Abstract (en)
A fire damper for a ventilation system has expandable sealing means (11, 12) configured to seal the interface between outer edge portions of a damper blade (310) and inner wall portions of a fire damper frame (110). The expandable sealing means (11, 12) extends along the inner frame wall portions, which define an air flow opening of the fire damper, and it is covered by a flexible sealing fabric (13).
