Abstract
Various embodiments relate to a filter element. The filter element includes a first endplate that defines a first endplate opening and a second endplate. Filter media is positioned between and extending axially between the first endplate and the second endplate. The filter media defines a central opening extending axially therein. A support structure is disposed within the central opening of the filter media and is attached to the first endplate and the second endplate. The support structure includes an axial lobed extension that extends from a first end of the support structure to a second end of the support structure. The support structure is configured to resist collapse of the filter element.

A filter element comprising:
- a first endplate defining a first endplate opening;
- a second endplate;
- filter media positioned between and extending axially between the first endplate and the second endplate, the filter media defining a central opening extending axially therein;
- and
- a support structure disposed within the central opening of the filter media and attached to the first endplate and the second endplate, the support structure comprising a plurality of axial lobed extensions that are spaced apart from one another, each axial lobed extension extending from a first end of the support structure to a second end of the support structure, the support structure configured to resist collapse of the filter element.
