Estimating the term…
In accordance with certain techniques for filtering contaminated air, the air is sucked through at least one filter element, which is exchangeably held in a filter-holding device of an air duct system. In order to enable continuous filtering without process interruption, a plurality of filter elements is stored in the filter-holding device in such a way that, when one of the filter elements is removed, the soiled filter element is automatically replaced in the air duct system. For this purpose, the filter-holding device has a plurality of filter chambers, which are arranged relative to one another in such a way that, in the event of an exchange, the filter element can be slidingly guided from one of the filter chambers into another filter chamber.
A method for filtering contaminated air, in which air is suctioned through at least one filter element, and in which the at least one filter element is held so as to be replaceable in a filter receptacle installation of an air duct system, wherein a plurality of filter elements is held in the filter receptacle installation in such a manner that an automatic replacement of a contaminated filter element of the at least one filter element in the air duct system takes place when one of the filter elements is retrieved, and wherein the filter elements of the plurality of filter elements are held in filter chambers that are disposed on top of one another and, when replacing the contaminated filter element, are connected to one another so as to form a gravity chute.
A device for filtering contaminated air, having an air duct system which has an air inlet, an air outlet, and a filter receptacle installation, wherein the filter receptacle installation is constructed and arranged to receive a plurality of filter elements and hold at least one filter element between the air inlet and the air outlet, and wherein the filter receptable installation has a plurality of filter chambers which are mutually disposed in such a manner that a filter element when being replaced is able to be guided in a sliding manner from one of the filter chambers into another filter chamber.
