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 .
