摘要： A thermally bonded filtration media that can be used in high temperature conditions in the absence of any loss of fiber through thermal effects or mechanical impact on the fiber components is disclosed. The filter media can be manufactured and used in a filter unit or structure, can be placed in a stream of removable fluid, and can remove a particulate load from the mobile stream at an increased temperature range. The combination of bi-component fiber, other filter media fiber, and other filtration additives provides an improved filtration media having unique properties in high temperature, high performance applications.

摘要： The fiber webs described herein may be incorporated into filter media and filter elements. The fiber webs may exhibit a high dust holding capacity. The fiber webs may also exhibit a low thickness. The fiber webs may be sufficiently flexible and/or deformable so that they may be processed to include a series of waves (also known as flutes) that extend along the cross-machine direction.

摘要： Disclosed are filter media packs having a single layer of a high loft filter media and a single layer of a low loft filter media, the filter media pack characterized by the absence of oil added to the filter media pack, the filter media pack capable of filtering air laden particulates from an air stream at greater than 94% efficiency at air stream flow rates of between about 100 feet per minute and 3000 feet per minute. Also disclosed are filter assemblies formed from the filter media pack, and methods of using the filter assemblies.

摘要： The fiber webs described herein may be incorporated into filter media and filter elements. The webs may exhibit a high permeability and stiffness, at a low thickness. The stiffness can be sufficient for the webs to be pleated to include sharp, well-defined peaks which can be maintained in a stable configuration during use.
