Abstract

The invention relates to a device for purifying a gaseous medium, said device comprising a reactor (9), at least one element (5) consisting of a tangential ventilator having blades provided with a photocatalytic coating (6) based on titanium oxide, for example, and associated irradiation means (7). The invention also relates to a method for purifying gaseous media using said device. The aim of the purification process is to inactivate and/or degrade chemical and/or biological species contained in the gaseous medium to be treated.
