Abstract

A filter device for separating paint overspray from a raw gas flow containing overspray particles is provided, including at least one filter element, to which at least a part of the raw gas flow is feedable, and a clean gas chamber, to which the raw gas flow filtered by the filter element is feedable as a clean gas flow. In the event of a filter rupture at at least one filter element of the filter device, contamination of the clean gas side of the filter device and regions downstream of the filter device of a painting installation containing the filter device is kept as low as possible through use of at least one safety filter arranged downstream of the at least one filter element and associated with the clean gas chamber such that at least part of the clean gas flow is filterable in the event of a filter rupture.
