    摘要： A generally cylindrical filter element incorporating nonsymmetrical or asymmetrical V-pleated media. The V-pleated media provides increased filter media per given filter volume, extended filter life, and a smaller filter for equivalent filter life. A smaller filter is generally beneficial for some applications such as aircraft, due to its lower weight. Various features of the filter include asymmetric variable pleat heights applied to a cylindrical or obround filter; defined pleat spacing applied to a variable pleat height element; optimal pleat density; and optimal shape of inlet and outlet.

    摘要翻译： 通常为圆柱形的过滤器元件，其包含非对称或不对称的V形褶皱介质。 V型褶皱介质在给定的过滤器体积中提供增加的过滤介质，延长过滤器寿命，以及相当的过滤器寿命的较小过滤器。 由于较小的重量，较小的过滤器对于诸如飞机的一些应用来说通常是有益的。 过滤器的各种特征包括应用于圆柱形或椭圆形过滤器的不对称可变褶皱高度; 定义的褶皱间距应用于可变褶皱高度元件; 最佳褶密度; 和入口和出口的最佳形状。

    摘要： A filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face of the filtration media pack to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered fluid flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered fluid flowing out of the second portion of the plurality of flutes so that fluid passing into one of the first face and the second face of the media pack and out the other of the first face and the second face of the media pack passes through media to provide filtration of the fluid. The filtration media pack can be provided with increased filtration media compared with commonly used z-media packs. Techniques for increasing the amount of filtration media available for filtration include increasing the flute density, reducing masking, adjusting flute width height ratio, increasing flute density, adjusting flute shape, and reducing plug length. Techniques for increasing performance while reducing initial pressure drop are also provided. A filter element containing the filtration media pack is provided, and the filter element includes a seal member extending around a periphery of the filtration media pack. A method for manufacturing a filtration media pack and a method for using a filtration media pack are provided.
