Broan-NuTone 509S Through-the-Wall Ventilation Fan — 200 CFM, 8-inch Duct, White Cover

Smart ventilation where you live and work

The Broan-NuTone 509S Through-the-Wall Ventilation Fan is designed to move air where it matters—garages, kitchens, laundry rooms, rec rooms, and more. With up to 200 CFM, it helps reduce heat, humidity, and lingering odors in spaces up to 195 square feet, creating a more comfortable environment without requiring a full duct system.

Fast, tool-free installation

This unit features a built-in exterior wall cap/vent that can simplify setup by reducing the need for external ducting. The on/off switch is integrated into the cover, so you can operate the fan with a simple toggle and avoid wiring a separate wall switch. A compact 8 inch duct and a twist-lock motor assembly support a quick, straightforward install.

• In-wall installation with no ductwork in many configurations
• Exterior wall cap reduces install time and protects against elements
• Integrated on/off switch for immediate, convenient control

Reliable performance and durable construction

The galvanized steel housing resists wear and the elements, while the built-in damper helps minimize backdrafts. A bird screen helps keep leaves and debris out of the moving parts, supporting long-term operation in varied spaces.

• 200 CFM capacity for steady air exchange
• 8" duct; housing fits walls 4.5 to 9.5 inches thick
• Durable galvanized steel with built-in damper and bird screen

Real-world use scenarios to consider

Picture a garage after a long project: air is refreshed as warm air and odors escape through the outlet. In a laundry or kitchen space, the fan can help curb humidity and maintain comfort during peak activity. The compact, all-in-one design is built to integrate into existing walls with minimal fuss.

Note that while performance can improve air movement in suitable spaces, results depend on room size and installation specifics. This unit offers a practical option for homeowners seeking better ventilation without complex ductwork or extensive remodeling.
