This design uses a deviating installation feature: the vent has to be built in.
A stainless steel housing which holds the lames, disappears into the wall and becomes finalized by a square front.
This results in a minimal exposure onto the wall. From a side view the vent will be nearly noticeable.
Two horizontal lames will open and close by air pressure.
An ecological insulated butterfly damper is integrated.
Dripping stripes on the building’s wall are avoided by an effective drip catcher below.
Finishing: brushed stainless steel, white and black grey.
The stainless steel can be recycled at the end of its life circle.
