Spiral filter press AKUPRESS A / AS

automatichigh-pressurefor sludge treatment

The AKUPRESS A is available in three sizes between 500 and 800 mm screw diameter that handle 70 to 200 dry tons of pulper reject per day. Here, the discharge opening allows that large particles directly exit the press zone. The high one-thread spiral enables the transportation of large particles without any blockings. The bearings on both sides support the entire high-pressure range, stabilize the screw shaft and thus ensure high availability. The interchangeable screen basket system makes maintenance easy. The user controls the process easily by adjusting the pneumatic pressure of the cone that exhibit the counterpressure at screw press outlet. The AKUPRESS AS line shares the process control and robust design with the AKUPRESS A, but it has a completely closed cover system and different screw geometries, thus providing best conditions for fine reject and pulp mill reject. For the latter suction openings are available for odour control. The AKUPRESS AS is available in five sizes from 250 to 800 mm screw diameter.
