Rotating separator with single assembly orientation and integrated counterbalance

A filter element having a longitudinal axis and comprising:

• a first endplate including a center tube;
• and
• a second endplate including a central aperture having a perimeter, a second endplate interior side, a second endplate exterior side, and a first counterbalance mass formed on the second endplate exterior side;
• an axially extending slot formed on one of the first endplate and the second endplate;
• and
• an axially extending protrusion formed on one of the first endplate and the second endplate, the axially extending protrusion configured to engage with the axially extending slot.

A rotating separator comprising:

• a filter element extending axially along a longitudinal axis and comprising:
• a first endplate including a first central aperture;
• a second endplate coupled to the first endplate forming an interior cavity therein, the second endplate including a second central aperture;
• a central hub positioned axially between and coupled to the first endplate and the second endplate, the central hub comprising a center tube extending along the longitudinal axis;
• a first axially extending slot formed on one of the first endplate, the second endplate, and the center tube;
• a second axially extending slot formed on one of the first endplate, the second endplate, and the center tube;
• a first protrusion positioned on and extending along one of an interior side of the first endplate and an interior side of the second endplate and configured to engage with the first axially extending slot;
• a second protrusion positioned on and extending along one of the interior side of the first endplate and the interior side of the second endplate and configured to engage with the second axially extending slot;
• and
• a filter structure positioned within the interior cavity and configured to filter a contaminate from a fluid, the filter structure separated from the central tube by the central hub.
