| 055500000 | Flexible sheet type maintained in nonplanar configuration | 9 |
| 20100011725 | REINFORCED FILTER ELEMENT - The present invention provides one or more reinforcing members configured to act together with the adhesive bonding between filter media layers to further resist axial deformation forces such as induced by fluid flowing through the filter and thereby acting to retain the structural form and integrity of the filter element. Also disclosed is a method of reinforcing layers of a multilayer axial filter element against displacement of the layers. | 01-21-2010 |
| 20100170211 | Intake Air Cleaner - An intake air cleaner element for an internal combustion engine is described. It consists of a winding filter, the winding filter being flown through axially and featuring in the area of one front end at the circumference a sealing and/or fastening element. In the center of the winding filter an end-to-end cavity is provided. At least at one front end of the winding filter one autonomous cap is located for closing the cavity. | 07-08-2010 |
| 20090241494 | Seal arrangement for filter element; filter element assembly; and, methods - A filter element arrangement is provided which includes a media pack comprising Z-filter media, a preform and an overmold sealing a portion of the interface between the preform and the media pack, and also forming an air cleaner seal for the filter element. The overmold preferably comprises molded, foamed, polyurethane. A variety of media pack shapes can be used. | 10-01-2009 |
| 20110314782 | PLEATED AIR FILTER PACK AND AIR FILTER USING SAME - The invention provides a filter pack of which the mass is not increased, and moreover, the effective filter medium area is not reduced, and of which the pressure drop is sufficiently low, and the strength is sufficiently high, and an air filter using this. | 12-29-2011 |
| 20120000170 | Filter Element - A filter element, and filter apparatus, include a filter pack, a seal member, and a seal support frame operatively connecting the seal member to the filter pack. The seal support frame includes an annular extension, which is preferably canted at an oblique angle to a longitudinal axis, for supporting the seal member. The seal support frame also preferably includes a first end thereof including the annular extension, and a second end thereof spaced from the first end thereof along the longitudinal axis, with the first and second ends of the seal support frame joined by a hub of the outer peripheral sidewall of the seal support frame to define a cavity within the seal support frame for receiving the filter pack. The first and second ends of the seal support frame, and the filter pack are preferably joined and sealed to one another by a single bead of adhesive. | 01-05-2012 |
| 20120124951 | AIR DUCT SCREEN AND METHOD OF USE - A duct screen mountable in an air duct for retaining objects which pass through an associated register, the screen having a filtering base having a plurality of holes and a frame to hold the filtering base in place within the air duct. | 05-24-2012 |
| 20110265437 | FILTER ELEMENT HAVING SEALING MEMBERS AND METHODS - A filter arrangement includes a media construction comprising a corrugated sheet secured to a flat sheet rolled into a coiled construction. A frame and a first seal member are provided. The frame secures the first seal member to the coiled construction. The first seal member is preferably oriented to form a radial seal with a housing. A second seal member is secured to the outer annular surface of the coiled construction. The second seal member includes a gasket extension having first and second opposite ends; an attachment portion; and a protrusion extending from the attachment portion. The second seal member is preferably oriented to form an axial seal with a housing. Air cleaners preferably utilizing filter arrangements as described herein operably installed within housings. Methods of installing, filtering, assembling, and servicing preferably include arrangements as described herein. | 11-03-2011 |
