Abstract
A debris filter has a housing, a filter screen mounted to the housing and disposed so as to extend across a flow path through the housing, a debris extractor mounted to the housing, and a splitter bar also mounted to the housing. The debris extractor and the filter screen are so mounted to the housing as to enable rotation of the filter screen and the debris extractor relative to one another. The debris extractor has a debris intake opening and the debris extractor and the splitter bar are so mounted to the housing that the intake opening is positionable adjacent to or in juxtaposition with the splitter bar with the splitter bar overlapping and shielding the intake opening.
