Indoor air quality has a noticeable impact on human health and comfort. This device can be used wherever harmful viruses and bacteria and unpleasant odors are to be eliminated.

Especially developed for disinfection and deodorization of heavily used public areas such as offices, doctors' waiting rooms, grocery / retail outlets, restaurants, hotels, laboratories and toilets.

There is a synergistic effect of UVGI (Ultraviolet Germicidal Irradiation) and PCO (PhotoCatalytic Irridation) used in the device. You decide whether you want to take advantage of odor removal or disinfection, or both to achieve your air purification goals. Photocatalysis takes place under normal temperature and humidity conditions, no special operating conditions are required. The device can be wall mounted.

Functional Principle

It is well known that surfaces coated with nano-TiO2 show self-cleaning activities under the influence of sunlight.

Titanium dioxide coated surfaces are used also as a photocatalyst in our wall mounted model, but they are illuminated with ultraviolet light here.
The fans in the device to circulate the air in the room, to be disinfected and deodorized. The air is first exposed to a disinfecting ultraviolet light, then flows touching the UV light-activated photocatalyst.


On the surface coated with TiO2 the following air purification process takes place:

UVE 220 - Advantages of use
  • Synergistic effect of UVGI and PCO

  • Improves indoor air quality

  • Kills bacteria and viruses

  • Odor control

  • There is no filter in the device

  • Works without chemicals

  • Environmentally friendly

  • Low energy cost, programmable cycle

  • Made of stainless steel, no risk of corrosion

  • Minimal maintenance effort

  • Easy installation

  • Can be wall mounted


The above coating is a semiconductor and when light of a certain wavelength strikes the surface of the titanium dioxide, electrons (e–) are transferred from the valence band to the conduction band.

At the same time, electron holes (h+) are formed in the valence band. The holes oxidize strongly, while the electrons have a strong reducing effect.


From the water arise highly reactive hydroxyl radicals (·OH) and from the atmospheric oxygen reactive superoxide radicals (·O₂ˉ).

As a result, all the pollutants are quickly decomposed. The ultraviolet rays change the DNA structure of micro organisms and cause their destruction. Microbes and organics will be mineralized to water and carbon dioxide.
