For producing sparkling water at home: the AARKE CARBONATOR PRO. What makes it different from the standard version? It is the beautifully designed glass bottle that makes the PRO version special. Handling the water bubbler is child's play with both versions. And in the PRO version, it's the glass bottle that, filled with cold tap water, is screwed into the machine's receptacle and filled with gas from the cartridge seated in the housing with a flick of the lever. In this case, during the filling process, for safety reasons, a housing made of sheet steel lowers around the glass bottle to be filled. All this functions in an uncomplicated way and can be operated with one hand. The scope of delivery includes a glass bottle with a usable volume of 700 ml and stainless steel screw cap.
