Abstract
An apparatus for filtering mat forming suspensions, such as fibre pulp suspensions, has rotating annular discs (6) with peripheral chambers (13) arranged to operate as droplegs on the ascending parts of the discs. To speed up the emptying of the chambers there are venting means (21, 23) effective to supply air into the chambers at the upwardly moving parts of the discs, when the chambers are at least partly above a body of the suspension to be filtered during rotation of the discs.
