Broan-NuTone 509 Through-the-Wall Ventilation Fan, White Cover — 200 CFM, 8-Inch Duct, 8.5 Sones

Efficient, versatile ventilation for busy spaces

Meet the Broan-NuTone 509 Through-the-Wall Ventilation Fan, designed to move heat, humidity, and unwanted smells from rooms up to 195 sq ft. With a robust 200 CFM airflow, it helps create a more comfortable environment in spaces like one-car garages, kitchens, laundry rooms, or rec rooms. The 8-inch duct and compact housing fit standard wall openings, while the 8.5 sones rating balances effective ventilation with a reasonably quiet operation for a practical, all-day-use solution.

The unit features a durable galvanized steel housing and a built-in exterior wall cap/vent, which reduces installation time and eliminates the need for additional duct work. The motor assembly installs quickly with a twist-lock design, making it easier to secure the fan in place without complex routing. This model also supports customization with Broan-NuTone wall controls (sold separately) for automatic operation based on humidity or motion, and can be paired with a delay-off or countdown timer to automatically turn off after you leave the space.
