Abstract

A V-shaped filter includes a pair of filter media panel elements having respective root ends and diverging therefrom to distal ends in a V-shape. A single unitarily molded fixture is provided, securing the pair of filter media panel elements in the V-shape.

First claim

What is claimed is:

1. A V-shaped filter for filtering fluid, comprising a pair of filter media panel elements having respective facing root ends and diverging therefrom to distal ends in a V-shape, and a single unitarily molded fixture securing said pair of filter media panel elements in said V-shape,
wherein said fixture lies in a coordinate system having X, Y and Z axes orthogonal to each other, said fixture has a base portion at said distal ends of said filter media panel elements, said base portion having a central opening passing fluid therethrough, said fixture has a pair of endwall portions spaced from each other along the Y-direction, each said endwall portion extending in the Z-direction from said base portion, each said endwall portion lying in an X-Z plane, a first of said filter media panel elements lying in a first oblique plane oblique to each of an X-Y plane and a Y-Z plane, a second of said filter media panel elements lying in a second oblique plane oblique to each of the X-Y and Y-Z planes, said first and second oblique planes intersecting at an intersection line extending in the Y-direction, said fixture has a first lattice-work portion through which fluid flows, said first lattice-work portion lying in said first oblique plane and extending from said base portion towards said intersection line, said fixture has a second lattice-work portion through which fluid flows, said second lattice-work portion lying in said second oblique plane and extending from said base portion towards said intersection line.

2. The V-shaped filter of claim 1 , wherein the fluid passes through the central opening in the Z-direction.

3. The V-shaped filter according to claim 1 wherein said fixture is a one-piece integral member.

4. The V-shaped filter according to claim 1 wherein said first and second lattice-work portions are spaced from each other by a gap having a width spanning along the X-direction, the gap width varying from a maximum at said base portion and narrowing to lesser widths as the gap extends away from said base portion.

5. The V-shaped filter according to claim 4 wherein said first and second lattice-work portions have respective inner faces facing each other across said gap, and have respective oppositely facing outer faces facing away from said gap, one of said inner and outer faces supporting a respective said filter media panel element.

6. The V-shaped filter according to claim 5 wherein said first and second endwall portions have outer edges extending beyond the respective filter media panel element to provide an outer profile encompassing said pair of filter media panel elements recessed inwardly of said outer edges, to protect said pair of filter media panel elements including during installation, removal, and cleaning thereof.

7. The V-shaped filter according to claim 5 wherein:
said first filter media panel element has a first border engaging said first endwall portion, and a second border engaging said second endwall portion;
said second filter media panel element has a first border engaging said first endwall portion, and a second border engaging said second endwall portion;
said first endwall portion has a first section at said first border of said first filter media panel element, a second section spanning said gap, and a third section at said first border of said second filter media panel element;
said second endwall portion has a first section at said second border of said first filter media panel element, a second section spanning said gap, and a third section at said second border of said second filter media panel element.

8. The V-shaped filter according to claim 7 wherein:
said fixture has:
a first adhesive engagement surface extending along said first section of said first endwall portion;
a second adhesive engagement surface extending along said first section of said second endwall portion;
a third adhesive engagement surface extending along said third section of said first endwall portion;

a fourth adhesive engagement surface extending along said third section of said second endwall portion.

9. The V-shaped filter according to claim 7 wherein:
said first section of said first endwall portion has a rhomboid shape;
said second section of said first endwall portion has a triangular shape;
said third section of said first endwall portion has a rhomboid shape;
said first section of said second endwall portion has a rhomboid shape;
said second section of said second endwall portion has a triangular shape;
said third section of said second endwall portion has a rhomboid shape.

10. The V-shaped filter according to claim 9 wherein:
said first endwall portion, including said first, second, and third sections thereof in combination, has a trapezoidal shape with exactly one pair of parallel sides;
said second endwall portion, including said first, second, and third sections thereof in combination, has a trapezoidal shape with exactly one pair of parallel sides.

11. The V-shaped filter according to claim 10 wherein:
said first endwall portion, including said first, second, and third sections thereof in combination, has a frusto-triangular shape;
said second endwall portion, including said first, second, and third sections thereof in combination, has a frusto-triangular shape.

12. The V-shaped filter according to claim 1 wherein:
said first endwall portion has a first handle extending outwardly therefrom oppositely from said gap;
said second endwall portion has a second handle extending outwardly therefrom oppositely from said gap.

13. The V-shaped filter according to claim 12 wherein:
said first handle extends from said first endwall portion in a first Y-direction;
said second handle extends from said second endwall portion in a second opposite Y-direction.

14. The V-shaped filter according to claim 1 wherein:
said fixture and said pair of filter media panel elements are housed in a housing having a service door;
at least one of said base portion of said fixture, said housing, and said service door has one or more ramped interface surfaces forcing pressed sealing engagement of said fixture in said housing.

15. A fixture for a V-shaped filter for filtering fluid, said V-shaped filter having a pair of filter media panel elements having respective facing root ends and diverging therefrom to distal ends in a V-shape, said fixture being a unitarily molded fixture securing said pair of filter media panel elements in said V-shape,
wherein said fixture is a one-piece integral member and lies in a coordinate system having X, Y and Z axes orthogonal to each other, said fixture has a base portion at said distal ends of said filter media panel elements, said base portion having a central opening passing fluid therethrough, said fixture has a pair of endwall portions spaced from each other along the Y-direction, each said endwall portion extending in the Z-direction from said base portion, each said endwall portion lying in an X-Z plane, a first of said filter media panel elements lying in a first oblique plane oblique to each of an X-Y plane and a Y-Z plane, a second of said filter media panel elements lying in a second oblique plane oblique to each of the X-Y and Y-Z planes, said first and second oblique planes intersecting at an intersection line extending in the Y-direction, said fixture has a first lattice-work portion through which fluid flows, said first lattice-work portion lying in said first oblique plane and extending from said base portion towards said intersection line, said fixture has a second lattice-work portion through which fluid flows, sai
