Abstract
A filter device for adsorption of gaseous constituents from a gas flow includes a filter chamber with filters arranged therein, a clean-gas chamber connected to the first chamber in a fluid-conducting manner via the filters, and a collection chamber arranged beneath the filter chamber, is open toward the filter chamber and has an interior which narrows toward the bottom. An unfiltered-gas duct which leads from the outside, is arranged in the lower area of the collection chamber in such a manner that it can be adjusted in the direction toward the filters. A dust-discharge device, which leads toward the outside, is arranged in the lower area.
