Zusammenfassung:	A rotary machine (10) includes a machine rotor (12), a bearing (15) coupled to the machine rotor (12), a machine stator (14), and a sealing device (16) disposed between the machine rotor (12) and the machine stator (14). The sealing device (16) includes a dry gas seal (18, 20) and first and second seals (26, 42) disposed between the dry gas seal (18, 20) and the bearing (15). One or both of the first and second seals (26, 42) includes a brush seal or more specifically a brush seal including a plurality of non-metallic fibers (28).
