Reznor 17909 Fan Blade 326070-701 it provides precise downstream pressureThe Reznor 17909 Fan Blade is a direct replacement component engineered specifically for Reznor F and B series unit heaters. This 16 inch, 4 blade aluminum fan assembly is designed with a 23 degree pitch and a 1 2 inch bore for precise fitment on Model F165 and Model F200 gas fired equipment. To maintain optimal airflow and static pressure, the blades are precision balanced to minimize vibration and prevent premature motor bearing fatigue. When
