Temperature Control Dampers also expel warm air when needed. Places like the basement, laundry room, and attic can accumulate heat over time. The dampers help expel the excess warm air in the same way it would cold air, as well as excess humidity. They’re also found in places where temperature and humidity must be regulated, such as kitchen range hoods, clothes dryer vents, bathroom exhaust systems, and microwaves.

Regardless of the time of year, dampers help to provide a satisfactory temperature, humidity level, and air quality for the inhabitants of a building.
