Abstract: 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.

Abstract: A filter device for filtering particles from an air stream has an inlet channel through which the air to be purified flows, at least one filter element through which the air can flow and which is interchangeably held in a flow channel, and an outlet channel through which the purified air flows, an insertion chamber which can be closed by a door and from which a filter element can be fed to the flow channel, and an output chamber closable by a closure element, into which a filter element is feedable from the flow channel. The closure element of the output chamber is locked in the closed position via a locking mechanism when the door on the insertion chamber is opened and the output chamber and the insertion chamber are connected to the same flow channel.

Abstract: A filter device for filtering particles from an air flow has an inlet channel through which the air to be cleaned flows, at least one filter element through which the air can flow and which is held replaceably in a flow channel, and an outlet channel through which the cleaned air flows. The filter device has an insertion chamber which can be closed by a door and from which a filter element can be fed to the flow channel, and an output chamber which can be closed by a closure element and into which a filter element can be fed from the flow channel. A cover is attachable to the filter element, which covers a filter cake on the filter element so that the unit of filter element and cover is removable from the output chamber together.
