Overpressure damper

The GP100K overpressure dampers are used to naturally intake or exhaust air by using just the pressure difference between the two sides.

In-duct overpressure damper – Model GP 100 K
The blades move freely to allow air to pass through until the pressure between the two sides of the grille equalises.
At this point, the blades close automatically through gravity.
