Publication number: 20240091696Abstract: Air cleaner assemblies, components, and features are described. The features can be used to provide that the air cleaner assembly includes a housing and cover within which a filter cartridge having a media pack and a seal arrangement surrounding the media pack can be installed. The air cleaner assembly may also include a projection-receiver arrangement in which the filter cartridge has at least one first member and the housing has at least one second member that interacts with the first member. In one example, a portion of the seal arrangement is coplanar with the first member and a portion that is below the first member such that the first member is located between the seal arrangement and an inlet end of the filter cartridge.Type: ApplicationFiled: August 30, 2023Publication date: March 21, 2024Inventors: Kristof DECOSTER, Johnny CRAESSAERTS, Johan G. DEWIT, Bart CATOOR, Tim BILLIAU, Anthonius Jan-Baptist Maria MOERS, Rui SUN, Jacob C. SAVSTROM

Publication number: 20230001521Abstract: A fume extractor has an extractor housing (110, 210) defining an outlet (106, 206). A hose (120, 220) is coupled to the extractor housing that defines a first inlet (102, 202). A diffusion plate (130, 230) is coupled to the extractor housing that defines a plurality of openings (132, 232) cumulatively defining a second inlet (104, 204). A fan (280, 530) is disposed in the extractor housing, where the fan configured to connect each of the first inlet and the second inlet to the outlet. A first supporting surface (160) is opposite the diffusion plate relative to the extractor housing and a second supporting surface (170) at least 80° to the diffusion plate, where the first supporting surface and the second supporting surface are configured to selectively rest on a planar surface. The fume extractor defines a hose channel (140) configured to selectively receive the hose.Type: ApplicationFiled: December 3, 2020Publication date: January 5, 2023Inventor: Jacob C. Savstrom

Publication number: 20220387915Abstract: This disclosure describes a high performing (including, for example, high efficiency and low pressure drop) filter media. The filter media includes a support layer and a layer of fine fibers wherein at least some of the fine fibers in the fine fiber layer having an average diameter at least 3 times the average fiber diameter of a smaller fine fiber in the fine fiber layer. The fine fiber layer may include multiple layers of fine fibers. In some aspects, the smaller fine fiber may be present in the same layer of fine fibers as the larger fine fibers. Additionally or alternatively, the larger fine fibers may be present in a first layer of fine fibers and the smaller fine fibers may be present in a second layer of fine fibers.Type: ApplicationFiled: October 8, 2020Publication date: December 8, 2022Inventors: Patricia A. Ignacio-de Leon, Jacob C. Savstrom, Derek O. Jones, Klenton T. Willis, Thomas M. Weik

Publication number: 20220379249Abstract: This disclosure describes a filter medium that minimizes the adverse effects of variations in flow rate on filter medium efficiency without a corresponding increase in pressure drop. The filter medium includes a support layer, a continuous fine fiber layer, and an efficiency layer. The continuous fine fiber layer includes a continuous fine fiber that has a diameter of up to 10 micrometers and is located downstream of the efficiency layer.Type: ApplicationFiled: October 8, 2020Publication date: December 1, 2022Inventors: Derek O. Jones, Klenton T. Willis, Patricia A. Ignacio-de Leon, Thomas M. Weik, Jacob C. Savstrom

Publication number: 20220290887Abstract: Embodiments herein relate to monitoring systems that can learn patterns of filtration system operation and then use the learned patterns to monitor ongoing filtration system operation/performance. In a first aspect, a monitoring system for an air filtration system is included having a control circuit, and a pressure sensor, wherein the pressure sensor is in electronic communication with the control circuit. The monitoring system can be configured to store data reflecting signals of the pressure sensor, evaluate the stored data representing a first time period to derive a valve operating pattern, and compare data from the pressure sensor obtained after the first time period against the derived valve operating pattern to identify an abnormal valve event.Type: ApplicationFiled: March 15, 2022Publication date: September 15, 2022Inventors: Chad M. Goltzman, Charles E. Kotasek, Peter P. Vitko, Xiaobin Wang, Matthew J. Anderson, John H. Chastain, JR., Jacob C. Savstrom
