The dust suppression truck (also known as a multi-functional dust suppression truck or fog cannon truck) is a core piece of equipment in modern environmental protection and sanitation. It is specially designed to control dust pollution. Through a high-pressure atomization system, it converts water or dust suppressants into micron-level water mist, which adsorbs suspended particles in the air, achieving the triple effects of dust fixation, dust reduction, and air purification. It is widely used in areas with high dust emissions such as urban roads, construction sites, mines, ports, and storage yards, and is an important equipment for controlling atmospheric pollutants such as PM2.5 and PM10.
