Abstract: A filter media comprises a first fiber layer and a second fiber layer positioned downstream of the first fiber layer. The first fiber layer has a first geometric mean fiber diameter of less than 1 pm such that the geometric standard deviation of fiber diameter is greater than 2. The second fiber layer has a second geometric mean fiber diameter of less than 1 pm such that the geometric standard deviation of fiber diameter is less than 2.

Abstract: Composite filter media is formed from multiple layers of media material including a nanofiber media layer, where the layers are laminated, bound, or otherwise composited to each other. The composite filter media can comprise at least one nanofiber layer comprising polymeric media material having a geometric mean fiber diameter of about 100 nm to 1 μm, and fibers configured in a gradient such that ratio of the geometric mean diameter of fibers at the upstream face of the nanofiber layer to the geometric mean diameter of fibers at the downstream face of the nanofiber layer is about 1.1 to 2.8, preferably about 1.2 to 2.4.

Abstract: Cleanable filters and methods of cleaning filters are described in the present application. The cleanable air filter includes a housing and a filter element installed in the housing. The filter element is configured to filter an operating fluid in a given application. The filter element is cleanable in-situ in the installed condition in the housing. The cleanable air filter further includes a cleaning fluid applicator configured to apply a cleaning fluid to the filter element while the filter element is in the installed condition in the housing such that the filter element is cleanable without being removed from the filter housing.
Abstract translation: 在本申请中描述了可清洁的过滤器和清洁过滤器的方法。 可清洁空气过滤器包括安装在壳体中的壳体和过滤元件。 过滤元件被配置为过滤给定应用中的工作流体。 过滤元件可以在外壳中的安装状态下就地可清洁。 可清洁空气过滤器还包括清洁液施用器，其构造成当过滤元件处于壳体中的安装状态时将清洁流体施加到过滤元件，使得过滤器元件可清洁而不从过滤器壳体移除。

Abstract: A pleated filter media comprises a plurality of pleats comprised of pleat segments extending in an axial direction between first and second axial ends and extending in a transverse direction that is perpendicular to the axial direction between first and second sets of pleat tips at least partially defined by first and second sets of bend lines. Axial flow channels are defined between the pleat segments in the lateral direction and the plurality of pleats has a width in the transverse direction that varies along the axial direction.
