What Is a Backdraft Damper?
A backdraft damper, also known as a gravity damper, is a piece of equipment that allows air to flow through in one direction while preventing air from entering the opposite side, also known as a backdraft. Backdraft dampers assist in the exhaust or intake of heating, ventilation, and air conditioning (HVAC) systems.
Why Do I Need a Backdraft Damper?
A backdraft damper is beneficial if you are looking to control and enhance the air quality of your home or office. Installing a damper keeps temperature-controlled or purified air within your space while simultaneously keeping outside air from coming in. A backdraft damper is useful in controlling temperature but can also be used to improve the ventilation of a space.
Ideal for all tumble dryer vent pipes / hoses, bathroom extractors and vents, air conditioning and heating units, kitchen vents and fans, all home wall and ceiling vents, heat transfer and ventilation systems, gas and electric dryers, cooker hood extractors, as well as a wide variety of industrial uses.
