（1）The flow rate is automatically adjusted according to the change of water pressure. The working pressure range is 3.5kg to 16kg, and the maximum flow rate is 600l / min when the working pressure is 8kg. The spray mode is realized by rotating the gun head protective cover Direct water column, flow of flow, flow of mist and high pressure chamber rinse a variety of injection methods, jet water column is to achieve the intensity of enhanced water, is conducive to fire fighting, was mist umbrella shape can absorb heat and adsorption of smoke and dust. Prevent heat radiation and firefighters can send fresh air to protect the personal safety of fire fighters.
（2）Water column range, range and stability. It needs to reduce the working pressure and still maintain a good range stability.
（3）When the recoil force is small, when it is pressurized or depressurized, it has a good delay function to achieve the change of water flow buffer, which has the function of constant pressure, eliminating the reaction force is too large and can act on the human body. Reduce the physical strength of fire fighters.
（4）Nozzle tip mouth with atomized cone to make the spray more detailed heat absorption effect is better.
（5）Water gun made of aluminum. T5 thermal external. Anodized anti-corrosion treatment, durable and long life. Water gun can be equipped with German-style buckle interface, British fast interface, Japanese-style quick interface and other wire connections.
