1. A filter element comprising:
i) a body of media material having opposed first and second ends;
ii) first and second end cap assemblies, the first end cap assembly at the first end of the media material, the second end cap assembly at the second end of the media material, each of the first and second end cap assemblies including a first port for directing fluid into or out of the media material; and
iii) a shell of wound composite material closely encapsulating and retaining the body of media material and first and second end cap assemblies together, and defining an integrated pressure vessel;
wherein;
the shell of wound composite material has opposed first and second end portions, each end portion defines an opening;
the first end cap assembly includes a first portion and a second portion, the first portion having a smaller outer diameter than an outer diameter of the second portion, the first portion extending through the opening of the first end portion of the shell of wound composite material, the opening of the first end portion of the shell of wound composite material having an inner diameter that is smaller than the outer diameter of the second portion of the first end cap assembly;
the second end cap assembly includes a first portion and a second portion, the first portion having a smaller outer diameter than an outer diameter of the second portion, the first portion extending through the opening of the second end portion of the shell of wound composite material, the opening of the second end portion of the shell of wound composite material having an inner diameter that is smaller than the outer diameter of the second portion of the second end cap assembly.
