Intelmann aluminium flexible pipeFlexible pipe made of aluminium, for the highest requirements in accordance with DIN 24146The diameter specification refers to the inner diameter.Made in GermanyFlexible duct / air duct made of aluminiumNon-flammable according to DIN 4102 class A1Temperature resistance from -125°C to +250 °CMaterial thickness of 80 µm for 3 m (single layer)Material thickness of 2 x 50 µm for 5 m (double layer) Possible applications:Extractor bonnet / vapour extractionControlled domestic ventilationAir conditioning systemsExhaust airSupply airChimney supply airVentilation systemsAir treatment installationExtraction of vapoursGeneral air ducts The standard length of the ducts is 3 m (1-layer) compressed to 0.6 m or 5 m (2-layer) compressed to 1.2 m.

Increased material thickness (120 µm)The Intelmann FLEX is the further development of the well-known Intelmann aluminium flex pipe (F / FE). The Intelmann FLEX has the advantage that it is significantly more stable than the aluminium flex pipe (F / FE) and yet remains flexible. The Intelmann FLEX consists exclusively of coiled aluminium. The increased material thickness (120 µm) makes it less susceptible to damage and gives the pipe greater inherent rigidity.Intelmann FLEX guarantees a very high level of airtightness while retaining full flexibility.Intelmann FLEX is supplied compressed (approx. 1.2 m) and can be extended to its full application length (5 m).FEATURESNominal diameter [mm] Inside diameterPressure (max.)
