Patent number: 9566504Abstract: The present invention relates to an air cleaner for removing air pollutants from an air stream, for instance such as the cleaning exhaust/intake gas of an amusement machine, said air cleaner comprising a filter device including at least one filter layer (4a, 4b) held by a filter holder (5) in said airflow substantially perpendicular to a main flow direction thereof and including a plurality of preferably stick-shaped filter elements (6) neighbouring each other. In accordance with the present invention, the filter device has no closed surrounding along the circumference of the filter layers, but provides for an open side along at least a portion of the periphery of the filter layer. At least one circumferential side section (7, 8) of the filter layer parallel to or tangential to the longitudinal axis of an outermost filter element is formed as an open side free of flow control elements surrounding the filter layer.Type: GrantFiled: February 26, 2014Date of Patent: February 14, 2017Assignees: NOVOMATIC AG, DEXWET USA LLCInventors: Christoph Bichl, Heinz Winkler, Alois Homer, Erich Petein, Maximillian Vojta
