The content of combustible contaminants in gases extracted from painting booths is reduced by passing through a device. This device comprises means for establishing, between the electrodes and as a function of the number of electrodes (14), direct or alternating voltages with sufficient peak values to create at least one discharge between the electrodes at the site where their surfaces are closest and to limit the intensity of the discharge current, and means (20-20d) for circulating gas allowing the contaminant-laden gas to be passed through the conduit between the electrodes. <IMAGE>
