Publication number: 20170001137Abstract: An air filter device includes an air flow intake, an air outlet and at least one air filter including a filter medium capable of removing particulate material and/or airborne molecular contamination (AMC) from an air flow passing through the filter. The amount of salt entrapped by the filter medium is determined, and the filter device is arranged to be able to provide an output corresponding to the salt load value. A method of monitoring the filtration condition of a filter uses a filter monitoring system, which includes the air filter device and a control. The control includes a memory and a processor. The memory is arranged to store computer readable code that executes the method.Type: ApplicationFiled: December 19, 2013Publication date: January 5, 2017Inventor: Erik Lans

Patent number: 9522355Abstract: A filter unit comprising a filter bag for removing particles from an air or gas flow, wherein the filter unit is arranged to receive at least one filter pocket and the filter bag comprises an opening portion and an end portion opposite said opening portion. The filter unit further comprises a frame arranged at a periphery of the opening portion, and a support structure arranged at the periphery of the end portion for stretching an area of the end portion. The frame and the support structure act to stretch the filter bag into a substantially parallelepiped shape such that the filter unit is arranged to provide a free passage for the at least one filter pocket into and out of said filter bag. Furthermore, the filter unit is arranged to fold between the frame and the support structure into a folded state.Type: GrantFiled: September 28, 2012Date of Patent: December 20, 2016Assignee: CAMFIL ABInventors: Joshua Kohn, Erik Lans

Patent number: 9056270Abstract: An air intake includes an air channel for an air stream passing through the air intake into the plant, and a particle filter assembly arranged in the air channel for removing particles from an air stream passing through the air channel, the particle filter assembly including a front and a back filter unit. The front filter unit is arranged before and in series with the back filter unit such that an air stream passing through the air channel passes through the front filter unit before passing through the back filter unit. The front filter unit is removable and replaceable by a fresh front filter unit while the back filter unit remains in the air channel and while an air stream is passing through the air channel during operation of the plant. The front filter unit has at least equal efficiency and dust holding capacity as the back filter unit.Type: GrantFiled: December 18, 2009Date of Patent: June 16, 2015Assignee: CAMFIL ABInventor: Erik Lans
