Abstract

A rotary filter of the type described in U.S. Pat. No. 4,193,875 in which each of the filter disks, axially spaced on the rotating shaft, is subdivided into a plurality of sections or cells and each of the sections is connected by a tube to a fluid distributor or control head for evacuation, pressurization or the like. According to the invention, each of the passages connecting each section with the control head is formed by a unitary tube having an axially extending section, a bend and a radial section connected by the bend to the axial section. In the control head a disk fixed to the hollow shaft is provided in which the ends of the axial sections terminate removably and sealingly. The radial sections are fixed to the filter-segment carriers, e.g. by flanges and screws or bolts through these flanges.
