Abstract:
A filter arrangement comprising:(a) a housing having an interior; a gas flow inlet; a gas flow outlet; and a liquid flow outlet;(i) said gas flow inlet for receiving gases having an entrained liquid therein;(b) a coalescer filter oriented in said housing interior downstream of said gas flow inlet oriented for passage of gases received by said gas flow inlet;(i) said coalescer filter comprising non-pleated polyester fiberous filter media;(A) said non-pleated polyester fiberous filter media being non-cylindrical and having a first side and an opposite second side;(ii) said coalescer filter separating a liquid phase from the gases having the entrained liquid by straight through flow from said first side to said second side;(iii) said coalescer filter being removable from and replaceable in said housing interior:(c) a pleated barrier filter oriented in said housing interior downstream of said coalescer filter;(i) said pleated barrier filter oriented to remove at least some particulates from gases received from said coalescer filter;(ii) said pleated barrier filter being removable from and replaceable in said housing interior;(d) a liquid collection arrangement oriented for receiving liquid collected within said coalescer filter and drained therefrom; and(e) a baffle member extending between said coalescer filter and said pleated barrier filter;(i) said baffle member extending between said second side of said non-pleated polyester fiberous filter media and said pleated barrier filter to block a direct straight line gas flow from said coalescer filter to said pleated barrier filter.
