AirSanit Air Treatment and Purification technology is based on a triple germicidal action of different stages of purification of recirculated air from a closed enclosure. It incorporates an exclusive DETOX System, UV-C ultraviolet light and filtration before being expelled outside. The filters incorporated are a G4 pre-filter stage, and a high efficiency HEPA 13 type filter, optionally HEPA 14 type and Active Carbon. This system is also effective in eliminating other pathogens such as bacteria and fungi, as well as reducing odours and pollutants present in buildings, called VOC (Volatile Organic Compounds). UTAPs with AirSanit technology are totally compatible with human presence as they do not produce any type of chemical product that may be harmful to people, such as ozone, chlorine or ions of any kind, which may have long-term negative effects on human health as well as produce significant deterioration on surfaces of the treated enclosures over time. The units supplied will ensure the safety of users and workers by improving air quality.
