Electroseparator with at least an Approximately Point-Shaped Spray Electrode and Spray Ionisation Source

Electrostatic precipitator (10) through which an air stream to be cleaned of particles, in particular a room air stream to be cleaned, flows, comprising:

• i) an ionizer unit (26) which has one or more ionizer rows arranged within the air flow, each ionizer row having at least one approximately point-shaped spray ionization source (40) subjected to an electrical ionizer potential, at least one of the spray ionization sources (40) being formed essentially from a bundle of electrically conductive fibers, and with
• ii) a collector unit (12) arranged downstream of the ionizer unit for particle separation, with a plurality of substantially parallel arranged, electrically conductive collector and driver plates (14, 16) through which the air flow flows, which are alternately subjected to electrical collector and opposite driver potentials,
• wherein the electrically conductive fibers of the spray ionization source (40) are at least partially provided with a metallic coating.
