Helical Duct

The round duct offers an optimal solution for most air conditioning, ventilation and extraction systems.

Due to its smaller friction surface it offers a lower pressure loss and allows a minimum noise level by eliminating dead angles and turbulence areas, thus reducing the consumption of the ventilation units.

The pipes and accessories are manufactured in top-quality galvanised steel, with a Z-275 zinc coating and thickness ranging between 0.6, 0.8, 1 and 1.2 mm depending on the diameter, achieving optimum rigidity and resistance to deformation in accordance with the UNE-EN 100.102.88 standard.

Diameters ranging from 80 to 1,500 in helical or smooth format, with a standard length of 3 metres. There is also the option of manufacturing customised lengths as well as a wide range of standard accessories available and even special pieces and custom-made support elements.
