Duct systems

Flexible and individual: the type of ventilation, the structural situation on-site, materials, design and much more – duct systems from Systemair adapt to requirements.

Circumstances alter, prerequisites do not remain the same, sudden changes represent new challenges – it's good that systems from Systemair can handle every situation. This applies to round and oval metal ducts, as well as our plastic pipe systems Systemair Tube F and ISO+. Hygiene is also an important consideration: the inside surfaces of the ducts are smooth, making them conducive to airflow and easy to clean.

Flow-related and acoustic considerations must be analysed before selecting a duct system. Furthermore, the routing of the ducts must be agreed with the other trades and adapted to the situation on the construction site early on. The next step: as soon as the volumes which need to be transported by the ventilation system are known, the ducts can be designed – calculating the quantity of air required according to DIN 1946-6. A maximum speed of 3 m/s is recommended in the main duct. This avoids high pressure losses and unnecessary noise.

But how can ventilation concepts be generated without a great deal of work? The answer: with Airplan from Systemair. Create ventilation concepts easily and in accordance with DIN 1946-6. Airplan comes up with suggestions for appropriate overall product solutions. • Safe and economical air distribution in the building
