Reznor 195678 Fan Blade

The Reznor 195678 Fan Blade is a critical OEM replacement part engineered for high-performance airflow in industrial and commercial heating applications. Specifically designed for use with Model UDAP 150 and Model UDAS 150 gas-fired unit heaters, this 19-inch diameter fan blade features a robust three-blade configuration to ensure optimal static pressure and air distribution. The counterclockwise (CCW) rotation and precise 1/2-inch bore allow for a direct-fit installation on standard motor shafts, maintaining the original equipment’s efficiency and thermal discharge patterns. Built by Nortek Global HVAC, this heavy-duty component is balanced to prevent vibration-induced mechanical wear on the motor bearings, making it the professional choice for restoring system reliability during seasonal maintenance or emergency repairs. Its corrosion-resistant construction is tailored for the high-demand environments typical of Reznor unit heaters, providing consistent HVAC ventilation performance and reliable heat exchange.

Key Benefits

Common Questions

• How do I confirm the rotation of this blade? This fan blade is designed for CCW rotation (counterclockwise) when viewing from the discharge side (opposite the motor).
• Can this blade be used on 200 or 250-size heaters? No, the 195678 fan blade is specifically sized at 19 inches for 150-size units. Oversizing or undersizing the blade can lead to motor burnout or inadequate heat exchange.
• Is the hub included with the fan blade? Yes, the hub is an integral part of the assembly, featuring a 1/2-inch bore size for standard motor shaft mounting.
