Abstract
A filter pack includes a filter construction (100) and a sealing system (60) for sealing the construction within a duct or housing (305). The filter construction has first and second (110) opposite flow faces and is configure d for a straight-through flow. The sealing system (60) includes a frame construction (205) and a compressible seal member (250). The compressible se al member is molded around a portion of the frame construction. The compressibl e seal member (250) is sufficiently compressible to form a radial seal (172) between and against the frame construction (205) and a surface of a housing (305) when the filter pack (100) is inserted within the housing (305).</SDOA B>
