Patent number: 11938438Abstract: 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.Type: GrantFiled: October 8, 2019Date of Patent: March 26, 2024Assignee: Oerlikon Textile GmbH & Co. KGInventors: Stephan Rickerts, Ernst Claussen, Hauke Petersen, Frank Knödler, Sonja Dittscher

Patent number: 11731070Abstract: 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.Type: GrantFiled: April 8, 2021Date of Patent: August 22, 2023Assignee: Oerlikon Textile GmbH & Co KGInventors: Rainer Matho, Andreas Mueller, Stephan Rickerts, Ernst Claussen, Hauke Petersen, Frank Knoedler, Sonja Dittscher

Patent number: 11549704Abstract: 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.Type: GrantFiled: April 8, 2021Date of Patent: January 10, 2023Assignees: Lufttechnik Gransee GmbH, Oerlikon Textile GmbH & Co KGInventors: Rainer Matho, Andreas Mueller, Stephan Rickerts, Ernst Claussen, Hauke Petersen, Frank Knoedler, Sonja Dittscher

Patent number: 8813689Abstract: A centrifugal fan with a pot-like impeller and with a housing, having a first circumferential wall region with an arc-like curvature which extends directly along the impeller. The housing includes in a direction of rotation of the impeller a second circumferential region with a radial distance from the impeller increasing spirally up to an outlet region. The housing includes in an opposite direction a third circumferential wall region extending to the outlet region, having an S-curvature and including a sub-region curved in the same direction as the first circumferential wall region forming a flow baffle element. Two side walls cover the axial end faces of the impeller wherein one of the side walls extends into the pot-like impeller and divides its interior into a first suction chamber having an intake and a second suction chamber. The outlet region expands in cross-section in the outlet flow direction.Type: GrantFiled: November 13, 2007Date of Patent: August 26, 2014Assignees: Punker GmbH, Alfred Karchner GmbH & Co.

Publication number: 20110044808Abstract: Proposed is a centrifugal fan with a pot-like impeller (10) and with a housing (11) accommodating the impeller (10), the circumferential wall (18) of which, starting from a first circumferential wall region (19) with an arc-like curvature which extends directly along the impeller (10), comprises on the one hand in the direction of rotation of the impeller (10) a second circumferential region (20) with a radial distance from the impeller (10) increasing spirally up to an outlet region (21) and on the other hand against the direction of rotation of the impeller (10) a third circumferential wall region (22) likewise extending to the outlet region (21). Two side walls (25, 26) cover the axial end faces of the impeller (10), wherein a partition (28) on one of the side walls extends into the pot-shaped impeller (10) and divides its interior into a first (V1) and a second (V2) suction chamber, an intake (29) being assigned to the first suction chamber (V1).Type: ApplicationFiled: November 13, 2007Publication date: February 24, 2011Inventors: Ernst Claussen, Joachim Peetz, Gerd Wegner, Ralph Seitter, Lutz Bauer
