The extractor device has a hood (1) incorporating at least two cross flow blowers (9), which are controlled/actuated individually. It also has a filter unit for at least partial cleaning of sucked-in air resp. exhaust gases, which are then returned as circulation air into the ambient air, or removed as waste air. The device also incorporates e.g. a halogen lamp. Hood and blowers are pivoted. The hood is of metal or a polymer, and is manufactured by deep-drawing, injection molding, folding, etc. |
