Galvanized steel Backdraft and Pressure-Relief Dampers

Backdraft and pressure-relief dampers are crucial components in ventilation systems, ensuring airflow is properly managed. These dampers help maintain efficient and safe air movement in various HVAC applications.A backdraft damper, also known as a gravity damper, allows air to flow in one direction while preventing reverse airflow. These dampers are essential for exhaust or intake systems. They can operate using gravity, where the air pressure or velocity opens and closes the damper, or they can be motorized to open and close as needed.When choosing backdraft and pressure-relief dampers, consider the following factors:System velocity and back pressure requirementsMounting direction and airflowInstallation method (inserted into the duct or flange-mounted)Operation type (gravity or motorized)Start-open pressure
