Abstract

A filter element arranged in a filter housing is provided with an annular filter medium flowed through by a liquid medium in a flow direction radial to a longitudinal axis of the filter element. A clean chamber is arranged in the flow direction of the liquid medium downstream of the filter medium. A filtered liquid medium outlet is fluidically connected to the clean chamber. A cylinder-shaped water separating screen is arranged in the clean chamber to separate water contained in the liquid medium. A water outlet opening fluidically connects the clean chamber to a water collecting chamber of the filter housing. A particle filter is arranged at the water outlet opening or arranged between the water outlet opening and the filtered liquid medium outlet of the filter element. The water outlet opening of the filter element is fluidically connected with the water collecting chamber of the filter housing.
