Abstract
Systems and methods for coupling filter elements to at least one flange extending inside a housing are disclosed. In one aspect, a filter system may include a housing having an inlet, an outlet, a first end, a second end, a sidewall extending between the first end and the second end, a longitudinal centerline, and at least one flange extending inside the housing; and a plurality of filter elements located inside the housing, the plurality of filter elements each including an end shaped to couple directly to the at least one flange.
Claims16
A filter system, comprising:
- a housing having an inlet, an outlet, a first end, a second end, a sidewall extending between the first end and the second end, a longitudinal centerline, and at least one flange extending inside the housing;
- and
- a plurality of filter elements located inside the housing, the plurality of filter elements each including an end shaped to couple directly to the at least one flange,
- wherein the at least one flange is a single annular flange, and
- wherein the single annular flange is C-shaped.
