Broan-NuTone Damper Actuators & Accessories: Precision Air Control from a Ventilation Leader
Broan-NuTone has spent more than nine decades defining residential ventilation, and their Damper Actuators & Accessories reflect that same engineering discipline. These components are the unsung heroes of a well-balanced home: without a properly functioning damper system, even the most powerful range hood or exhaust fan can create negative pressure, backdrafting, and energy waste. Broan-NuTone engineers damper actuators and accessories specifically to integrate with their broader ventilation ecosystem — so installers and homeowners get cohesive, predictable performance rather than a patchwork of mismatched parts.
LinkLogic® Make-Up Air Technology
One of Broan-NuTone's most notable contributions to the damper category is their LinkLogic® platform. Automatic make-up air dampers built on this technology work with SmartSense® ventilation fans and select Broan® range hoods to actively balance indoor air pressure. Rather than relying on passive barometric solutions that can allow unconditioned outside air to infiltrate the home at unwanted times, the LinkLogic® system uses an interlocked design that opens only when the range hood is operating and closes as soon as it powers off — preventing energy waste and maintaining a comfortable indoor environment.
The system communicates between the damper control and ventilation devices using existing AC wiring, meaning no additional low-voltage wiring runs are needed during installation. For installations requiring higher make-up air volumes, slave dampers (available in 6-inch, 8-inch, and 10-inch sizes) can be ganged together in an interlocked configuration — all opening and closing in unison with the main damper unit.
Universal and Directwire Options
Broan-NuTone offers both Directwire and Universal make-up air damper variants. The Universal models, such as the MD6TU and MD10TU, include a pressure sensor kit that attaches to the exhaust duct to detect range hood operation — eliminating the need for a direct wire connection between the hood and the damper. This makes them compatible with virtually any Broan® range hood and simplifies retrofits in existing homes. Directwire models are purpose-built for new construction or full replacement installations where a direct electrical connection can be made.
Code Compliance and Pressure Relief
Modern residential building codes increasingly require make-up air systems for high-powered range hoods. Broan-NuTone's damper actuator lineup is designed to help installers meet International Residential Code (IRC)-based make-up air requirements straight out of the box. In addition, their Pressure Relief Damper with Wall Cap (model BD6) is specially engineered to handle intake or exhaust air from Broan® Energy Recovery Ventilating products — rounding out the accessory ecosystem for whole-home fresh air systems.
Whether you're installing a new kitchen ventilation system, upgrading an existing setup, or ensuring IRC compliance on a build, Broan-NuTone's damper actuators and accessories deliver the reliability and integration you'd expect from the brand installed in over 110 million homes.
