Patent number: 9346000Abstract: An air filter has a housing, a filter core, a resilient abutting element, a sleeve, a threaded rod bracket, a threaded rod and a nut. The axial sealing is achieved by axially compressing the resilient abutting element, such that the user does not have to apply much physical effort to compress the resilient abutting element. The user can easily push the filter core into the housing, and then rotates and tightens the nut, which can axially compress the resilient abutting element. It is easy to apply force on rotating the nut, and better still, the nut can be rotated by an electric tool, which further facilitates the convenience in assembling. Besides, the nut only abuts the sleeve, and the threaded rod bracket does not abut the filter core. Consequently, the filter core is not blocked, thereby making the air smoothly pass through the filter core.Type: GrantFiled: September 18, 2014Date of Patent: May 24, 2016Assignee: PRO-PURE INC.Inventor: Hsiang-Chi Lin

Patent number: 8827084Abstract: A filter element for a liquid filter is arranged in the liquid filter housing that has at least two housing parts such that an inlet of the housing for liquid to be filtered is separated from an outlet of the housing for filtered liquid. The filter element has a filter medium provided with a terminal disk. The terminal disk has a seal support for an outer radial annular seal that is to be clamped in a clamping area between the housing parts that are separable from each other. The seal support of the filter element has axially at least a base member and a cover member. The base member is fixedly connected to the terminal disk. The cover member is attached to the terminal disk, to the base member, or to terminal disk and base member. The annular seal is positioned between base member and cover member.Type: GrantFiled: February 1, 2012Date of Patent: September 9, 2014Assignee: Mann & Hummel GmbHInventors: Yihao Zhu, Rainer Loos, Bernd Nageldinger, Holger Schwarz, Norbert Strassenberger

Patent number: 8815086Abstract: A fluid filter assembly prevents the filter from moving when fluid is not flowing through the filter. The filter assembly of the invention includes a mounting ring mountable in the filter opening. The mounting ring has a mounting interface, which includes an axially extending portion and a radially outwardly extending flange that has a diameter greater than the filter opening. A rib extends radially outwardly from and circumscribes the ring. The rib is seatable within an annular groove defined within the filter housing and circumscribing the filter opening. When the rib is positioned in the groove, the filter is releasably secured in the opening.Type: GrantFiled: September 20, 2007Date of Patent: August 26, 2014Assignee: Pall CorporationInventor: H.

Publication number: 20140224748Abstract: Provided are filtration devices for purifying fluids from bioprocess applications and processes for using the same. The fluid filter elements or cells and fluid filter assemblies or capsules minimize upstream and residual volumes by the use of substantially flat interior surfaces. Desired pressure ratings are also met without the use of external equipment. Such capsules and assemblies can be disposable. The cells and capsules are in particular suitable for intermediate filtration volumes (150-2500 cm2 effective filtration area (EFA)) of biopharmaceutical processes. One or more of the following features are also provided by these cells and capsules: ergonomic connections, stand alone device with desired pressure rating, offer a small footprint when running in series or parallel, ability to monitor fluid level during operation, provide various EFA sizes to allow for use with minimal fluid volumes, and offer an integral seal between clean and dirty process fluid streams.Type: ApplicationFiled: September 4, 2012Publication date: August 14, 2014Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Deborah M. Bryan, Martin J. Blaze, Gokhan Kuruc
