A centrifugal separator includes a frame and a drive member configured to rotate a rotating part in relation to the frame around an axis of rotation. The rotating part includes a centrifuge rotor closing a separation chamber. The separation chamber includes a stack of separation discs arranged coaxially around the axis of rotation at a distance from each other such as to form passages between each two adjacent separation discs. The stack of separation discs includes a first type of separation discs having an outer diameter of A or below, and at least one separation disc of a second type having outer diameter B or above, wherein diameter B is larger than diameter A. At least one of the separation discs of the second type is arranged at a position in the disc stack that is within the upper 15% of the total number of separation discs and at least one of the first type of separation disc is arranged axially above the uppermost separation disc of the second type.
