Intelmann® Flat Duct with Internal Reinforcement and Mounting Rail – for Ventilation and Exhaust SystemsThe Intelmann® Flat Duct with Internal Reinforcement and Mounting Rail is the particularly stable and durable solution for airflow management in ventilation, air conditioning, and exhaust systems. Its flat design with a 50 mm height makes it ideal for installations in ceilings, stud walls, or embedding in screed.Manufactured optionally from galvanised steel sheet with a zinc coating of 275 g/m² or stainless steel V2A (1.4301), the flat duct offers high corrosion resistance, stability, and longevity. The rectangular shape enables efficient airflow and optimal integration into modern ventilation systems.A key design feature is the integrated internal reinforcement, which provides increased shape stability and prevents deformation under load. Combined with the mounting rail, this results in a particularly secure and installation-friendly solution.The flat duct is therefore explicitly suitable for embedding in screed and reliably withstands the stresses from screed material and use. This makes it the ideal choice for floor-integrated ventilation systems.Additionally, the flat duct meets high fire protection requirements and is non-combustible according to DIN 4102, Class A1.Advantages at a glance:✅ Internal reinforcement – High shape stability and load capacity✅ With mounting rail – Easy and secure installation✅ Screed suitable – Ideal for low-level and integrated installations✅ Space-saving – Only 50 mm height✅ Robust design – Galvanised or stainless steel V2A✅ Efficient airflow – Rectangular duct geometry✅ Non-combustible – DIN 4102, Class A1✅ Versatile use – For residential, commercial, and industrial applicationsTechnical details:✔ Product name: Intelmann® Flat Duct with Internal Reinforcement and Mounting Rail✔ Width: 180 – 300 mm✔ Height: 50 mm✔ Length: 1000 mm✔ Material: Steel sheet, galvanised (275 g/m²) or stainless steel V2A (1.4301)✔ Internal dimensions: Dimensions refer to internal measurements✔ Fire protection: DIN 4102, Class A1Installation & application:Installation is carried out via the integrated mounting rail on walls, ceilings, or floor structures.
