Air ducts
Air conditioning solutions are individual solutions. That is why we offer you our innovative air ducts, which we manufacture according to your project.
All air ducts from a single source
We manufacture folded ventilation ducts in all variants, as well as welded ducts and pipelines. Our product range also includes spiral ducts and fittings.
Energy saving and hygiene made easy
Our products comply with the current standards for air tightness and hygiene. We are also guided by the latest research findings.
Quality from Trier
All products are manufactured exclusively at our high-tech site in Trier. From there, delivery is made directly to the construction site.

MX smoke extraction ducts
Effective smoke extraction with smoke extractor MX
In a fire, there is not only an enormous potential danger in the fire, but also in the smoke. Many deaths occur as a result of heavy smoke development. In contrast to sprinkler systems, smoke extraction systems react directly to the smoke and thus considerably reduce the danger. In order to be able to offer you optimum quality in this area as well, we have expanded our product range with the MX smoke extraction system.
The smoke vent MX is a smoke extraction duct with CE certificate 0761-CPR-0513 according to EN 12101-7:2011. Product according to Building Rules List B Part 1 under Lfd. No. 1.17.6 of the German Institute for Building Technology (DIBt), edition 2015/1.
The test was carried out at room temperature with 1500 Pa negative pressure and at 600°C with 500 Pa negative pressure over a service life of 120 min. in accordance with DIN 18232-6 and prEN 1366-9. We also supply the corresponding fire gas expansion joints. The ducts are connected to the expansion joints using an SBM 30 frame profile.
