Excellent performance thanks to optimal ducting and installation.
Intelligently selecting and installing the duct system not only has a very positive effect on the output of the ventilation system; it also minimises the noise gene rated.
It is therefore decisive for the efficiency of the entire ventilation system.
The duct type.
In Gaggenau’s accessories catalogue, customers can select the type of duct appropriate to their needs, whether aluflex pipe, round duct or a flat duct system. Depending on
the duct type, they can choose from the nominal sizes DN 150 and DN 200. For maximum output with minimal noise, the diameter should always be as large as possible.
For straight ducting, the use of plastic or metal ducts with smooth, level inner surfaces is recommended. These enable a laminar flow of air during extraction, without air
turbulence. For sections that are not straight and for bends, aluflex pipe are preferred because they make it possible to avoid hard edges.
Where space limitations are a concern, the first choice is the Gaggenau flat duct system. The remarkable design with special conducting fins in the bends and junction pieces
allow for a very low hight and large nominal size, thus ensuring very efficient air circulation. This also applies in situations where there are many bends. We strongly discourage
the use of other flat ducts due to the high output losses in duct bends, duct corners and junction pieces.
Spiral and corrugated ducts should definitely not be used. In addition to displaying the worst flow conditions, these types also tend to flutter and thus generate noise.
The duct diameter.
A good guideline here is: The duct diameter should be as large and constant as possible, while the ducting should be as short and straight as possible. The wall outlet must
correspond to the duct diameter.
The building regulations.
Please observe the local applicable building regulation when configurating ventilation solutions.
The plastic flat duct complies with the Needle Flame Test (according to IEC 60695-5-11), the V2 flammability class (according to UL94) and the B1 building material class (DIN 4102-1).
The metal ducts are particularly suitable for Vario downdraft and Table ventilation in countries with increased fire protection requirements.
The metal ducts are non-combustible and suitable for all combinations.
