Devices, systems and methods for a filter

1. A filter comprising:

a porous elongate body comprising metal fiber media, having a first end that is open, a second end that is closed, and a porous sidewall configured to filter fluids that flow through it;

a duct extending from the first end to the second end;

wherein the porous elongate body defines a flow path from the first end, into the duct, and across the porous sidewall; and

wherein the porous elongate body comprises a rolled sheet of metal fiber media overlapping itself, a first seam weld extending lengthwise along the rolled sheet of metal fiber media at the overlap, and a second weld extending lengthwise along the porous elongate body, wherein the second weld is substantially offset about 180 degrees from the first seam weld about a longitudinal axis extending along the porous elongate body.

2. The filter of claim 1 , further comprising a solid plate at the second end.

3. The filter of claim 2 , further comprising a ferrule connected about the first end of the porous elongate body.

4. The filter of claim 1 , wherein a flow of a fluid through the flow path across the porous sidewall comprises a pressure differential of less than about 10 pounds per square inch.

5. A filter system comprising:

a plurality of porous elongate bodies each comprising metal fiber media, each having a first end that is open, a second end that is closed, a duct extending from the first end to the

second end, and wherein the each porous elongate body defines a flow path from the first end, into the duct, and across a porous sidewall, and wherein each porous elongate body comprises a rolled sheet of metal fiber media forming the porous sidewall overlapping itself, a first seam weld extending lengthwise along the rolled sheet of metal fiber media at the overlap, and a second weld extending lengthwise along the porous elongate body, wherein the second weld is substantially offset about 180 degrees from the first seam weld about a longitudinal axis extending along the porous elongate body; and

a housing having an inlet and an outlet, disposed about the plurality of porous elongate bodies; and

wherein the plurality of porous elongate bodies are disposed within the housing in parallel such that each first end is oriented toward the inlet and each second end is oriented toward the outlet.

6. The filter system of claim 5 , wherein each of the plurality of porous elongate bodies further comprises a solid plate at the second end.

7. The filter system off claim 6 , wherein each of the solid plates are connected to an outlet brace of the housing.

8. The filter system of claim 5 , wherein each of the plurality of porous elongate bodies further comprises a ferrule connected about the first end.

9. The filter system of claim 8 , wherein each of the ferrules are connected to an inlet brace of the housing.

10. The filter system of claim 5 , wherein a flow of a fluid through the filter system from the inlet through the outlet comprises a flowrate greater than 500 standard liters per minute and a pressure differential of less than about 10 pounds per square inch.

11. A method of manufacturing a filter comprising:

rolling a first sheet into a first porous elongate body such that there is a portion of the sheet overlapping itself and wherein the portion is about an eighth of an inch in the circumferential direction of the rolled sheet;

seam welding the portion of the first porous elongate body to provide a first seam weld; and

welding along a length of the first porous elongate body along a longitudinal axis of the porous elongate body at a location substantially 180 degrees offset from the first seam weld, to form a second weld.

12. The method of claim 11 , further comprising seam welding a connector about a first end of the first porous elongate body.

13. The method of claim 11 , further comprising seam welding a solid plate at a second end of the first porous elongate body.

14. The method of claim 11 , further comprising disposing a second sheet about the first porous elongate body.
