摘要： A replaceable, rectangular, flat, selectively permeable filter element (1) for the framelike section (27, 30) of a sheet filter device (20) consisting of metal and/or hard plastic for the filtration of fluids (liquid and/or gas) can be clamped in by its edge in a leak-proof manner and like a sandwich between a housing part (30) on the sediment chamber side and a housing part (27) on the filtrate chamber side and supported against the pressure gradient on a draining housing support plate (27), whereby the sediment chamber and the filtrate chamber are provided with connections (22, 25) for supplying and emptying the housing chambers. The flat filter element (1) is formed by a flat filter band pleated into a plurality of close folds and adapted to the inside dimension of a hollow chamber (30) in length, width and depth, whereby it essentially fills up this inside dimension, whereby the open folds and the web backs of one side of the pleating face the sediment chamber (41) and the open folds and the web backs of the other side face the filtrate chamber (47), and the pleating, formed to a flat cuboid (plate), of the filter band blank constructed with at least one layer is surrounded in a frame-like manner by a plastic seal (6) and the latter is provided with a formed sealing flange (7) with which the filter cassette can be clamped in a leakproof manner between the housing parts. The pleating is covered on both sides by a support grid (10, 11) whose edges are anchored in order to brace the filter cassette in the material of the seal (6) and/or of the sealing flange (7).
