The invention relates to a device for continuous filtration of impurities from a free-flowing mass, in particular a plastic melt, having a filter insert (3) in the form of a hollow rotating body rotatably mounted about its axis of rotation (A) with respect to a housing (1, 2) and through which the free-flowing mass flows, which rotating body is arranged in a flow channel of the housing (1, 2) between a feed channel (7) for the mass to be filtered and an outlet channel (8) for the filtered mass and having a discharge device comprising a transport screw (9) interacting with the filter insert (3), which discharge device is for impurities retained by the filter (5). In order to provide advantageous construction conditions, it is proposed that the filter insert (3) comprises a disk-shaped filter (5) coaxial to the axis of rotation (A) and arranged at the end side of the rotating body.
