Replacement Fan Blade
The Broan-NuTone S99020165 is a 7.5 in diameter replacement blade designed for bathroom exhaust fans. It fits a 3/16 in shaft and has a 1 1/4 in width. The blade is sold new as an HVAC control accessory.
Restoring Airflow Performance
This blade replaces a worn or damaged original to restore proper ventilation. The jump is worth it when the existing fan motor runs but airflow has dropped due to blade damage or deformation. A new blade returns the system to its intended air-moving capacity.
Homeowners Maintaining Existing Fans
This part suits owners of compatible Broan-NuTone bathroom fans needing a direct replacement blade. It is not for buyers who want more airflow than the original design provides or for builders who need a complete fan assembly with motor and housing.

Questions about this item
What shaft diameter does the 7.5 in fan blade require?
The blade is designed for a 3/16 in motor shaft, so the fan housing must accommodate that exact shaft size for a secure fit.
How is the blade secured to the motor shaft during installation?
Slide the blade onto the 3/16 in shaft and tighten the set screw against the flat side of the shaft; skipping the flat alignment causes wobble.
When should the 7.5 in blade be replaced?
Replace the blade if the plastic shows cracks, warping, or if vibration increases after cleaning, as damaged blades reduce airflow and strain the motor.
