Expertise from a single source. The Lipsheim site in the French Alsace region is where Gaggenau develops and produces its ventilation 400 series. The appliances are crafted to a large extent by hand and meet high quality standards. A wide variety of quality checks and measurements are also carried out by Gaggenau directly at the site. Challenging the established, breaking the mould, when and where this makes sense, in order to pave the way for new innovative ideas - this notion of the avant-garde is discernible with all our appliances. And it is the basis for our four main design principles that apply to all appliances: They are authentic, sculptural, present and generous.
