As a light foam fire truck, its core is capable of foam and clean water dual mode fire extinguishing, which can accurately adapt to different types of fires, giving consideration to both professionalism and versatility. Equipped with an efficient foam proportion mixing system, foam liquid can be quickly mixed with water according to the set proportion (usually 3%, 6%) to generate a high expansion ratio foam. Through the roof foam fire monitor and the side foam gun, foam can form a sealing layer on the surface of the burning liquid, isolate oxygen gas, and inhibit re combustion. It is specially designed for gasoline, diesel, chemical solvents and other flammable liquid fires (Class B fires), with fast fire extinguishing speed and stable effect, and is suitable for gas stations, chemical parks, oil depots and other high-risk scenarios. At the same time, the clear water fire extinguishing mode can be switched, relying on the fire pump to pressurize and spray clear water through water guns and cannons to extinguish solid material fires (Class A fires), achieving multi-purpose use of one vehicle and meeting the needs of multi scenario fire disposal.
