Distributor assembly, in particular for a separation unit of a modular process device arrangement

A distributor assembly for a separation unit of a modular process device arrangement, comprising:

• a fluid distributor device having a housing, a working port accessible through an open side of the housing, and a plurality of fluid ports,
• the fluid distributor device in fluid communication with the separation unit via a connection between a fluid inlet or a fluid outlet of the separation unit and the working port, and
• the fluid distributor device being adapted to selectively establish and block fluid communications between the plurality of fluid ports and between the plurality of fluid ports and the working port,
• a connecting element, and
• a retaining element,
• wherein the connecting element is adapted to be attached to one of the fluid ports,
• wherein the distributor assembly includes an associated mounting slot at the one of the fluid ports, and
• wherein the mounting slot is adapted to a shape of the retaining element such that the retaining element is insertable into the mounting slot up to a defined retaining position, in which the retaining element engages the connecting element and fixes it in place, and
• wherein the connecting element is
• a connector having a flow duct which is defined by a wall and opens into two opposite open ends, wherein in a fixed state of the connector to the one of the fluid ports, one of the open ends of the connector is aligned with the one of the fluid ports, or
• a functional unit which, in a fixed state to the one of the fluid ports, is in fluid communication with the one of the fluid ports.
