The Broan MD10TU 10" Universal Automatic Make-Up Air Damper with Pressure Sensor Kit is designed to provide the best technology to equalize pressure between indoors and outdoors, while providing effective ventilation for a cleaner, healthier home. Eliminate gases, smoke or particulates generated from naturally vented combustion devices like a fireplace or water heater. This is an interlocked, synchronized system that installs easily and requires only low voltage wiring to the sensor. Perfect for new construction or retrofit into an existing home.

10" Universal Automatic Make-Up Air Damper with Pressure Sensor Kit
Interlocked make-up air dampers provide outside air when required to keep the air in the home fresher by allowing the range hood to operate at optimum levels
Balance indoor air pressure by providing interlocked make-up air without requiring a direct wire connection between the range hood and the damper
Instead a sensor is attached to the exhaust duct to detect if the range hood is operating
Slave dampers (MD6S, MD8S or MD10S) are interlocked to the main automatic or universal make-up air damper and open in unison for synchronized operation
Interlocked make-up air damper systems meet IRC Code requirements for make-up air with range hoods over 400 CFM
Interlocked make-up air systems avoid wasted energy associated with barometric solutions
Fresh air wall caps are required for use with Make-Up Air Dampers
