Which operating mode is the right choice for you depends on various factors. Exhaust air: in extraction mode, the countertop extractor draws in vapours and removes grease particles with the help of the grease filter. The filtered air is then transported out of the kitchen via a ducting system. Along with the filtered exhaust air, any excess moisture and odours are removed from the kitchen. Ducted recirculation: recirculation mode is energy-efficient. Recirculation mode filters out both grease and odours before feeding the cleaned air back into the room via a ducting system in the base unit. Plug&Play: easy planning and installation – Plug&Play installation returns the filtered air to the room via a discreet opening in the plinth, without the need for an additional ducting system. This involves much less planning and installation work.
