Abstract

A muffler for a filter system has a base body with an inlet opening. A fluid guiding rib is externally arranged on the base body so as to guide a fluid to be filtered by the filter system toward the inlet opening of the base body. The fluid guiding rib extends along a first flow direction, wherein the fluid to be filtered passes through the base body along the first flow direction. A filter system with a filter housing and a filter element removably received in the filter housing is provided with such a muffler. The muffler is attached to the filter housing.
