Abstract
An ion exchanger filter device has a housing with inflow opening and outflow opening for a medium that penetrate a wall of the housing. An ion exchanger cartridge is arranged in the housing. A flow path for the medium extends from inflow opening through the ion exchanger cartridge to outflow opening. The ion exchanger cartridge has a cartridge container with a receptacle that is delimited by a circumferentially extending wall provided with one or more outflow ports distributed circumferentially about the circumferentially extending wall. The receptacle is filled with ion exchanger material. The outflow ports, relative to the outflow opening, are arranged offset in axial direction of the ion exchanger filter device. The flow path has a deflection downstream of the outflow ports. The outflow ports, relative to a direction of gravity in intended mounting position of the ion exchanger filter device, are arranged axially above the outflow opening.
