The AKUPRESS AX works with much higher torque than the AKUPRESS A/AS and thus provides the maximum mechanically possible dewatering performance. The high torque is controlled by an axial adjustment of the screen basket to the screw shaft and by continuous adaption of the press zone length to the respective sludge characteristics. The AKUPRESS AX is available in seven sizes from 250 to 1000 mm screw diameter, thus is able to handle up to 250 tons per day of waste paper reject.
