The fog cannon is a highly efficient dust suppression and environmental protection device, widely used in dust-intensive places such as construction sites, mines, coal yards, steel plants, and cement plants. It atomizes water into micron-sized fine particles through a high-pressure water pump, which are then transported over long distances by an axial flow fan. The particles capture dust in the air, increase their weight, and settle, achieving rapid dust reduction and air purification. The whole machine consists of a water tank, high-pressure water pump, nozzles, fan, rotation and tilting device, electrical control box, and remote control. It supports fixed installation and can also be equipped with a mobile chassis or vehicle mount. It is suitable for dust removal, dust suppression, and cooling operations in urban demolition, metallurgy, coal chemical industry, thermal power generation, and open-air material storage yards.
