A high voltage is applied to one of the frequencies in the specified range. In this case, a barrier electrical discharge arises between the crossed electrodes, crossing all the interelectrode space. Thus, in the cross section of the ventilation duct, perpendicular to the direction of the gas flow, there are created "iH)" i.e., centers formed by a low-temperature gas discharge plasma.

A gas stream containing toxic venous gases, passing through the discharge zone, is exposed to "active white centers generated in the discharge (ultraviolet radiation, atomic oxygen, active nitrogen, electrons, etc.) and decomposes (oxidizes) to harmless for the environment chemical compounds. - water and carbon dioxide.
