Patent number: 10677690Abstract: A test probe for filter leakage detection. The test probe (1) has an elongated housing (5) with a longitudinal inlet portion for admitting gas into a first chamber of the housing through an inlet of the inlet portion, and an outlet portion for letting gas out of a second chamber of the housing through an outlet of the outlet portion. Further, the test probe has an intermediate element comprising a throttling portion. The intermediate element is arranged between the inlet portion and the outlet portion, wherein the first and second chambers are fluidly interconnected via the throttling portion, wherein the throttling portion is elongated and extends longitudinally of the housing, wherein the throttling portion is arranged to cause a smaller vacuum upstream of the throttling portion than downstream of the throttling portion when gas is sucked through the test probe.Type: GrantFiled: December 14, 2016Date of Patent: June 9, 2020Assignee: Camfil ABInventors: Axel Mahler, Richard Addington, Kenny Hedlund

Patent number: 8080079Abstract: An air filter housing (1) has at least one filter chamber (2, 3) with an inlet end and an outlet end for air passing through a filter unit (F) disposed in the filter chamber, an access opening (4, 5) arranged in a sidewall of the filter chamber for the introduction of an air filter unit into and removal thereof out of the filter chamber, and a clamping device (8) for pressing an air filter unit disposed in the filter chamber against an end wall of the filter chamber in the inlet end thereof. The housing has a guide (19, 20, 21-24) for guiding an air filter unit (F) during introduction into and removal out of the filter chamber (2).Type: GrantFiled: March 14, 2006Date of Patent: December 20, 2011Assignee: Camfil ABInventor: Axel Mahler

Publication number: 20090288379Abstract: An air filter housing (1) has at least one filter chamber (2, 3) for receiving at least one filter unit (F), an access opening (4, 5) in a side wall of the housing leading to the filter chamber, a door (6,7) for closing the access opening and a clamping device (10, 11) for holding the at least one filter unit in abutment against a first end wall of the filter chamber. A portion (16) of the clamping device is, when a filter unit (F) is held by the clamping device (10, 11), sealingly in abutment with a circumferential portion (15) of the wall of the housing (1) in the second end of the filter chamber (2, 3) so that air or decontamination gas that has passed through the filter unit (F) can not enter the filter chamber outside of the filter unit.Type: ApplicationFiled: March 14, 2006Publication date: November 26, 2009Applicant: CAMFIL ABInventor: Axel Mahler
