Abb· 1 ein Längsschnitt durch den Axiallüfter und Abt), 2 ein Querschnitt nach A-A der Abb. 1,Fig. 1 a longitudinal section through the axial fan and Abt), 2 a cross-section according to A-A of Fig. 1,

Der neue Axiallüfter besteht im wesentlichen aus dem lüftergehäuse 1 aus einem säurefesten Kunststoff, in dem axial der Motor 2 atageordnet ist, der in einem ebenfalls aus einem säurefesten Kunststoff bestehenden Gehäuse 3 gelagert ist· Dieses Motorgehäuse besitzt Torzugsweise einen doppelten Mantel 4, 5, von dem der innere Hantel 5 am vorderen Bnde mit einigen Durchloehungen 6 versehen ist, und es wird durch drei mit dem Liiftergehäuse 1 verbundene Stützrohre 7 gehalten· Auf der Motorwelle 8 sitzt das Schaufelrad 9» durch das die abzufordernden Gase oder Dämpfe angesaugt und weitergedrückt werden· Nach vom ist das Gehäuse durch eine halbkugelförmige Kappe 10 abgeschlossen, und hinter dem Elektromotor, also in der Strömung der Abgase, ist die den Motor umschliessende Ifcimantelung bei 11 düsenartig verjüngt, wodurch bei Betrieb im Motorgehäuse starker Unterdruck entsteht und durch die hohlen Motorstützen 7 kräftig Frischluft angesaugt wird. Mese Kühlluft strömt, von den Stützen 7 kommend, durch den Spalt zwischen den beiden Ummantelungen 4, 5 und tritt dann durch die Bohrungen 6 in den Motor und tritt durch die Verjüngung 11 wieder aus· Dieser ISihlluft-lSnlauf kann noch dadurch gesteigert werden, dass auf die hintere Motorwelle innerhalb dem Diffusor ein Propeller 12 aufgesetzt wird.The new axial fan essentially consists of the fan housing 1 made of an acid-resistant plastic, in which the motor 2 is axially arranged, which is also made of an acid-resistant plastic Plastic housing 3 is mounted.This motor housing has a double jacket 4, 5, of which the inner dumbbell 5 on the front volume with some perforations 6, and it is held by three support tubes 7 connected to the lifter housing 1 · On the motor shaft 8 sits the paddle wheel 9 »through which the gases or vapors to be extracted are sucked in and pushed further · to the the housing is closed by a hemispherical cap 10, and behind the electric motor, i.e. in the flow of the exhaust gases, the Ifci casing surrounding the motor is nozzle-like at 11 tapered, which creates a strong negative pressure in the engine housing during operation and strong fresh air through the hollow engine supports 7 is sucked in. Mese cooling air flows, coming from the supports 7, through the gap between the two casings 4, 5 and then enters the motor through the bores 6 and exits again through the taper 11 can be increased that a propeller 12 is placed on the rear motor shaft within the diffuser.
