Header frame design for filter element
A filtration unit and a method of installing a filtration unit are provided. The rectangular filtration unit includes a filter element for filtering fluid. The frame includes a first portion and a second portion. The frame supports the filter element and the frame defines an opening. A first dimension of the filtration unit measured between the exterior of the first portion and the opening is greater than a second dimension of the filtration unit measured between the exterior of the second portion and the opening. In a further example, the filtration unit is mounted in a top section and a bottom section of a holding frame.
1. A method of installing a filtration unit, the method including:
providing a filter element for filtering fluid;
providing a rectangular frame including a first portion defining an upper-most peripheral edge of the frame, and a second portion defining a lower-most peripheral edge of the frame running parallel to the upper-most peripheral edge, the frame supports the filter element, and the frame defines at least one opening, the at least one opening providing a continuous and uninterrupted air entry-way and having an upper edge adjacent and parallel to the upper-most peripheral edge and a lower edge adjacent and parallel to the lower-most peripheral edge,
wherein a first dimension measured between the upper-most peripheral edge and the upper edge of the at least one opening is greater than a second dimension measured between the lower-most peripheral edge and the lower edge of the at least one opening; and
mounting the filtration unit in a top section and a bottom section of a holding frame.
2. The method of installing a filtration unit according to claim 1 , wherein the difference between the first dimension and the second dimension is greater than 1% of a third dimension measured between the exterior of the first portion and the exterior of the second portion.
3. The method of installing the filtration unit according to claim 2 , wherein the first dimension is greater than the second dimension and the second dimension is greater than a manufacturing tolerance for a fourth dimension measured between the first portion and the second portion.
4. The method of installing the filtration unit according to claim 1 , wherein the filter element includes filter media.
5. The method of installing the filtration unit according to claim 1 , wherein the at least one opening includes a plurality of openings.
6. The method of installing the filtration unit according to claim 1 , wherein the filtration unit includes a plurality of filter elements.
