Abstract
A filtration system for filtering a fluid is described herein. The filtration system includes a filter element. The filter element includes a filter media that is structured to filter a fluid. The filter element also includes a first endplate, a second endplate, and a standpipe positioned radially within the filter media and coupled to the second endplate. The standpipe includes a first portion having a cylindrical shape and a second portion having a conical shape, the second portion downstream of the first portion.
Claims5
A filter element comprising:
- a filter media, the filter media structured to filter a fluid;
- a first endplate coupled to the filter media at a filter media first end;
- a second endplate coupled to the filter media at a filter media second end, opposite the filter media first end;
- and
- a standpipe positioned radially within the filter media and coupled to the second endplate, the standpipe comprising:
- a first portion extending away from the first endplate in a direction towards the second endplate, an inner surface of the first portion having a cylindrical shape;
- and
- a second portion extending away from the first portion towards the second endplate, an inner surface of the second portion having a frusto-conical shape with a radius that increases from a minimum radius at a second portion first end to a maximum radius at a second portion second end,
- wherein the first endplate comprises a first opening and a second opening, the first opening positioned radially within the second opening, the first opening sized to receive at least a portion of the standpipe therein.
