The Bora principle: the innovation behind the idea

* Bora.jpgThe original Bora cooktop extractor is more effective than conventional extractor hoods - but why? Bora stops cooking vapours and odours from rising in the first place by extracting them from the place they are created.

The concept is based on applied physics and the basic principles of fluid mechanics: the lateral flow is greater than the rising speed of the cooking vapour from pots and pans. From a purely physical perspective, it is therefore easier to directly extract the vapour at the cooktop.

Steam and odours rise at a maximum speed of one metre per second. However, the Bora cooktop extractor instantly draws these off in a downward direction at approximately four metres per second. The result: vapours are fully extracted and odour and grease particles are unable to spread around the room, settle on unit surfaces or penetrate materials. Instead of spreading around the room, grease particles released while cooking are trapped in the stainless-steel grease filter.

Original Bora cooktop extractors offer impressive advantages over conventional extractor hoods: they use far less energy and extract less of the expensively heated ambient air as the extraction concept is based on flow speed rather than air volume. They work more effectively as the vapour above the cooktop is unable to escape into the air as freely as with an extractor hood. The powerful yet energy-efficient motor uses less electricity and runs far more quietly.
