Ultra Low Vacuum Box Cover
The height difference between dewatering elements and 3-5Kpa external pressure make the pulp form slight turbulence and thus make the pulp redistribute on the wire to improve paper evenness and paper quality.
Recommended materials: Sicer-Sub A; Sicer-Gmd A; Sicer-Sub A + HDPE;
