ABSTRACT:
A support structure of a filter element for supporting a filter material that is adapted to filter a fluid includes a first frame portion and a second frame portion. The first frame portion has a plurality of radially-extending fingers that are longitudinally spaced from one another. The first frame portion is disposed entirely on an unfiltered side of the filter material. A second frame portion has a pair of longitudinally-extending support surfaces that are disposed in a spaced, facing relationship with respect to one another. The second frame portion is disposed entirely on a filtered side of the filter material. The radially-extending fingers of the first frame portion and each of the longitudinally-extending support surfaces of the second frame portion support the filter material to define a first radial channel. The radially-extending fingers of the first frame portion space the longitudinally-extending support surfaces of the second frame portion apart from one another.
