The filterpresses are equipped with a hydraulic power unit, for the automatic control of the opening-closing cycle of the plates. A group of probes located in the filtered water collection channel determines the end of filtration. An automatic system for shaking the plates makes it easier for the mud panels to detach from the plates. Moreover, the filterpresses can be equipped by a sliding tray collecting the dripping water, by a platform and a supporting structure complete with ladder and railings.
