FILTER SYSTEM FOR FILTERING FLUIDS

摘要

The filter system comprises a filter element (10) arranged in wave- or zig-zag-s haped folds and having flat filter element portions (12) and intermediate bending lines (14). The longitudinal edges of the filter element (10) are connected to tensioning bands (20). When the filter element (10) is stretched, these tensioning bands (2 0) are tensioned and in their tensioned condition fulfill a holding function for holding the filter element portions (12) in the s tretched condition of the filter element (10). Thus, no spacers are required on the filter frame (22) for maintaining the stability of s hape of the filter element (10).
