Abstract
A filter includes a housing having a stack of filter disks arranged between an inlet and an outlet of the housing. At least some of the discs are formed with serrated edge at the upstream side of the filter disc stack, facing the housing inlet. The serrated edges are effective to increase the upstream filter surface and also from pockets for receiving dirt particles.
