A dynamic seal is disclosed which prevents foreign material from entering the air bearing for a rotor apparatus. The rotor apparatus includes a housing, a generally cylindrical rotor disposed within the housing and having a shoulder, a fluid stream and a flexible seal plate with an inner wall forming a generally circular hole. The seal plate is secured to the housing with the seal plate inner wall normally abutting the shoulder of the rotor. In operation, the fluid stream is directed in the bearing space defined by the housing and exterior surface of the rotor and displaces the seal plate inner wall from the shoulder. A method for preventing foreign material from entering the bearing space defined by a housing and the exterior surface of a generally cylindrical rotor is also disclosed. The method comprises securing a flexible seal plate to the housing, with the seal plate having an inner wall forming a generally circular hole that normally abuts a shoulder portion of the rotor. The method further comprises directing a fluid stream in the bearing space, thereby displacing the seal plate inner wall from the shoulder.
