Polymer Filter Element | Process Filtration | John Crane


Replacement filter elements are produced in a variety of geometries, including conical (filter cone), cylindrical (filter candle/filter cartridge), or star-shaped (star elements). John Crane uses metallic nonwoven filter media with filter grades from 2 µm to 80 µm and wire meshes from 5 µm. The nonwovens consist of three-dimensional structures built from laid and sintered fibers. In addition, they exhibit high porosity and dust holding capacity and can be pleated. Wire meshes are available with different weaves (square mesh, long mesh, Dutch weave, etc.) and are characterized by clearly defined pore sizes, determined by the wire diameters and the weave.
