FIELD: medical engineering. ^ SUBSTANCE: device has body having inlet and outlet openings, cylindrical housing, air filter, power supply source, power switch-off, element for controlling fan rotation speed, unit for controlling fan rotation speed, ion-producing electrode, excitation circuit, high voltage transformer, rectifier, fan, having electric motor and blades, air ion separator and tube. The cylindrical housing is enclosed in the device body between the inlet and outlet openings. The air filter is fixed in the outlet openings arrangement zone. Fan, ion-producing electrode and air ion separator are enclosed in the housing. The tube connects the air ion separator to internal space of the cylindrical housing at the place the electric motor is located. The air ion separator is manufactured as hollow metal surface having convex perforated side facing the ionizing electrode. ^ EFFECT: increased negative air ions concentration; high quality of air cleaning. ^ 2 dwg |
