The Bora cooktop extractor fan is more effective than conventional extractor hoods and draws off cooking vapours right where they arise: at the cooktop itself. The ventilation technology employs a simple basic principle of physics: Vapour rises at a speed of one metre per second, but this cooktop extractor fan draws off the vapour in downward direction at 4 metres per second. The patented cooktop extractor fan requires little space, is installed between the hobs and fits elegantly.
