ULV Fogging works by compressing disinfectants or pesticides through a specially designed nozzle, producing a very fine cold mist or aerosol. Disinfection of surfaces using a fogger is essential to stop the spread of these infections. ULV Fogging equipment is used predominately for the application of disinfectants, biocides, fungicides and pesticides. The mist that is generated via the Fogger is in the form of Ultra Low Volume (ULV) droplets between 5-50 microns (um) in diameter.
