<p>An exhaust line for removing gases communicates at a first end (9) with a vacuum source and at a second end provided with a suction opening. The exhaust line comprises at least two tube sections (1, 4, 6, 8) and a pivotal connection (3, 5, 7) arranged therebetween and interconnecting the interior of the tubes. The pivotal connection (3, 5, 7) is made of a polymer comprising an electrically conductive material and is in electrically conductive connection with the tubes (1, 4, 6, 8). At least the outer and inner surface of the tubes are electrically conductive and grounded.</p> |
