Abstract: In one example, a filter core includes a body with a generally cylindrical shape and a substantially hollow interior. The body includes a first annular wall disposed proximate a first end of the body, and a second annular wall disposed proximate a second end of the body such that the second annular wall is axially spaced apart from the first annular wall, and the second annular wall and the first annular wall extend toward each other. As well, the filter core includes a framework connected to the first annular wall and the second annular wall. The framework and the first and second annular walls cooperate with each other to define a group of openings, each of which communicates with the substantially hollow interior of the body, and the openings collectively define an open space of the filter core.
