Description
Product Overview
The Broan MD10TU motorized universal make‑up air damper is engineered to provide a reliable source of fresh air that balances indoor pressure whenever a range hood is in operation. Constructed with a solid black finish and a durable 10‑inch blade, the damper integrates a high‑efficiency brushless motor that delivers consistent airflow while consuming minimal electricity. Designed for both wall‑mount and ceiling‑mount installations, the unit fits seamlessly into modern kitchen designs and complies with IRC code requirements for make‑up air in range hoods exceeding 400 CFM. The remote‑controlled operation allows homeowners to activate the damper without leaving the cooking area, ensuring a convenient and safe cooking environment. With a compact footprint of 1 inch in each dimension and a lightweight 1‑pound construction, the MD10TU offers easy handling during installation and maintenance. The product’s specifications include a 24‑volt DC power source, a single power level, and a brushless motor that reduces wear and extends service life. All components are built to withstand indoor kitchen conditions, providing durability against heat, moisture, and occasional grease exposure.
The damper housing is fabricated from high‑grade steel that has been powder‑coated to resist corrosion and to maintain its sleek black appearance even in the humid environment of a kitchen. The internal components, including the motor shaft and blade, are machined from stainless steel to prevent warping and to ensure long‑term balance at high speeds.
Operating at just 10 watts, the brushless motor delivers the airflow required for make‑up air without imposing a heavy electrical load on the home’s circuit. This low power consumption translates into lower utility bills and aligns with energy‑saving building standards that many homeowners seek to achieve.
The included infrared remote features a single button that toggles the damper on and off, eliminating the need for complex wiring or additional switches. The remote’s range of up to 30 feet allows the user to control the damper from anywhere in the kitchen, and the battery life extends for up to two years under normal usage.
Meeting the International Residential Code (IRC) for make‑up air, the MD10TU ensures that the ventilation system does not create negative pressure that could draw combustion gases from appliances such as gas stoves. The interlocked design also prevents back‑drafts, protecting indoor air quality and maintaining a safe environment for cooking.
The mounting kit includes pre‑drilled holes and stainless‑steel brackets that accommodate both stud and joist installations, simplifying the process for both professional installers and DIY homeowners. The unit’s lightweight design reduces strain on ceiling joists, and the optional wall‑mount kit provides a discreet profile that can be concealed behind cabinetry.
Usage
This make‑up air damper is ideal for residential kitchens where a powerful range hood creates negative pressure that can draw in unwanted drafts from other parts of the house. By supplying make‑up air directly to the cooking area, the MD10TU helps maintain a comfortable temperature and prevents the infiltration of cold air during winter or hot air during summer. The unit works with select Broan range hoods that feature an interlocked damper system, automatically opening when the hood fan is activated and closing when the fan stops, thereby eliminating the need for manual adjustments. Homeowners can also pair the damper with slave dampers such as the MD6S, MD8S, or MD10S for synchronized operation across multiple ventilation points. The remote control provides a user‑friendly interface, allowing the damper to be turned on or off from a distance, which is especially useful when the kitchen layout makes direct access difficult. Installation can be performed by a qualified electrician or a competent DIY enthusiast, as the unit requires a simple 24‑volt DC wiring connection and can be mounted on either a wall or ceiling surface using the supplied brackets.
During winter months, the make‑up air damper prevents the kitchen from pulling in cold drafts that can lower the overall home temperature, reducing the load on the heating system. In summer, it supplies tempered outdoor air, helping to keep the kitchen cooler and reducing reliance on air‑conditioning units.
When paired with additional exhaust fans or bathroom vent fans, the MD10TU’s interlocked operation ensures that each fan’s activation is balanced by a corresponding make‑up air flow, preventing pressure spikes that could otherwise cause doors to slam or windows to rattle.
The damper requires minimal maintenance; the brushless motor is sealed to keep out dust and grease, and the blade can be cleaned with a soft cloth and mild detergent if buildup occurs. Periodic inspection of the mounting brackets ensures they remain secure over time.
If the damper fails to open, the first step is to verify that the 24‑volt DC power supply is active and that the remote control battery is not depleted. Checking the wiring connections for loose terminals can often resolve the issue without professional service.

FAQ
How does the interlocked damper system work?
The interlocked system connects the main make‑up air damper to any installed slave dampers, causing them to open and close in unison when the range hood fan starts or stops, thereby maintaining balanced indoor pressure.
Can the MD10TU be installed on a ceiling?
Yes, the damper includes mounting brackets suitable for both wall and ceiling installations, allowing flexibility to match the layout of your kitchen ventilation system.
What power source does the damper require?
The unit operates on a 24‑volt DC power source and includes a single power level, making it compatible with most residential ventilation wiring setups.
Is professional installation required?
While professional installation is recommended to ensure compliance with local electrical codes, a qualified DIY homeowner can install the damper by following the provided wiring diagram and mounting instructions.
Does the damper affect the range hood’s performance?
No, the MD10TU is designed to complement the range hood’s airflow by providing make‑up air, which actually enhances the hood’s ability to capture and exhaust cooking fumes efficiently.
Installation Guide
Before beginning installation, gather all required tools including a screwdriver, drill, voltage tester, and the mounting hardware supplied with the damper. Verify that the installation location provides at least 1 inch of clearance on all sides to accommodate the 10‑inch blade and that the surrounding area is free of obstructions such as cabinets or light fixtures.
Safety is paramount; disconnect power at the circuit breaker before handling any wiring. Use a voltage tester to confirm that the 24‑volt DC line is de‑energized. Wear protective gloves and eye protection while drilling into studs or joists to prevent injury from metal shavings.
The damper requires a dedicated 24‑volt DC power source. Connect the red wire to the positive terminal and the black wire to the negative terminal, following the wiring diagram provided in the user manual. Ensure that connections are tightened securely to avoid intermittent operation.
Mount the damper using the stainless‑steel brackets included in the kit. For ceiling installations, locate a joist and drill pilot holes through the pre‑drilled holes in the bracket. Secure the bracket with the supplied screws, then attach the damper unit to the bracket, confirming that the blade rotates freely without obstruction.
After mounting, restore power and test the remote control. Press the button to activate the damper; the blade should begin to rotate smoothly and the unit should emit a low‑hum sound. Verify that the damper opens fully when the range hood fan is turned on and closes when the fan stops, confirming proper interlock operation.
Maintenance & Care
Routine maintenance of the MD10TU is simple and helps extend the life of the brushless motor. Once a year, inspect the blade for dust or grease buildup and clean it with a soft, damp cloth and a mild detergent. Avoid using abrasive cleaners that could scratch the blade surface.
Check the mounting brackets and screws for any signs of loosening, especially after prolonged use or if the unit is installed on a ceiling. Tighten any loose fasteners and ensure the damper remains level. Replace the remote control battery with a fresh AA cell when the indicator light begins to dim, typically after two years of operation.
