    摘要: 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.
