Filter assembly

A filter connection base configured to be one of fluidly connected between a function port and a plurality of filter cartridges and removed such that one of the plurality of filter cartridges is installed directly on the function port, the filter connection base comprising:

• a central supply segment having a base inlet configured to be connected at the function port and supply a fluid from the function port through the central supply segment and toward the plurality of filter cartridges;
• a plurality of supply channels, each being configured to supply the fluid from the central supply segment to a cartridge inlet at a connection structure of each of the plurality of filter cartridges;
• and
• a plurality of discharge channels, each being configured to supply the fluid from a cartridge outlet at the connection structure of each of the plurality of filter cartridges to a base outlet of the filter connection base,
• the base inlet and the base outlet, and the cartridge inlet and the cartridge outlet, are configured to be identically disposed and dimensioned in relation to each other.

A filter connection base for fluidic connection of at least two filter cartridges to a function port, the filter connection base comprising:

• a base inlet disposed on a connection side of the filter connection base and fluidly connected to at least two supply channels configured to supply a fluid to a cartridge inlet of each of the at least two filter cartridges;
• a base outlet disposed on the connection side of the filter connection base and fluidly connected to at least two discharge channels configured to discharge fluid from a cartridge outlet of each of the at least two filter cartridges;
• and
• a fluidic connection structure formed on the connection side of the filter connection base by the base inlet and the base outlet and being configured to correspond with the cartridge inlet and the cartridge outlet of each of the at least two filter cartridges such that the filter connection base is interchangeable with each of the at least two filter cartridges to directly connect at the function port;
• a connector piece having at least one opening configured to supply the fluid from the function port to the at least two supply channels;
• wherein the connector piece is surrounded by a base body having the at least two supply channels, the connector piece and the base body being concentrically disposed and rotatable with respect to each other.

A filter assembly for fluidic connection at a function port, comprising:

• a connection base having a first side, a second side opposite the first side, a base inlet disposed on the first side, and a base outlet disposed on the first side, the base inlet being fluidly connected to supply channels for supplying a fluid to cartridge inlets of at least two filter cartridges, the base outlet being fluidly connected to discharge channels to discharge the fluid from cartridge outlets of the at least two filter cartridges, and
• wherein, the connection base with the base inlet and the base outlet has a fluidic connection structure corresponding to the cartridge inlets and the cartridge outlets of the at least two filter cartridges such that the connection base or a filter cartridge of the at least two filter cartridges is fluidly connected at the function port;
• wherein the base inlet is a component of a supply segment of the connection base, which ends in at least two of the supply channels;
• wherein the supply segment is a component of a tubular connector piece;
• wherein the connector piece has at least one orifice opening and is surrounded by a base body containing the supply channels, where the supply channels are fluidly connected to the base inlet via the at least one orifice opening of the connector piece;
• wherein each of the connector piece and the base body comprises a threaded portion such that a relative position between the connector piece and the base body is lockable.
