The filter construction has first and second opposite flow faces and is configured for a straight-through flow. The sealing system includes a frame construction and a compressible seal member. The compressible seal member is molded around a portion of the frame construction. The compressible seal member is sufficiently compressible to form a radial seal between and against the frame construction and a surface of a housing when the filter pack is inserted within the housing. | 12-15-2011 |
