FIELD: indoor electrical ionizers.
SUBSTANCE: proposed device has high-voltage dc power supply, atmospheric ion emitting cathode, fan, air duct, and anode. Air duct accommodates fan and atmospheric ion emitting cathode. High-voltage dc power supply is provided with two negative voltage leads and one common positive lead which is insulated from power supply case, placed in grounded shield, and connected to insulated anode. First negative lead placed at high potential is connected to atmospheric ion emitting cathode. Second negative lead placed at lower potential is connected to power supply case, to equipment installed in room, and to air duct, as well as to ground.
EFFECT: enhanced effectiveness of device.
