1. A filter device, comprising:
a filter housing and a filter element defining a longitudinal axis disposed in the filter housing, the filter element defining a raw end and a pure end disposed radially inwards of the raw end with respect to the longitudinal axis, the filter element configured to be penetrated by a fluid flow in a radial direction from the raw end to the pure end of the filter element; and
a water separator fluidly connected to the pure end of the filter element and arranged coaxial to the filter element, the water separator disposed at an axial end of the filter element and arranged spaced apart axially outward from the same along the longitudinal axis downstream of the pure end, wherein the water separator includes a hydrophobic and annular diaphragm extending in an axial direction of the longitudinal axis configured to be penetrated by the fluid flow from a raw end of the water separator in a radially outward to a radially inward direction with respect to the longitudinal axis to separate water from the fluid flow,
wherein a flow channel is disposed axially between the filter element and the water separator and guides the fluid flow radially outwards from the pure end of the filter element to the raw end of the water separator.
