Abstract (en)
[origin: EP2246573A2] The device (11) has two connection flanges (15, 17) connected with each other by a pipe section defining a passageway (21). A third connection flange (20) is provided between the first and second connection flanges in the passageway. Baffle plates (23) are arranged at a certain distance from each other. The baffle plates are arranged in an expanded cross-sectional area (33) of the pipe section, and are arranged at a distance from the third connection flange. The cross-sectional area is provided with the pipe section for receiving the baffle plates. An independent claim is also included for a method for protecting a high vacuum pump from condensable vapors.
