Abstract
Air duct for air distribution systems, for instance a ventilation duct, which is assembled by a plurality of elongated duct sections (1) of incombustible material. Each duct section includes an elongated duct section (5, 6) with an opening (29) which is oriented parallelly along the longitudinal axis of the duct element, and which has the same length as the duct section, the opening being closable by means of a lid (12), which is sealingly connected to the duct section, and which extends along the entire length of the duct element. The lid (12) is connected to the duct element (5, 6) by means of a movable connection having a joint made from an incombustible or meltable material, which is dimensioned to burst or melt as a result of a fire, so that the lid by its own weight can swing out from the duct section (5, 6) when the joint busts as a result of said fire, so that the duct will open and release the pressure therein.
