Those three things are functioning as a ventilation hood. It's a really neat idea. Each of those three towers, for lack of a better term, is 560mm tall and 180mm wide, is attached to the counter, rotates 270 degrees, and uses a remote blower to do the actual ventilating.
What I'm showing you here is the Alia from Homeier and it represents something really new in ventilation. The Alia towers can be combined in groups of two, three, four or five, depending on the need. Kitchen pros, here's the spec sheet.
I can see using these on an island as an alternative to dropping a hood from the ceiling. Their height would make them more effective than a pop up extractor and that the individual units rotate just adds to that effectiveness. Great idea Homeier. What do you guys think?
