Fireblocking device for preventing transfer of fire through ventilating apertures or similar passages, in openings for thermal fire ventilation, in ventilation ducts, in process plants or in vented facade exteriors, in vented fire blankets, vented fire protective curtains or vented protective screens against explosions. The device includes a combination of a heat absorbing and heat storing body, and an element which includes and/or adsorbs and intumescent material.
Claims9
A ventilation device for passing air therethrough, and including an upstream side and a downstream side, the ventilation device including a passive fireblocking means comprising:
- at least one grille body on the upstream side comprising a plurality of evenly distributed openings permitting air flow therethrough, the grille body being formed of or coated with an intumescent material;
- and
- adjacent to and downstream from the at least one grille body, at least one thermally conductive metal mesh permitting air flow therethrough,
- wherein the metal mesh comprises metal pipes filled with liquids, minerals or mixtures thereof to provide heat storage capacity, and
- wherein the intumescent material swells when exposed to sufficient heat to close the evenly distributed openings, and the metal mesh has a capacity for heat storage.
