dadurch gekennzeichnet, dass die Lüftereinheit eine Reihenanordnung oder eine Matrixandordnung von benachbart angeordneten Ionenlüftern umfasst, die über eine an die Ionenlüfter (2) angelegte Spannung einzeln gesteuert werden, so dass durch die Überlagerung der Einzelströmungen der Ionenlüfter (2) ein gewünschtes Strömungsprofil oder Strömungsfeld erzeugt wird. - Verfahren zum Führen von flachen Produkten (50), insbesondere von Bedruckstoffen, in Vervielfältigungsmaschinen, wobei die flachen Produkte (50) zumindest abschnittsweise durch einen Luftstrom (39a, 39b) geführt werden, der nach dem Verfahren nach Anspruch 12 erzeugt wird.
- Verfahren zum Ablegen von flachen Produkten (59), insbesondere von Bedruckstoffen, in Vervielfältigungsmaschinen, wobei das Ablegen der flachen Produkte (59) durch einen Luftstrom (62) zumindest unterstützt wird, der nach dem Verfahren nach Anspruch 12 erzeugt wird.
- Verfahren zum zonenweisen Pudern von Bedruckstoffen (50) in Vervielfältigungsmaschinen, wobei der Puder (72, 78) den Bedruckstoffen (50) durch einen Luftstrom (78) zugeführt wird, der nach dem Verfahren nach Anspruch 12 erzeugt wird.
