Sealing and purging arrangement for a main bearing region

Apparatus for sealing and purging a bearing region includes a bearing housing (16) having at least one hole (42, 44) that allows a flow of air to flow through the at least one hole (42, 44), and at least one bearing seal (18) that allows the flow of air to flow through the at least one bearing seal (18), thereby creating a pressure difference across the bearing seal (18). The apparatus also includes an air directional device (46) having at least a portion of the flow of air to flow adjacent to the air directional device (46), and a pair of components having a gap (32) between the pair of components that allows the at least a portion of the flow of air to flow through the gap (32), thereby purging the gap (32).
