Abstract

Die Erfindung betrifft einen Abzug (10, 28, 32), insbesondere Laborabzug, zum Absaugen von gasförmigen Medien mit einer Einströmöffnung (18) zum Einsaugen von Luft. Um die Auswirkungen von für das Abzugsverhalten störenden Strömungen zu reduzieren, ist der Abzug (10, 28, 32) dadurch gekennzeichnet, dass mindestens eine Ausströmeinrichtung (19, 29, 33) zum Erzeugen einer sich in einen Umgebungsraum erstreckenden Luftbarriere vorgesehen ist, wobei die Luftbarriere zum Umlenken von störenden Raumluft- und/oder Zuluftströmungen in Richtung des Umgebungsraumes und von der Einströmöffnung (18) weg gerichtet ist.
