A filter appliance, comprising:
- a ring filter element having a longitudinal axis and arranged in a filter housing, the ring filter element having an axially upper end disc and an axially lower end disc,
- a collection pot arranged on the lower end disc and defining an opening, the collection pot including an axially projecting pin and at least one key profile protruding radially, wherein the pin and the at least one key profile are circumferentially spaced from one another,
- a function element having an insertable portion configured to be inserted into the opening of the collection pot and an end portion including a channel configured to receive the pin, and
- a lock profile disposed on the end portion of function element, wherein the lock profile is configured to receive the at least one key profile of the collection pot,
- wherein the filter appliance is operational when the pin engages in the channel and the at least key profile engages in the lock profile.
A ring filter element for a filter appliance, comprising:
- an annular filtering material having a first axial end and a second axial end, the filtering material surrounding an interior space defining a central axis;
- a water collection pot coupled to the first axial end with a water separator arranged therein, the water collection pot having an opening arranged coaxial with the interior space with respect to the central axis;
- an axially projecting pin and key profile disposed on an outer circumference of the water collection pot facing away from the central axis, wherein the pin and the at least one key profile are arranged circumferentially spaced from one another;
- a carrier element including a carrier portion insertable into the interior space of the filtering material via the opening of the water collection pot and a guide disposed on an axial end portion, wherein the guide includes a channel configured to receive the pin and a lock profile configured to receive the key profile when the carrier element is in an installed position;
- wherein the carrier element is in the installed position when the key profile engages in the lock profile in response to the pin engaging in the channel.
