Abstract
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 () held by a filter holder () in said airflow substantially perpendicular to a main flow direction thereof and including a plurality of preferably stick-shaped filter elements () neighboring 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 () 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. Contrary to the prior art where the filter layer is usually enclosed in a tubular flow channel, the present invention avoids such flow-control-elements for guiding the air stream through the filter layer and/or preventing the airflow from diverging away from the filter layer, wherein in particular the filter layer, at its open side, is dispensed with flow-control-elements such as flow guiding surfaces, flow channel walls, fences or housing walls surrounding the filter layer.
