Abstract
A filter assembly 10 includes a housing 12 defining a filter chamber having a first region forming a contaminated air inlet chamber 30 and a second region forming a clean air outlet chamber 40. A filter element 20 extends within the housing between the inlet chamber 30 and the outlet chamber 40. A flow barrier member 60 protrudes from the housing into a cooperating groove 70 provided in the end face of the filter element 20. The flow barrier forms a labyrinth type seal blocking contaminated air from bypassing the filter element.
