Abstract
A method for keeping a screen surface or a filter surface clean, wherein a pressure fluid is introduced from a conduit to a secondary side of a screen/filter drum, which fluid flows, during an underpressurized stage caused by blades of a rotor rotating on a primary side of the screen/filter drum, through the screen/filter drum from the secondary side to the primary side thereby rinsing the openings of the drum and making them clear.
