The invention relates to an airway for removing or supplying gaseous media such as solvent-containing air flows. The invention addresses the problem of improving an airway for removing or supplying gaseous media such as solvent-containing air flows in such a manner that same are gas and pressure-tight and corrosion-resistant against chemical, mechanical and abrasive influences, while simultaneously reducing the weight of the airways and the maintenance costs, improving and simplifying assembly, increasing the useful life and saving material and costs. This problem is solved in that: the walls (2.1, 2.2, 2.3, 2.4) are formed from a polypropylene sandwich panel (3) with fibreglass-reinforced outer and inner protective layers (4, 5), a honeycomb-structured core (6) and at least one profile body (8) which overlaps, on the airway outer side, the joints (7) of adjoining walls (2.1, 2.2, 2.3, 2.4), said joints being connected by adhesion and force-fitting using a first adhesive (KM1), and which profile body is held on the outer protective layers (4) by the adhesive (KM1) and additionally with fixing means (13) in a gas and pressure-tight manner; the arms (14.1, 15.1, 16.1, 17.1) of the connecting flange (14, 15, 16, 17) are fixed on the inner edges of the walls (2.1, 2.2, 2.3, 2.4) in a gas and pressure-tight manner by adhesion and force-fitting using the first adhesive (KM1) and fixing means (13); and the arm (14.2, 15.2, 16.2, 17.2) projecting perpendicular to the airway axis (K) is undetachably connected to the perpendicular projecting arm of the further airway (21) in order to form the gas- and pressure-tight coupling using a second adhesive (KM2) and screwing means (19) or said perpendicular projecting arms are detachably connected to one another using a sealing means (23) and screwing or catching means (19). |
