ABSTRACT:
A rotatable filter assembly comprises a rotor in a container for fibre suspension. The center of the rotor is formed by axial discharge tubes into which hollow filter elements, forming annular filter discs open. A collecting hopper extends into the center of the filter assembly. The filter elements keep separately, at least during part of the rotation turn, a lower pressure inside than outside. The filter assembly is characterized in that each of the axial discharge tubes (6) is permanently connected to its own accumulator chamber (9) for filtrate, which is provided to keep during a first part (16) of the rotation turn of said drum (4) such a pressure, preferably atmospheric pressure, that filtrate is caused to accumulate in the accumulator chamber (9), and that during a second part of the rotation turn of the drum (4) the accumulator chamber is caused to communicate with a device for filtrate discharge (11, 26) which is dimensioned to discharge the filtrate from tube and accumulator chamber during this second part of the rotation turn.
