This device uses high-pressure nitrogen as a power source. Driven by it, the foam mixture in the liquid storage tank is sprayed onto the surface of the burning material through the foam-water dual-purpose cannon, quickly cooled and produces a flame-retardant and air-isolating film, thereby achieving the purpose of rapid fire extinguishing.
The device can reach the fire scene quickly under the traction of a power vehicle (truck, bus, rickshaw, etc.) and can accurately aim at the target within a range of 25m.
The device consists of a trailer, a liquid storage tank, a foam-water dual-purpose cannon and a nitrogen storage and output device.
