I would recommend checking with the manufacturer or a qualified HVAC professional to ensure compatibility before making a replacement. They can provide the most accurate information based on the specific model and setup of your system. The pitch of the fan blade, which in this case is 27 degrees for the Lennox 100060-08 18'' 4 Blade Axial Fan, plays a crucial role in the amount of air the fan can move. A fan with a different pitch, such as 30 degrees, may have different airflow characteristics. Therefore, replacing a 30-degree pitch fan with a 27-degree pitch fan may not provide the same performance. Additionally, the 1/2'' bore and CCW rotation are specific to this model and are critical for proper fit and function.
