Abstract

A radial fan has a housing with a motor-drivable fan wheel. The fan wheel generates an air volume flow during operation. The housing has a blow-out portion (4) with an impeller (5). The impeller (5) has a plurality of impeller blades (7) spaced apart in the circumferential direction. The impeller (5) is driven by the air volume flow generated by the fan wheel.
