VORRICHTUNG ZUM VERTEILEN VON LUFT ODER LOESCHGASEN

摘要

The invention concerns a device for dispersing air or fire-extinguishing gas in an enclosed space, the device having a pressurized feed channel with at least one large-area output zone covered by a gas-permeable fabric. In order, with a device of the kind, to avoid the gas-permeable fabric bulging outwards under the influence of the overpressure in the feed channel, the invention proposes that the feed channel be a double-walled unit with two sheets (1, 2) of fabric disposed a certain distance apart, the two sheets being connected to each other over the flat zone by a multiplicity of threads (3) positioned a certain distance apart from each other and the two sheets being connected to each other hermetically at the edges.
