The device is composed of a circuit part (1) and an ionisation part (2). In the circuit part (1), the voltage of up to three kilovolts necessary for forming coronary discharges is generated. The ionisation part (2) is composed of electrodes (14, 15) which are arranged on the two sides of an insulator plate (16). During operation, an electron emission occurs at the second electrode (15) and generates negative oxygen ions by means of which bacteria and spores are killed and odours removed from the air. …<IMAGE>… |
