<p>An apparatus for removing matter accumulated on a filter element, rotatable about a central axis, having an arm portion mounted at an angle relative to the radii extending from the central axis of the filter element and in a stationary position relative thereto. The arm portion supports a flexible means for engaging a surface of the filter element as the element is rotated relative to it frictionally remove the a?????lated matter from the surface. The arm and flexible means are preferably curved outwardly toward the periphery of the filter element to facilitate outward removal of matter while maintaining the integrity of the surface of the filter element.</p> |
