A filter press, for cake or precoat filtration, including one or more filter units, each of which includes slurry frames, filter plates, and support sheets or surfaces. Each of the filter plates is provided with at least one filtrate discharge, and each support sheet or surface, which is disposed on one side of a given filter plate, has associate therewith one of the slurry frames, which has a filling space which is directed toward the caking side of the support sheet or surface, an upper and lower connection for venting and discharge, and a supply conduit for medium which is to be filtered. Associated with each of the slurry frames is a distribution chamber which communicates with the filling space of one of each of the support sheets or surfaces, which are in a sealed state with the slurry frame via a press border. The communication is established via a partition which borders one of the filling spaces and extends parallel to the support sheet or surface. In the vicinity of the frame, the partition is provided with a fluid opening. The supply conduit has an opening into the center of the distribution chamber, with the opening being directed against an adjacent partition surface, from which it is spaced. While providing for uniform caking of the filtering aid, the filtration output is increased considerably. At the same time, it is possible to remove the filtration residue from the filling spaces while the filter unit remains closed.
