摘要 |
The invention relates to a fire extinguishing device (1) of the kind which comprises at least one liquid conduit connected at one end to a source with a fire extinguishing liquid under pressure, and at the other end with channels (40, 23) in a nozzle head (21) with a number of nozzles (24, 27). The channels of the nozzle head comprise a first channel (40) connected to at least one atomising nozzle (27) for discharging liquid in atomised form, and a second channel (23) which has an air intake (25) and downstrean of this is connected to a foam nozzle (24) for discharging a liquid in foamed form. The device can be utilised 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 atomised to a very high fineness by means of a relatively slight pressure of about 10 - 25 bar, and a range of over 10 metres is obtained. Far less water is used for extinguishing a fire than when using conventional fire extinguishing equipment.
