Broan-NuTone RE70BN 70 CFM Bath Fan Replacement Motor Kit – Easy DIY Upgrade

Upgrade the air quality in your bathroom with the Broan-NuTone RE70BN Replacement Motor Kit. This direct replacement is designed for select Broan-NuTone 70 CFM exhaust fans and can deliver up to 40% more power on certain 50 CFM models, helping air move faster and moisture evaporate more quickly after steamy showers. While it won't claim specific results for every install, users often notice a more confident airflow and a quicker feel of freshness after ventilation begins.

Engineered for everyday life, the kit operates at 6.0 sones, balancing effective ventilation with a tolerable noise level that many households find acceptable for routine bathroom use. The motor is built to fit common housing sizes and includes a blower wheel that works in harmony with the rest of the fan, ensuring reliable operation over time. The result can be a more consistent removal of odors and moisture, contributing to a bathroom environment that feels cleaner and more comfortable.

What makes this upgrade particularly appealing is the DIY-friendly installation. No wiring is required, and there is no drywall cutting or messy renovations. In roughly 10 minutes or less, you can swap your old motor for a fresh, high-quality replacement. The kit includes genuine Broan-NuTone parts—a motor, a blower wheel, two motor mounting plates, and the necessary installation hardware—so you have everything you need in one package.
