Foggers are capable of atomizing light liquids; both water and oil-based, including pesticides, deodorants, disinfectants and, of course, water. Heavier liquids can also be fogged, providing their viscosity and surface tension is not too great. (Viscosity and surface tension affect both output rate and droplet size distribution.) In general, the output of our foggers falls in a range from a near-invisible ULV dry fog (7-10 micron diameter), to an intermediate fog (15-20 microns), to a heavy, wet fog (30+ microns). Droplet size differs with nozzle design, fogger model number, liquid discharge rate and, of course, the liquid being applied.
