Abstract
A liquid filtering apparatus for mounting in a housing and positioned to filter liquid flowing from an inlet (23) to a drain. A rotatable wheel is disposed within and coupled to a rotating screen so that rotation of the wheel causes rotation of the screen. The wheel includes vanes (5 12) extending towards the screen dividing the space within the screen into sections substantially isolated from each other except via the drain. A stationary baffle (13) arranged adjacent a portion of the screen prevents liquid from flowing into the wheel through that screen portion. The baffle is positioned such that water flows more readily into sections of the wheel on one side of a vertical plane through the rotation axis than the other sections. Thus, the wheel is unbalanced by water retained in sections of the wheel and rotation of the wheel results.
