Rotating separator with housing preventing separated liquid carryover

A rotating separator for separating liquid from a fluid mixture, the rotating separator comprising:

• a housing having a sidewall with an inner surface;
• a first annular rotating separating filter element positioned within the housing and centered about an axis extending along an axial direction in the housing, the first annular rotating separating filter element having a first inner periphery defining a first hollow interior, and having a first outer periphery facing the inner surface of the housing and spaced along a radial direction radially outwardly from the inner surface thereby defining a first portion of a plenum therebetween;
• a second annular rotating separating filter element positioned within the housing and centered about the axis, the second annular rotating separating filter element having a second inner periphery defining a second hollow interior, and having a second outer periphery facing the inner surface of the housing and spaced along a radial direction radially outwardly from the inner surface thereby defining a second portion of the plenum therebetween;
• and
• the housing including an inlet for supplying the mixture to the first hollow interior, an outlet delivering a separated component of the mixture from second hollow interior, and a drain delivering separated liquid from the plenum.
