ABSTRACT:
An apparatus is provided for the cleaning by compressed air of a plurality of separate filter elements, e.g. compact filter cells, grouped around a common center, which have their clean gas outlets situated in the bottom of a clean gas chamber common to the filter elements. A duct of gooseneck shape is connected at its inlet end to a compressed air source and is swivelably mounted so that its outlet end opens out over any one of the clean gas outlets of the filter elements at selectable stations. The duct flares out continuously within a considerable portion of its extension in a direction towards the outlet end, partly within a first and a second portion so that it prevents the expanding and expanded compressed air, respectively from not following the inside of the duct, and partly within a third, terminating portion at the outlet end of the duct which is shaped so as to form a belled portion.
