Abstract
A demister for a gearing system includes a main body shaped as a disk having an inner annular rim coupled to an outer annular rim through a first wall and a second wall opposite from the first wall. A central opening is defined by the inner annular rim and extends between and through the first wall and the second wall. The main body is configured to be rotated about a central longitudinal axis to create centrifugal forces that separate oil mist particles from air. At least one fluid passage extends radially between and through the inner annular rim and the outer annular rim. The fluid passage(s) includes a fluid inlet opening in the outer annular rim and a fluid outlet opening in the inner annular rim. The fluid inlet opening is configured to accept incoming air. The fluid outlet opening is configured to discharge filtered air.
