Cast formed filter and method of making the same
A cast formed filter and a method for making the filter are provided. The cast formed filter includes a cast formed filter media having an inlet end, an outlet end, a plurality of inlet openings, a plurality of outlet openings, and a fluid path. The plurality of inlet openings extend from the inlet end into the cast formed filter media, wherein a first portion of the cast formed filter media is disposed between each of the plurality of inlet openings and the outlet end. The plurality of outlet openings extend from the outlet end into the cast formed filter media, wherein a second portion of the cast formed filter media is disposed between each of the plurality of outlet openings and the inlet end, the second portion comprising at least a portion of the first portion of cast formed filter media. The fluid path extends through at least one of the plurality of inlet openings and through at least one of the plurality of outlet openings, wherein fluid flowing through the fluid path is filtered by the cast formed filter media.
1. A cast formed filter, comprising:
a cast formed filter media formed from a single structure, the single structure having an inlet surface, an outlet surface, and an exterior side extending from a peripheral edge of the inlet surface to the outlet surface;
a plurality of inlet openings located on the inlet surface, the plurality of inlet opening being spaced from each other, the plurality of inlet openings being formed at the same time as the single structure;
a plurality of outlet openings located on the outlet surface, the plurality of outlet openings being spaced from each other, the plurality of outlet openings being formed at the same time as the single structure; and
wherein a plurality of fluid paths are defined though the single structure, each of the plurality of fluid paths extending from the inlet surface into the cast formed filter media, wherein a first portion of the cast formed filter media is disposed in each of the plurality of fluid paths between each of the plurality of inlet openings and the outlet surface, and wherein each of the plurality of fluid paths extend from the outlet openings into the cast formed filter media, wherein a second portion of the cast formed filter media is disposed in each of the plurality of fluid paths between each of the plurality of outlet openings and the inlet surface, the second portion comprising at least a portion of the first portion of cast formed filter media; and wherein fluid flowing through the plurality of fluid paths is filtered by the cast formed filter media, wherein the cast formed filter media is formed from synthetic fiber.
2. The cast formed filter as in claim 1 , wherein the synthetic fiber is polyester fiber.
3. The cast formed filter as in claim 1 , wherein the plurality of inlet openings are a plurality of rows of inlet openings.
4. The cast formed filter as in claim 1 , wherein the plurality of inlet openings are a plurality of columns of inlet openings.
5. The cast formed filter as in claim 1 , wherein the plurality of inlet openings are a plurality of rows of inlet openings and a plurality of columns of inlet openings.
6. The cast formed filter as in claim 1 , wherein the plurality of outlet openings are a plurality of rows of outlet openings.
7. The cast formed filter as in claim 1 , wherein the plurality of outlet openings are a plurality of columns of outlet openings.
8. The cast formed filter as in claim 1 , wherein the plurality of outlet openings are a plurality of rows of outlet openings and a plurality of columns of outlet openings.
9. The cast formed filter as in claim 1 , wherein at least one of the plurality of inlet openings has a hexagonal cross-sectional shape.
10. The cast formed filter as in claim 1 , wherein at least one of the plurality of outlet openings has a circular cross-sectional shape.
11. A cast formed filter for a non-uniform shaped housing, comprising:
a cast formed filter media formed from a single structure and configured to be disposed in the non-uniform shaped housing, the cast formed filter media having an inlet end, an outlet end, a plurality of inlet openings, a plurality of outlet openings, and a fluid path;
the plurality of inlet openings extending from the inlet end into the cast formed filter media, wherein a first portion of the cast formed filter media is disposed between each of the plurality of inlet openings and the outlet end;
the plurality of outlet openings extending from the outlet end into the cast formed filter media, wherein a second portion of the cast formed filter media is disposed between each of the plurality of outlet openings and the inlet end, the second portion comprising at least a portion of the first portion of cast formed filter media, wherein the cast formed filter media is arranged in a non-uniform configuration complementary with a periphery of the non-uniform shaped housing; and
the fluid path extending through at least one of the plurality of inlet openings and through at least one of the plurality of outlet openings, wherein fluid flowing through the fluid path is filtered by the cast formed filter media and wherein the cast formed filter media is formed from synthetic fiber.
12. The cast formed filter as in claim 11 , wherein at least one of the plurality of inlet openings has a configuration that is not the same as a configuration of at least one of the plurality of outlet openings.
