    • A filter and method of making is provided. The method comprising: forming a plurality of sheets of filter media, each sheet of filter media having an inlet end and an outlet end, wherein each of the plurality of sheets of filter media are formed by the steps of: thermoforming a first layer of filtration media to have a plurality of channels, the first layer having an upper surface and a lower surface; sonically welding a portion of a second layer of filtration media to the first layer of filtration media to form the sheet of filtration media, the sheet of filtration media having a plurality of fluid channels each having an inlet opening at one end of the sheet and a sealed end at another end of the sheet; and securing the plurality of sheets together by applying a strip of adhesive between each upper surface of each first layer facing the second layer of another sheet of filter media stacked upon the upper surface of the first layer of the filtration media.
    • 提供了一种过滤器和制造方法。 所述方法包括:形成多个过滤介质片,每片过滤介质具有入口端和出口端,其中所述多个过滤介质片中的每一个通过以下步骤形成:热成型第一层过滤 介质具有多个通道,所述第一层具有上表面和下表面; 将第二层过滤介质的一部分超声波焊接到第一层过滤介质以形成过滤介质片,该过滤介质片具有多个流体通道,每个流体通道在片材的一端具有入口开口, 密封端在片的另一端; 以及通过在层叠在所述过滤介质的第一层的上表面上的另一片过滤介质的第二层的每个第一层的每个上表面之间施加一粘合剂条来将所述多个片固定在一起。
