Patent ID: 8357218

Claim:
A filter element for filtering fluid, comprising annular filter media having an outer circumference, and an inner circumference defining a hollow interior, and extending axially between first and second axial ends, said first axial end having an axially facing end face extending radially between inner and outer circumferences, and an end cap at said first axial end and extending axially away from said end face in a first axial direction, said second axial end being axially spaced from said first axial end along a second axial direction, said first axial direction being opposite to said second axial direction, an annular outer liner extending axially along said outer circumference and extending in said first axial direction beyond said end face and into said end cap and providing a percussion band performing a support function upon attempted percussive cleaning of said filter element by service personnel striking said first axial end at said outer circumference against an impact surface, wherein said outer liner extending into said end cap has a reinforcement segment turned away from said outer circumference and radially inwardly toward said inner circumference and providing said percussion band, said reinforcement segment has a turn-back portion turned back axially in said second axial direction toward said end face, said turn-back portion has a termination end axially spaced from said filter media by a section of said end cap axially interposed therebetween.
