Abstract
In a pressure filter for liquid media a plurality of filter elements is supported by a removable hollow cross bar which, when the filter tank is opened, can be removed together with all or groups of the filter elements. The filter element has a flexible filter wall and preferably an outer fine meshed wall and an inner coarse meshed wall. Between the two wall portions a packing material is arranged. Preferably the entire filter element is a flexible tube element. Spray tubes are arranged in the filter tank which are also removable together with their supporting carrier member. The spray elements serve to rinse out the filter cake. This may be done by passing the rinsing agent successively at spaced time periods through individual groups of the filter elements.
