Abstract
The invention relates to a tank vent filter () that guides tank contents that have inadvertently reached the tank vent filter () through a downpipe () past a first filter () of the tank vent filter (). A contamination of the first filter () is thus prevented by means of a space-saving arrangement. The downpipe () and the first filter () are preferably arranged rotationally symmetrically around the longitudinal axis of the tank vent filter () in order to achieve an especially compact design of the tank vent filter ().
