Abstract
A filter apparatus for removing contaminants from a fluid comprises a cylindrical body and first and second caps coupled to first and second ends of the cylindrical body. Each of the caps has an aperture therein for the flow of fluid therethrough and first and second filters are positioned within said first and second caps respectively such that a filter medium is housed within said cylindrical body and restrained by said first and second filters. The first and second filters are continuously cleaned by impinging multifaceted beads. The filter apparatus is entirely symmetrical and either the first or second cap may serve as an inlet cap while the other cap serves as an outlet.
