The collection assembly has a one-piece frame (88) and a cover (90) attached to an open rear end (96) of the frame (88). The filter element (89) is permanently attached to the cover (90) on an interior side. The cover (90) has ribs (124) that space the filter element (89) from a rear side (122) of the cover (90) and form an air flow space between the filter element (89) and the cover (90). The cover (90) is mounted on a flange (112) of the frame (88) with a frictional air-tight connection.
