Metal Multimantle Parallel Filter Element

The filter element consists of multiple metal filter cylinders of varying sizes nested concentrically, forming a parallel-flow structure; the nested layers distribute the flow simultaneously, significantly increasing the effective filtration area while minimizing flow resistance and enhancing contaminant-holding capacity.
It is commonly used in steam turbine lubrication oil stations and fuel supply systems, corresponding to the parallel-triple-element structure for steam turbine oil that you mentioned earlier.
