    • Filter media includes a first layer of porous filter media having first and second opposite sides and first and second edges; a first porous screen oriented on the second side of the first layer of porous filter media, the first porous screen having first and second edges; a second layer of porous filter media having first and second opposite sides and first and second edges, the second side of the second layer of porous media oriented on the first porous screen, a first sealant securing the first layer, first screen, and second layer together adjacent to the first edges of the first layer, first screen, and second layer; a second screen oriented on the first side of the second layer, the second screen having first and second edges; and a second sealant securing the second screen and the second layer adjacent to the second edges of the second screen and second layer. The filter media can be coiled into a filter element resulting in a plurality of dirty fluid inlets between the first layer second side and second layer second side, and a plurality of clean fluid outlets between the first layer first side and second layer first side. Methods of making filter elements include providing a four layered construction of media, screen, media, and screen, and then coiling it into a filter element.
    • 过滤介质包括具有第一和第二相对侧以及第一和第二边缘的第一层多孔过滤介质; 第一多孔筛,其定向在所述第一多孔过滤介质层的第二侧上,所述第一多孔筛具有第一和第二边缘; 具有第一和第二相对侧和第一和第二边缘的第二层多孔过滤介质,所述第二多孔介质层的第二侧定向在第一多孔筛上,第一密封剂,其固定第一层,第一筛网和第二层 一起邻近第一层的第一边缘,第一屏幕和第二层; 第二屏幕,其定向在所述第二层的第一侧上,所述第二屏幕具有第一和第二边缘; 以及第二密封剂,其将所述第二屏幕和所述第二层固定在所述第二屏幕和第二层的第二边缘附近。 过滤介质可以卷绕到过滤元件中,导致在第一层第二侧和第二层第二侧之间的多个脏流体入口,以及在第一层第一侧和第二层第一侧之间的多个清洁流体出口。 制造过滤元件的方法包括提供介质,筛网,介质和筛网的四层结构,然后将其卷绕成过滤元件。
