ULV Fogging

ULV/Fogging machines allows the disinfectant to be passed through the unit, which generates an airborne mist of micro-droplets. These droplets diffuse through the treated area and settle out onto surfaces, meaning that the material used will be active both as a space spray and a surface spray.

The key to successful use of ULV is the production of an optimum size of spray droplet. It must be small enough to remain airborne without being too small to hit surfaces – research has shown the optimum droplet size to be around 15 microns. These droplets are small enough to be carried on air currents into small cracks and crevices that are hard to reach using conventional cleaning and spraying, yet still heavy enough to settle out within an hour, so that treated areas can be re-entered with the minimum of delay.
