Title (EN) FUME EXTRACTION DEVICE
(FR) DISPOSITIF D'EXTRACTION
(DE) ABZUGSVORRICHTUNG
Abstract:
(EN) Fume extraction device, in particular laboratory fume extraction device, comprising a housing (11) with an operating chamber (12) that is accessible to an operator (B) through an operating hole (19) in the housing (11); the operating chamber (12) is defined by a base (15), side walls (14, 17) and a cover (16); the operating hole (19) and/or at least one fresh air supply hole (30) in the area of the operating hole (19) is/are provided for allowing fresh air (Z) to flow into the operating chamber (12), and at least one waste air hole (34) in the area of the cover (16) is provided for allowing waste air (A) to escape. At least one filter holder (43, 44) for accommodating at least one filter element (41, 42) is placed upstream of the at least one waste air hole (34); the at least one filter holder (43, 44) is accessible through the operating hole (19) such that the filter element (41, 42) is accessible and replaceable from the operating chamber (12).
(FR) L'invention concerne un dispositif d'extraction, en particulier un dispositif d'extraction de laboratoire, qui présente une enceinte (11) présentant une chambre de travail (12) qui est accessible via une ouverture de travail (19) de l'enceinte (11) par un utilisateur (B), la chambre de travail (12) étant délimitée par une paroi de fond (15), des parois latérales (14, 17) et une paroi de recouvrement (16), l'ouverture de travail (19) et/ou au moins une ouverture d'aération (30) au niveau de l'ouverture de travail (19) pour l'entrée d'air d'aération (Z) étant situées dans la chambre de travail (12) et au moins une ouverture d'évacuation d'air (34) étant située au niveau de la paroi de recouvrement (16) pour l'évacuation de l'air résiduaire. Au moins un logement (43, 44) de filtre, destiné à recevoir au moins un élément (41, 42) de filtre, est disposé en amont de ladite au moins une ouverture d'évacuation d'air (34), ledit au moins un logement (43, 44) de filtre étant accessible à travers l'ouverture de travail (19) de telle sorte que l'élément (41, 42) de filtre est accessible et peut être remplacé à partir de la chambre de travail (12).
(DE) Abzugsvorrichtung, insbesondere Laborabzugsvorrichtung, die ein Gehäuse (11) mit einer Arbeitskammer (12) aufweist, die durch eine Arbeitsöffnung (19) des Gehäuses (11) für einen Bediener (B) zugänglich ist, wobei die Arbeitskammer (12) durch eine Bodenwand (15), Seitenwände (14, 17) und eine Deckwand (16) begrenzt ist, wobei die Arbeitsöffnung (19) und/oder mindestens eine Zuluftöffnung (30) im Bereich der Arbeitsöffnung (19) zum Einströmen von Zuluft (Z) in die Arbeitskammer (12) und mindestens eine Abluftöffnung (34) im Bereich der Deckwand (16) zum Ausströmen von Abluft (A) vorgesehen sind. Vor der mindestens einen Abluftöffnung (34) ist mindestens eine Filteraufnahme (43, 44) zur Aufnahme mindestens eines Filterelements (41, 42) angeordnet ist, wobei die mindestens eine Filteraufnahme (43, 44) durch die Arbeitsöffnung (19) hindurch zugänglich ist, sodass das Filterelement (41, 42) von der Arbeitskammer (12) her zugänglich und auswechselbar ist.
