A system for coating objects having: a) a coating booth in which the objects may be acted upon by coating material and through which an air stream can be guided which takes up overspray particles of the coating material and conveys them away; b) an electrostatically operating separating device working in a dry way whereof a housing has an inlet opening for overspray-particle-laden air and an outlet opening for the cleaned air, wherein at least one separating electrode (25, 40), which has a separating surface, and at least one counter electrode device are arranged in the housing; c) a high voltage source, whereof the poles can be connected to the separating electrode (25, 40) and the counter electrode device respectively; d) an air path (9, 12) for the overspray-particle-laden air, which leads from the base of the coating booth to the inlet opening of the separating device; characterized in that e) the air path (9, 12) leads from the base of the coating booth first to at least two baffles (10, 11) and is there delimited by these, which taper in the manner of a funnel in the direction of flow of the air; wherein the baffles (10, 11) can be uniformly overflown by a more or less continuous film of a separating fluid in which a major part of the overspray particles is taken up and conveyed away; f) the air path (9, 12) leads from the baffles (10, 11) further to the inlet opening of the electrostatic separating device; g) the inlet opening is arranged on the underside and the outlet opening on the upper side of the separating device, such that the air flows through the separating device from bottom to top; h) the at least one counter electrode device is designed such that the air streaming into the separating device and the overspray particles taken away by it are ionized; wherein i) the at least one counter electrode device comprises a corona region which serves primarily for the ionisation and a field region which serves primarily for the separation, wherein the corona region is arranged below the field region. a) a coating booth in which the objects may be acted upon by coating material and through which an air stream can be guided which takes up overspray particles of the coating material and conveys them away; b) an electrostatically operating separating device working in a dry way whereof a housing has an inlet opening for overspray-particle-laden air and an outlet opening for the cleaned air, wherein at least one separating electrode (25, 40), which has a separating surface, and at least one counter electrode device are arranged in the housing; c) a high voltage source, whereof the poles can be connected to the separating electrode (25, 40) and the counter electrode device respectively; d) an air path (9, 12) for the overspray-particle-laden air, which leads from the base of the coating booth to the inlet opening of the separating device; characterized in that e) the air path (9, 12) leads from the base of the coating booth first to at least two baffles (10, 11) and is there delimited by these, which taper in the manner of a funnel in the direction of flow of the air; wherein the baffles (10, 11) can be uniformly overflown by a more or less continuous film of a separating fluid in which a major part of the overspray particles is taken up and conveyed away; f) the air path (9, 12) leads from the baffles (10, 11) further to the inlet opening of the electrostatic separating device; g) the inlet opening is arranged on the underside and the outlet opening on the upper side of the separating device, such that the air flows through the separating device from bottom to top; h) the at least one counter electrode device is designed such that the air streaming into the separating device and the overspray particles taken away by it are ionized; wherein i) the at least one counter electrode device comprises a corona region which serves primarily for the ionisation and a field region which serves primarily for the separation, wherein the corona region is arranged below the field region.
