Abstract

En innretning for å hindre tilbakestrønming i ventilasjonskanaler i ventilasjonssystemer og videre spredning av brann og branngasser gjermom ventilasjonssystemet. Irmretningen omfatter en avstandsanordning (11) som kan monteres i en ventilasjonskanal (13) og dekker dermes gjermomstiønmingsareal, til hvilken avstandsanordning (11) det er festet en rørform (12) som har en lengdeutstiekning i den aktuelle strønmingsretning, og hvilken rørform (12) består av et fleksibelt materiale og er åpen i sin fiie ende (15) og har en lengde som er tilsfrekkelig når den faller sammen i tilfelle av tilbakestrømning til å dekke ventilasjonskanalens (13) tvensnittsareal for tettende anlegg mot avstandsanordningen (11).
