The Ventmann CIRCLE COANDA Vent air diffuser has a patented plaster-based design that allows it to integrate seamlessly into walls and ceilings. The air diffuser can be plastered and painted in a desired colour to match the ceiling or interior design. Plaster is also a natural, non-toxic material with a low carbon footprint and is thus comparatively environmentally friendly. The air diffuser makes use of the Coanda effect and diffuses the air parallel to the ceiling. This was an important point for the jury, as it is much more pleasant for people who are in a room if the air is not channelled directly at them.
