Abstract
A filter assembly (10) includes a housing (12) defining a chamber (14). A filter substrate (16) is disposed within the chamber (14) for filtering fluids passing therethrough. The housing 12 includes an inlet (22) disposed in fluid communication with the chamber (14) for allowing flow of fluid into the chamber (14). The chamber (14) defines a flow path between the inlet (22) and filter substrate (16) for perfecting fluid flow therebetween. An outlet (24) is disposed in fluid communication with the chamber (14) for allowing the flow of fluid to exit the chamber (14). A snagging element (26) is disposed within the housing (14) between the inlet (22) and the filter substrate (16) on the flow path for snagging and retaining gelatinous particulate material from the fluid prior to being filtered. A method of filtering gelatinous material from a flow of fluid includes the steps of snagging gelatinous material from the flowing fluid and then passing the fluid through a filter.
