QWLB15 two-phase water mist fire extinguishing gun, with its unique technology and safe, reliable and convenient

operation, has achieved the efficiency of 1/3 of the energy saving and consumption of similar fire-fighting

equipment.With low working pressure,compact structure, lightweight knapsack, the water mist fire gun is convenient

in the smoke, gas, steam, oxygen and other bad environment to achieve the purpose of fire extinguishing,it is more

combat effectiveness of a new generation of extinguishing equipment.

Water spray gun using air pressure water and formation water mixed with a certain pressure of fire fighting medium,

achieve the purpose of extinguishing a fire, it is equipped with SCBA to protect rescuers from being affected by the

rescue environment, applicable to save urban residential, tunnels, bazaar, highway, high-rise residential, automobile,

etc.

The gun allows the water to rapidly form a fire extinguishing mist with a diameter of 7 to 100 microns, covering the

upper and surrounding flames to isolate the air and absorbing the heat.According to the type of fire, the spray gun

can be selected accurately.

Extinguishing equipment:

1. Check whether the cylinder is under rated pressure.

2. Check whether the water is full.

3. Place the gas bottle and water tank on the back strap and tighten the band.

4. Wear the equipment (the cylinder control valve is down), put the shoulder belt and belt in the right position,

insert the belt buckle and tighten the belt.

5. Open the cylinder and water tank valve when arriving at the designated fire field.

6. Turn on the water spray gun to adjust the handle (safety lock).

After completing the above operation, the water mist fire extinguishing gun can be used to extinguish the fire

(by adjusting the switch on the fire extinguishing gun to transform the injection mode). 

1, This manual provides the user with the use and maintenance of the standard process, users must be familiar with

the training & guidance, maintenance and replacement of two phase flow knapsack water mist fire extinguishing

installation method of some parts, provided by this manual before using.

2. The pressure reducing valve of this product is set up when it leaves the factory, and the user cannot adjust

himself.

3. Improper use of this extinguishing device will make the user to be in a dangerous environment, causing

casualties.

4. This product should be handled gently to avoid impact.
