In a sterilizing oven filtered air is circulated by a circulator situated within the oven and driven by an electric motor through a shaft, said motor being situated outside the oven. Since the air within the sterilizing oven must have a very low content of particles compared to common atmospheric air, it must not be possible for air to penetrate from the outside through the extension of the shaft. The shaft is therefore received in two spring-loaded gaskets in a sealing chamber which is supplied with filtered air at a low overpressure through a connection to a pump. |
