Abstract

A set of parts for a radial fan has a fan wheel (2), a main housing part (1), and a complementary housing part (3). They can be assembled to form a first housing that encloses the fan wheel (2). The housing has an inlet opening (27) and an outlet (23). At least one second complementary fan wheels (2′, 2″) (3′, 3″), the shape of which differs from the first fan wheel part (2), can be connected to the motor instead of the fan wheel (2).
