ABSTRACT:
A filtering system for filtering particles from a flow of fluid is disclosed, and includes a filter device for removably positioning in a lumen of a pipe carrying the flow of fluid. The filter device has an upstream side for positioning in an upstream direction of fluid flow and a downstream side for positioning in a downstream direction of fluid flow. The filter device comprises a perimeter rim extending along the perimeter edge of the filter device and defining an opening, and a plurality of filter bars extending across the opening to form a plurality of slots therebetween. Each of the filter bars of the plurality of filter bars has a transverse cross sectional shape. The transverse cross sectional shape has a transverse width toward the upstream side of the filter device that is relatively wider than the transverse width toward the downstream side of the filter device.
