The BORA principle
We don’t even let cooking vapours and smells rise as we draw them away where they are created: directly at the cooktop, directly from the saucepan, roaster, frying pan or grill. This has nothing to do with magic, just with applied physics according to the basic principle of fluid dynamics. We simply use a cross flow that is larger than the rising speed of the cooking vapour.
Cooking vapours rise at a maximum of one metre per second.
The BORA cooktop extractor draws off the vapour in a downward direction at about four metres per second.
The higher lateral flow removes cooking vapours and smells effectively and directly at the cooktop.
