Function and effect
During idle state the blades are closed. They only open when an excess pressure is present (adjustable with counterweights). Therefore the excess pressure damper can also be used as a pressure compensation opening between two rooms. A direct connection to an air duct system is not necessary. The blades protrude the frame by 18 mm when fully opened.
