Daxing Dryer Vac Roll for High Speed Paper MachineProduct name Vac roll Diameter range 700-1250mmFace lenh range 3000-14000mmWork speed 2800mpm Our performance The Vac roll in Dryer section normally is a grooved and drilled and used in the individual felt dryer section of high-speed paper machines. Air is sucked in through the holes on the roller shell, creating negative pressure in the grooves. Negative pressure keeps the paper in contact with the fabric, preventing operational issues such as paper shaking.
