1. A method of separating debris from a pressurization air stream so as to supply cleaner pressurization air to a bearing compartment seal, the method comprising: directing the pressurization air stream around a baffle disposed upstream of the bearing compartment seal wherein the baffle is integral with a fan hub and rotates therewith and a capture annulus is a portion of a bearing compartment; andcapturing the debris in a cavity of a member disposed adjacent the baffle. 2. The method of claim 1 and further comprising rotating the baffle to induce rotation of the pressurization air stream. 3. The method of claim 1 and further comprising evacuating the debris from the cavity to a buffer air supply plenum. 4. The method of claim 3, wherein between about 15 and 50 channels are annularly arrayed along the member. 5. The method of claim 1, wherein the cavity extends into the member to a distance sufficient to allow the captured debris to be outside of a flow path of the cleaner pressurization air. 6. An assembly for separating debris from a pressurization air flow adjacent a bearing compartment seal in a fan section of an engine, the assembly comprising: a baffle positioned in the pressurization air flow upstream of the compartment seal; anda capture annulus disposed adjacent the baffle and having a cavity to collect the debris;wherein the baffle is integral with a shaft and rotates therewith and the capture annulus comprises a portion of a bearing compartment. 7. The assembly of claim 6 and further comprising channels that extend through the capture annulus to allow for evacuation of the debris from the cavity to a buffer air supply plenum. 8. The assembly of claim 7, wherein between about 15 and 50 channels are arrayed along the capture annulus. 9. The assembly of claim 6, wherein the baffle extends into the capture annulus to a distance sufficient to allow the captured debris to be substantially outside of a flow path of a debris free air stream. 10. The assembly of claim 6, wherein the baffle rotates with rotating turbomachinery within a gas turbine engine. 11. The assembly of claim 10, wherein the baffle centrifugally accelerates the pressurization air flow to induce rotation thereof. 12. The assembly of claim 6, wherein the baffle is configured to change a direction of flow of the pressurization air. 13. The assembly of claim 6, wherein the baffle is spaced downstream from an upstream edge of the capture annulus in a direction of the air flow, and wherein the baffle and the capture annulus face in opposite directions. 14. A gas turbine engine, comprising: a bearing compartment mounted within a fan section of the gas turbine engine, the bearing compartment including a bearing compartment seal that is operably supplied with a pressurization air flow;a shaft rotatably mounted within the gas turbine engine adjacent the bearing compartment, the shaft having a baffle positioned in the pressurization air flow upstream of the compartment seal; anda capture annulus disposed adjacent the baffle and having a cavity to collect debris. 15. The gas turbine engine of claim 14, wherein the capture annulus includes channels that extend therethrough to allow for evacuation of the debris from the cavity to a plenum. 16. The gas turbine engine of claim 14, wherein the baffle is integral with the shaft which comprises a fan hub and the capture annulus comprises a portion of the bearing compartment. 17. The gas turbine engine of claim 14, wherein the baffle extends into the capture annulus to a distance sufficient to allow the captured debris to be substantially outside of a flow path of a debris free air stream. 18.
