The main principle behind backdraft dampers is allowing airflow in one direction while restricting it in the other. Back draft dampers are ideal for evacuating odors or providing circulation in a one-way route.
Backdraft Damper Products
There are a few different types of back draft dampers, including:
- Back pressure dampers are used as a safety device in pneumatic conveyance systems. The placement of the damper is typically outside of the process area or building and in front of a dust collector. This style of damper is used to stop back pressure situations, such as explosions, from returning through a ducting system to the building or process area - which will cause extensive damage.
- Gravity type dampers or mechanically actuated type of dampers are used in conjunction with a fan to exhaust air from a given space. When the fan is not in operation, the damper closes and does not allow air to flow back into the space or ductwork.
