About Backdraft Roof Dampers

Backdraft Roof Dampers are designed to prevent the flow of air from outside the building into the interior. They are an important part of a building's ventilation system, as they help maintain a comfortable indoor climate and reduce energy costs.

Types of Backdraft Roof Dampers

Backdraft dampers come in a variety of shapes, sizes, and materials. The type chosen depends on the particular application and whether it is being used for intake or exhaust. Some common types include gravity backdraft dampers, pressure-actuated backdraft dampers, and motorized backdraft dampers.

How Backdraft Roof Dampers are Made

Backdraft roof dampers are typically constructed from galvanized steel, aluminum or stainless steel. The blades may be single-wall or double-wall construction depending on the application requirements. They also feature a spring-loaded closure mechanism which helps to ensure that they close properly when not in use.

Industries that use Backdraft Roof Dampers

Backdraft roof dampers can be found in many industries such as commercial buildings, industrial facilities, HVAC systems, laboratories, hospitals and cleanrooms. Professionals working with these industries often use them to control airflow for safety reasons or to ensure proper ventilation.
