Abstract
This disclosure generally relates to perforated filter media and coalescing filter elements utilizing perforated filter media. One example coalescing filter element is structured to separate a dispersed phase from a continuous phase of a mixture. The filter media includes a first coalescing layer. The first coalescing layer includes a first filter media. The first filter media has a plurality of pores and a first perforation. Each of the plurality of pores is smaller than the first perforation. The first perforation is formed in the first filter media and extends through the first filter media. The plurality of pores are structured to capture a portion of the dispersed phase. The first perforation is structured to facilitate the transmission of coalesced drops of the dispersed phase through the first coalescing layer such that the coalesced drops of the dispersed phase are separated from the portion of the dispersed phase captured in the first coalescing layer.
