Fog cannon machine, as a new type of dust removal equipment, its working principle contains high-tech wisdom. It is pressurized by a special high-pressure pump and sprayed out through the nozzle. The unique design at the nozzle breaks the water into tiny droplets, which are usually in the micrometer range. These micron-sized droplets have a large surface area and are able to make full contact with dust particles in the air. Just like a tiny "dust fairy", when the fog drops and dust meet, the dust particles will be absorbed by the fog drops and settle together under the action of gravity, so as to achieve the purpose of reducing the dust concentration in the air.
