Liner for a filter sub-assembly
A liner for a filter sub-assembly has a wall having an outermost surface and an innermost surface. The innermost surface bounds a cavity extending between opposing first and second ends of the liner. A portion of the outermost surface is textured. The liner may be used in a rotor of a filter assembly.
