Beschreibung
Zusammenfassung:	The ventilator has housing (1), impeller (2), drive motor (5) and backrest (3). The housing is provided with inlet nozzle (1-1), cylindrical flow guide (1-2), connector (1-4), diffuser (1-5) and guide vane wing (1-3), so as to secure backrest and for fastening the housing on a dedicated unit or building. The impeller is rotatably mounted about a central axis and is provided with central hub with vanes which are provided in region of radial outer edge with flow elements. The drive motor is designed either as three-phase asynchronous motor or as an electronically commutated DC motor.
