A ventilation system contains different components:
Outlets and intakes for air
These components can be altered to suit the interior architecture by using different material or by wraping for example with semi translucent material.
Here you will see some possibilities, a complete list is of course impossible.
Outlets and intakes for air:
The clean room ventilation technic brought up the textile ventilation pipe. Due to the huge surface it is designed excelent to bring in big volume streams of air into the room without any draft.
There are not just different colors of the textile to match the interior, but also it is possible to give it a special cut to for example design a ventilating sculpture.
There are two possibilitys. Either the pipe is covered or wraped with a suiting material
or it is manufactured of a material that matches the room by itself.
The pipe cover for example could be made of semi translucent polypropylene. It is mounted below the pipe. It can also be lighted for aditional accentuation.
Anyway the pipe can also be made of different material. Steel can be replaced by flexible aluminum pipe, stainless steel or plastic pipes in different designs.
There are available several covers or wraps for this unit and as well for the ventilation unit that inludes heat exchanger, ventilators, silencers and filters:
You see, there are a lot of possibilities - enough ways to play around.
