摘要

The ventilation system (1), especially for vehicles and machinery cabins, has a swing blower fan (5). A pliable and shock absorbent coupling (8,10,13) is between the swing drive (7) and the swing fan. The coupling is an intermediate gearing (7-9) or a belt transmission with elastic belts and a toothed belt. The drive is an electromotor or a pneumatic and/or hydraulic drive.
