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;
- 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, the first portion having a cylindrical shape;
- and
- a second portion extending away from the first portion towards the second endplate, the second portion having a radius that increases from a minimum radius at a second portion first end to a maximum radius at a second portion second end.
A filtration system comprising:
- a filter head having a first port and a second port;
- a filter cartridge comprising:
- a shell coupled to the filter head;
- and
- a filter element disposed within the shell, the filter element comprising:
- a 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, the first portion having a cylindrical shape;
- and
- a second portion extending away from the first portion towards the second endplate, the second portion having a radius that increases from a minimum radius at a second portion first end to a maximum radius at a second portion second end.
A filter cartridge comprising:
- a shell;
- and
- a filter element disposed within the shell, the 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;
- 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, the first portion having a cylindrical shape;
- and
- a second portion extending away from the first portion towards the second endplate, the second portion having a radius that increases from a minimum radius at a second portion first end to a maximum radius at a second portion second end.
