Abstract

The fan has an impeller (10) which has a blade ring (15) on its periphery. A partition (26) which is arranged on one of the side walls, engages with the impeller and divides its interior chamber into two chambers. The blade ring has labyrinth seal-type protrusions and/or cavities (20) directly on the peripheral wall region (19) of the blade ring for preventing the airflow between the impeller and the blade ring.
