High precision cutting processing, built-in cylinder control, external air and water sources. It consists of a spray gun body, nozzle, nozzle cap, cleaning needle, locking cap, and other internal components. The internal structure requires high tightness, the nozzle needs to be deburred, and the cleaning needle needs to be durable. By adjusting the gas-liquid flow ratio, mist droplets with different particle sizes ranging from 3 to 100 microns can be sprayed, and the nozzle can run 200 cycles per minute without dripping water. Different particle size choices can achieve dust reduction function.

Adopting a two-stage atomization method, the air-water mixture is sprayed from the central hole to achieve the first atomization; Then mix with the gas coming out from the nearby nozzle to achieve a second atomization. Achieve ultrafine atomization effect, with a minimum particle diameter of up to 5 microns.

The small water droplets generated during atomization collide at high speed, producing a large amount of negative charges that can adsorb fine dust and accelerate its descent; At the same time, the air humidity is increased while spray, so that the dust is not easy to float.
