UVH 50E

The UVH 50E odorless photocatalytic sanitizer and air purifier has been specially designed to sanitize and deodorize the air in crowded and heavily used public spaces.
This innovative and compact device can be used in any room (restrooms, bathrooms, offices, guest rooms) where you want to filter out and neutralize microorganisms, unpleasant odors, and odors that are harmful to human health. By removing bacteria and viruses from the air, we also prevent them from spreading through contact by settling on surfaces.

Principle of operation

The R-FILTER UVH 50E air disinfection device effectively neutralizes bacteria and viruses in indoor air and eliminates odors. The air purifier combines the synergistic effects of two technologies.

PCO (Photocatalytic Oxidation):
Indoor air circulated by the built-in fans passes through the device, coming into contact with the photocatalytic plates. The plates are illuminated by UV light, which activates the catalyst plates and creates highly reactive hydroxyl and superoxide ions.

UVGI (Ultraviolet Germicidal Irradiation):
The germicidal or bactericidal lamp used is a special UV-C range light source. Short-wave ultraviolet radiation in the UV reactor chamber of the device destroys the DNA and RNA of microorganisms, killing them.

The following air purification process takes place on the TiO-coated surface2:

The TiO coating2 The material described above is a semiconductor in which electrons (e-) are excited into the conduction band when illuminated by light of a certain wavelength, leaving holes (h+) in their place. Holes have a strong oxidizing effect, while electrons have a strong reducing effect. Highly reactive hydroxyl radicals (·OH) are formed from water in the air’s humidity, while superoxide radicals (·O2-) Reagents are formed from oxygen in the air. Odorous substances in the air are broken down, and microorganisms are destroyed by damaging their DNA structure, leaving behind only carbon dioxide and water, which are expelled along with the purified air. The titanium dioxide coating does not wear out and remains functional indefinitely.
