The Ultravation UVMatrix AS-R Series is capable of exposing airborne microorganisms circulating through an HVAC system to high levels of UV-C energy. A major benefit of HVAC airstream disinfection is the reduction of airborne bacteria and viruses that accumulate in one area, room or office from being spread to others. Another is the ability to apply a very intense germicidal dose with needed exposure or dwell time since the ductwork lends itself to that purpose and people are completely shielded from the germicidal UV light.
