Abstract

A multi-disk rotary filter in which a plurality of disks on a common shaft are partly immersed in a trough containing the suspension to be filtered and each of the filter disks is formed with a plurality of filter sectors or cells each connected to a control disk through which the filtrate is evacuated. According to the invention, each disk is formed with a cell carrier with a radial passage communicating with each sector and merging into an axial passage. The axially extending passages of at least some of the disks are formed at least in part by straight tube sections outwardly of the shaft.
