A filter element for filtering fluid, comprising annular filter media extending axially between first and second axial ends, an annular ring at said first axial end and having a plurality of spokes extending radially inwardly therefrom to a central hub.
A filter element for filtering, fluid, comprising filter media having a perimeter, a reinforcement hand along at least a portion of said perimeter and performing a support function thereat upon attempted percussive cleaning of said filter element b service personnel striking said perimeter against an impact surface, wherein said filter media is annular and has a hollow interior extending axially between first and second axial ends, said first axial end being open and defining an axial flow path therethrough communicating with said hollow interior, said fluid flowing axially along said axial flow path through said open axial end, said reinforcement hand comprises a reinforcement ring at one of said axial ends and performing said support function thereat upon attempted percussive cleaning of said filter element by service personnel striking said one axial end against an impact surface, wherein said annular filter media has an outer circumference and an inner circumference and extends radially therebetween, said one axial end comprising an axially facing end face extending radially between said inner and outer circumferences, and said reinforcement ring is at at least one of said outer circumference, said end face, and said inner circumference, wherein said reinforcement ring comprises an annular ring member having a plurality of spokes extending radially inwardly therefrom to a central hub axially aligned with said hollow interior.
