Having described at least one preferred embodiment of the invention, what is claimed is: 1. A particulate filtration system for removing particulates suspended in a fluid, the system comprising: a filter element having a first end and a second end; and a pre-collector body component operably connected to the filter element and capable of receiving an electrical charge to attract and remove particles suspended in the fluid, said pre-collector body component comprising a substantially continuous sidewall surface, an open first end, and a closed second end, said open first end of said pre-collector body component connected to said second end of said filter element. 2. The system of claim 1 further including a discharge electrode spaced apart from the body component, the discharge electrode capable of receiving an electrical charge causing a difference in the electronic potential between the body component and the discharge electrode. 3. The system of claim 2 wherein the difference in the electric potential between the body component and the discharge electrode is at least 20,000 volts. 4. The system of claim 1 wherein the end of the pre-collector body component is operably connected to the second end of the filter element by a threaded connection. 5. The system of claim 1 wherein the pre-collector body component is made substantially of metal. 6. The system of claim 1 wherein the pre-collector body component comprises a cylindrical tube having a substantially continuous sidewall surface, an open first end, and a closed second end. 7. The system of claim 6 wherein the cylindrical tube includes a number of apertures extending through the tube's sidewall surface. 8. The system of claim 1 wherein the pre-collector body component is positioned upstream of the filter element. 9. The system of claim 1 wherein the pre-collector body component is positioned coaxially of the filter element portion. 10. A filter assembly for use in a particulate filtration system, the system including a housing divided into a first plenum and a second plenum by a tube sheet with the first plenum in fluid communication with an inlet and the second plenum in fluid communication with an outlet, the tube sheet defining an aperture extending between the first plenum and the second plenum, the system further including a discharge electrode coupled to a first electric potential, the filter assembly comprising: a support frame having a first end that is adapted to couple to the tube sheet at an aperture and a second end; a filter media positioned around the periphery of the support frame; and a pre-collector body component comprising a substantially continuous sidewall surface, an open first end, and a closed second end, said pre-collector body component open first end coupled to the second end of the support frame, the pre-collector body component being electrically coupled to a second electric potential; wherein the difference in the first electric potential and the second electric potential is operable to cause at least a portion of the particulates in the first plenum to collect on the pre-collector body component. 11. The filter assembly of claim 10 wherein the pre-collector body component is made substantially of metal. 12. The filter assembly of claim 10 wherein the pre-collector body component includes a cylindrical tube having a substantially continuous sidewall surface, an open first end, and a closed second end. 13. The filter assembly of claim 12 wherein the cylindrical tube includes a number of apertures extending through the tube's sidewall surface. 14. The filter assembly of claim 10 wherein the pre-collector body component is positioned upstream of the filter element. 15. The filter assembly of claim 10 wherein the pre-collector body component is positioned substantially coaxially with the support frame. 16. The filter assembly of claim 10 wherein the difference in the first electric potential and the second electric potential is at least 20,000 volts. 17. A method for removing particulates suspended in a fluid flowing through a housing, the housing divided into a first plenum and a second plenum by a tube sheet, the first plenum in fluid communication with an inlet, the second plenum in fluid communication with an outlet, the tube sheet defining an aperture extending between the first plenum and the second plenum, the method comprising: providing a filter element having a first end and a second end, the first end sealingly coupled to the tube sheet and adjacent the aperture, the filter element extending from the tube sheet into the first plenum; providing a pre-collector body component located upstream of the filter element, the pre-collector body component comprising a substantially continuous sidewall surface, an open first end, and a closed second end; connecting the pre-collector body component open first end to the second end of the filter element; providing a discharge electrode; coupling the pre-collector body component to a first electric potential and the discharge electrode to a second electric potential wherein the first electric potential and the second electric potential are different so that at least a portion of the particles suspended in the fluid moving between the pre-collector body component and discharge electrode are attracted to one of the pre-collector body component or discharge electrode and any remaining particles are removed from the fluid as the fluid passes through the filter element. 18. The method of claim 17 wherein the first electric potential is ground and the second electronic potential is between negative 20,000 volts and negative 50,000 volts DC.
