Effectively destroys bacteria, viruses, yeasts and mold spores in the inlet air. The suctioned-in outside air is guided inside an air conditioning duct module, across UV-C high performance lamps. These low-pressure lamps (UV-C-lamps) emit UV-C radiation of precisely 253,7 nm – a spectral line that reliably works to kill off germs. This means that microorganisms coming in from the outside are removed and, at the same time, the entire ventilation system is kept sterile.
