The COMPAIR STEEL flow^® system, which is available in the usual 150 mm dimensions as a flat duct and round duct, meets the highest requirements for tightness by means of all-round lip seals which are firmly integrated into the system components.

Made of galvanised sheet steel, COMPAIR STEEL flow^® is particularly hard-wearing. The flat duct with its variably integrated centre bar has a permissible point loading of 100 kilograms. This makes new, very exciting installation options possible. For example, laying in floor structures made of concrete or wet screed. For multi-storey houses, the exhaust duct can be laid, for example, in the floor structure of the storey above. For downdraft systems in cooking islands too, technically and design-optimised exhaust air solutions present themselves, as the duct can be laid invisibly in the floor. Of course, all the conventional routing options are also possible: hidden on the kitchen elements, in the base area and in suspended ceilings, or as an open solution in industrial design.

COMPAIR STEEL flow^® delivers the same perfect flow results as Naber’s proven COMPAIR^® flow and COMPAIR^® bion. Guide elements integrated into the round bends ensure aerodynamically optimal flow and pressure losses that are 80 percent lower than with standard ducts.
