1. A filter assembly, comprising:
a housing defining an internal volume and an outlet fluidly connectable to an oil system;
a filter cartridge removably received within the internal volume of the housing; and
an inlet conduit defining an inlet fluidly connectable to the oil system, the inlet conduit being in fluid flow communication with the internal volume of the housing, the inlet conduit including first and second sections being transverse to one another, the inlet conduit having:
a wall circumscribing a main flow passage from the inlet to the internal volume, and
a sedimentation pocket defined by the wall, the sedimentation pocket extending downwardly away from the main flow passage and downwardly from an intersection between the first and second sections, and in a direction having a component parallel to a direction of a gravity when the filter assembly is in use.
