Abstract:
A filter coalescer cartridge for treating jet fuel including:a first layer of pleated fiberglass filter media having oppositely disposed facing surfaces formed in an annular array of individual parallel spaced apart pleats to commence water coalescence in the fuel being treated and to remove particulate contaminants therefrom; a second layer of pleated fiberglass filter media having oppositely disposed facing surfaces formed in an annular array of individual parallel spaced apart pleats to coalesce water in the fuel being treated and to remove particulate contaminants therefrom, said second layer of pleated filter media surrounding said first layer of filter media to form a nested pleated structure with said second layer of filter media such that outer facing peaks of the first layer of media fit within inner valleys of the second layer of media and inner facing peaks of the second media fit within outer valleys of the first layer of media; a screen support layer surrounding the outer surface of said second layer of pleated filter media; and an intermediate spacer layer disposed between said first and said second layers of pleated filter media, said spacer layer abutting an entire inner facing surface of the second layer of pleated filter media adjacent the one of the facing surfaces of said first layer of pleated filter media, and an outer facing surface of said first layer of pleated filter media.
