A filter tube frame for use with a filter bag house. The filter tube frame includes an end cap having a pivotable handle attached thereto to facilitate removal of the tube frame from the bag house. The handle includes a lever surface adapted to engage a tube sheet surface, thus, during use, providing a force to urge the end cap away from the tube sheet and unseat the filter tube frame from the tube sheet.

I claim: 1. A filter tube frame comprising: (a) a first end and a second opposite end; (b) an end cap at the first end, the end cap having a body with a top surface, a periphery, and a lower edge; (c) a handle pivotably mounted to the end cap, the handle having a body and a first end and a second end, the handle movable from a first position to a second position; and (d) a first pivot point located on the handle between the body and the first end and a second pivot point located on the handle between the body and the second end; wherein the handle, when in the first position, has at least a portion of the handle body and the first end and the second end positioned between the top surface and the lower edge, and, the handle, when in the second position, has the handle body above the top surface of the end cap and the handle first end and the handle second end below the lower edge of the end cap. 2. The filter tube frame according to claim 1, wherein the first end has a lever surface. 3. The filter tube frame according to claim 2, wherein the lever surface includes a radius portion. 4. The filter tube frame according to claim 2 wherein the second end has a lever surface. 5. The filter tube frame according to claim 1, wherein the handle is pivotally mounted to the end cap at the first pivot point proximate the first end and at the second pivot point proximate the second end. 6. The filter tube frame according to claim 1, wherein the handle, when in the first position, extends from the periphery of the end cap at least 0.25 inch. 7. The filter tube frame according to claim 6. wherein the handle, when in the first position, extends from the periphery of the end cap at least 0.5 inch. 8. The filter tube frame according to claim 1, wherein a distance between the first pivot point and the first end of the handle is at least 0.5 inch. 9. The filter tube frame according to claim 8, wherein a distance between the first pivot point and the first end of the handle is about 0.8 inch. 10. The filter tube frame according to claim 1, further comprising a cage extending from the end cap to the second end of the filter tube frame. 11. A filter tube frame end cap, the end cap comprising: (a) a flange having an outer periphery and an inner rim, the inner rim defining an air flow path; (b) a handle pivotally attached to the outer periphery at a first pivot point and at a second pivot point, the handle having a length between the pivot points at least one-half of the flange periphery; and (c) the handle having a first distal end extending past the first pivot point at least 0.25 inch and a second distal end extending past the second pivot point. 12. The end cap according to claim 11, wherein each of the first distal end and the second distal end has a radiused lever surface. 13. The end cap according to claim 11, wherein the second distal end extends past the second pivot point at least 0.25 inch. 14. The end cap according to claim 13, wherein each of the first distal end and the second distal end has a radius cam surface. 15. A method of removing a filter tube frame from a tube sheet, the filter tube frame being held within the tube sheet with a compressive force, the method comprising: (a) grasping a handle body, the handle body being pivotally attached to the filter tube frame; (b) pivoting the handle body away from the tube sheet and pivoting a distal end of the handle toward the tube sheet; (c) contacting the tube sheet with the distal end of the handle; and (d) after contacting, releasing the compressive force holding the filter tube frame, and extracting the filter tube frame from the tube sheet. 16. The method according to claim 15, wherein the step of pivoting the handle body away from the tube sheet and pivoting a distal end of the handle toward the tube sheet comprises: (a) pivoting the handle body away from the tube sheet and pivoting a first distal end and a second distal end of the handle toward the tube sheet. 17. The method according to claim 16, wherein the step of contacting the tube sheet with the distal end comprises: (a) contacting the tube sheet with the first distal end and the second distal end.
