Abstract
A method for filtering out particles from a fluid is disclosed, wherein unfiltered fluid is guided into a filter housing of a filter apparatus and filtered fluid is guided from the filter housing, and wherein a rotary filter element, which has a filter structure and is arranged in the filter housing and is rotatable about an axis thereof, is rotated at a speed which is sufficiently high that all particles passing in a fluid flow into the area of the rotary filter element are affected by its structure and are ejected therefrom, whereas the fluid passes the structure of the rotary filter element substantially freed from the particles and flows off from the filter housing.
