The invention relates to a fire extinguishing device that includes at least one liquid conduit connected at one end to a source with a fire extinguishing liquid under pressure, and at the other end having channels in a nozzle head with a plurality of nozzles. The channels of the nozzle head include a first channel connected to at least one atomizing nozzle for discharging liquid in atomized form, and a second channel which has an air intake. A foam nozzle is connected to the second channel downstream of the air intake for discharging a liquid in foamed form. The device can be utilized for effectively extinguishing class A, B, C, and E fires and can with one single handle be converted to fighting fires with either foam or water. The water can be atomized to a very high fineness by means of a relatively slight pressure of about 10 to 25 bar over a range of more than 10 meters. Far less water is used for extinguishing a fire than when using conventional fire extinguishing equipment. |
