Backdraft dampers (also called gravity dampers) allow airflow in one direction and prevent reverse airflow for use in exhaust or intake HVAC systems.
May 27, 2021 · This guide will bring you up to speed with everything you need to know about backdraft dampers—what they are, how they work, how to choose and use them, where to place them, and most importantly, why you should care. Backdraft dampers are one of many kinds of dampers that can be installed in HVAC and exhaust systems.
May 25, 2021 · Backdraft dampers, also known as gravity dampers, are used in ventilation systems to allow airflow in one direction and prevent airflow in the opposite direction. A relief damper has an elevated and adjustable start-open pressure while providing the backdraft function - think of it as controlled leakage in the direction of flow.
A backdraft damper is able to allow contaminated air to flow out of the home but prevents contaminated air from sweeping back in to the home. Without a backdraft damper in place, horrid odors that sometime infiltrate a certain room in the home would not have a way of dissipating.
The BDD5 is suitable with 5'' duct. Neoprene damper seal minimizes leakage. Requires from 0,04 to 0,08 inches wg pressure to open. Simple inistallation in any position - entire assambly inserts into duct.
FAMCO’s backdraft dampers have a 2-blade assembly and a foam seal that keeps air from coming back in, and are typically used for heat exchangers, exhaust systems, solar heating systems, and other intake or or exhaust applications where a powered damper is not needed.
Mar 19, 2024 · Industrially, backdraft dampers prevent system backflow of harmful fumes or chemicals, lowering the re-entry of dangerous exhaust. Read on to understand more about backdraft dampers and how to use them in both residential and commercial settings.
Apr 30, 2024 · Backdraft dampers help control airflow in your kitchen. They open when needed, allowing smoke and fumes to escape, and close when the range hood is off (preventing outside air, bugs, and debris from coming in). This mechanism aids in maintaining a comfortable kitchen environment.
Backdraft dampers are a specialized type of damper designed to prevent air from flowing the wrong way in an air duct. Often thought of as check valves for ductwork, backdraft dampers keep air flowing as it should.
Discover a range of high-quality dampers designed for commercial, and industrial applications, where precision and reliability are paramount. Our Backdraft Dampers are engineered to facilitate unidirectional airflow, preventing the backflow of air into spaces where it is not desired.
