  • DEVICE FOR REMOVING WET PAINT OVERSPRAY
    Publication number: 20240042475
    Abstract: The invention relates to a device for removing wet paint overspray from an outgoing air flow containing over-spray particles. The device separates wet paint over-spray from an over-spray particle contained in an exhaust air stream. The overspray particles in the exhaust air stream are formed during the painting at an application area of a painting installation. The device comprises of at least one separation apparatus for separating the over-spray from the exhaust air stream. The separation apparatus includes a regeneratable surface filter and the flow path of the exhaust air stream from the application area to a separating device having at least one narrowed area. The central direction of flow of the exhaust air stream remains essentially preserved in passing by the narrowed area.

  • DEVICE FOR REMOVING WET PAINT OVERSPRAY
    Publication number: 20170209891
    Abstract: The invention relates to a device for removing wet paint overspray from an outgoing air flow (120) containing over-spray particles. The device separates wet paint over-spray from an over-spray particle contained in an exhaust air stream (120). The overspray particles in the exhaust air stream (120) are formed during the painting at an application area (108) of a painting installation (100). The device (126) comprises of at least one separation apparatus for separating the over-spray from the exhaust air stream (120). The separation apparatus includes a regeneratable surface filter (146) and the flow path of the exhaust air stream (120) from the application area (108) to a separating device (145) having at least one narrowed area (146). The central direction of flow of the exhaust air stream (120) remains essentially preserved in passing by the narrowed area (140).
