Device for removing wet paint overspray

Installation for painting of objects, in particular vehicle bodies, comprising at least one painting booth and at least one device for separating wet paint over-spray from an over-spray particle-containing exhaust air stream, wherein the overspray particles pass into the exhaust air stream in an application area of the painting installation;

• wherein the at least one device for separating wet paint over-spray from the over-spray particle-containing exhaust air stream comprises at least one separation device for separating the over-spray from at least a part of the exhaust air stream, which has at least one filter element,
• wherein the at least one filter element has a barrier layer including a pre-coat material deposited on a porous filter surface, which prevents agglutination of the filter surface, wherein the at least one filter element comprises an interior space into which the exhaust air stream passes through the filter surface,
• wherein the at least one device for separating wet paint over-spray from the over-spray particle-containing exhaust air stream is configured to cleanse the pre-coat material and wet paint over-spray deposited on the filter surface off the filter surface by compressed air pulses passing from the interior space of the at least one filter element through the filter surface,
• wherein the flow path of the exhaust air stream from the application area to the separation device has at least one narrowed area located upstream of the at least one filter element, and
• wherein the at least one device for separating wet paint over-spray from the exhaust air stream comprises flow guidance elements, which are arranged at an angle of inclination against the horizontal, wherein upper sides of the flow guidance elements each form a respective flow guidance surface which directs the exhaust air stream to the narrowed area.
