Abstract
A filter device for filtering a liquid which includes trash. The device includes a drum for receiving the liquid and trash, wherein the drum includes at least one drum aperture. The device further includes a first pair of filter panels which are adapted for filtering the liquid. The filter panels are spaced apart to form a cavity for receiving the liquid and trash. The device further includes a frame for supporting the filter panels, wherein the frame is coupled to the drum. The frame includes a frame aperture wherein the frame aperture and the cavity form a volume having a cross sectional area sized substantially equal to or greater than the drum aperture and wherein said volume extends to a second pair of filter panels to enable liquid and trash which pass through the drum aperture to also pass through the frame aperture to the second pair of filter panels.
