Abstract
An air filter has a round housing that is coaxial to a central axis of the air filter. The housing has a housing bottom part and a detachable housing cover. A round filter element is received in the housing. The housing bottom part has a tubular housing wall with an open end and an outlet-side axial end provided with a central outlet socket positioned axially opposite to the open end. Through the outlet socket, air exits from the air filter after filtration. The housing cover closes off the open end. A raw air region with annular cross section is formed between round filter element and inner side of the tubular housing wall. The housing cover has an annular or ring section-shaped air inlet region with inflow openings through which air to be filtered enters the housing without deflection in a direction coaxially or parallel to the central axis.
