVAC replacement part engineered for high-efficiency air movement in industrial unit heaters. Designed specifically for the UDAS-100 and UDP-100 gas-fired models, this 3-blade fan propeller ensures optimal heat exchanger cooling and consistent discharge temperatures. A failing or unbalanced blade can lead to excessive vibration, motor bearing fatigue, and limit switch tripping due to reduced CFM. Replacing a damaged blade with this OEM Reznor part restores the precise airflow patterns required for peak combustion performance and system longevity.

Constructed with a 1/2-inch bore and CCW (Counter-Clockwise) rotation, this blade mounts securely to the motor shaft. Technicians should verify the hub position—typically set at 2 and 1/8 inches from the motor face—to ensure the blades are properly centered within the orifice for maximum static pressure. This heavy-duty fan blade is built to withstand the thermal stresses of commercial heating environments, providing a reliable solution for restoring unit heater airflow and HVAC system efficiency.

• Precision Airflow: The 16-inch diameter and 3-blade geometry are factory-calibrated to maintain the required CFM across the heat exchanger, preventing high-limit trips.
• OEM Compatibility: Exact replacement for Reznor 195648, ensuring a perfect fit for 1/2-inch motor shafts without the need for bore adapters.
• Vibration Reduction: Factory-balanced design minimizes mechanical noise and extends the service life of the condenser fan motor bearings.
• Durable Construction: Engineered to hold its pitch and structural integrity under high-demand gas-fired heater cycles.

• How do I confirm the rotation of my existing blade? Rotation is determined by looking at the blade from the discharge side. This CCW rotation fan blade moves air away from the motor when rotating counter-clockwise.
• What causes a fan blade to slide on the motor shaft? Thermal expansion or a loose set screw can cause the blade to shift. Always check the shaft for scoring and ensure the set screw is tightened onto the flat of the 1/2" bore shaft.
• Will this fan blade fit other unit heater brands? While designed for Reznor UDAS and UDAP series, it may fit other brands if the diameter, 3-blade count, 1/2" bore, and CCW rotation specifications match exactly.
