Fan hub

Ventilating fan

A fan () has a fan housing (). The latter has an air entrance opening () and an air exit opening (). It further has a swivel joint arrangement () having at least one swivel joint () that is arranged on a joint carrier (); at least one non-return flap () that is journaled rotatably by means of the at least one swivel joint () and, in its closed position, at least partly closes off the air exit opening (); and at least one elastic return member () that is associated with the at least one non-return flap () and urges it toward its closed position.

Ventilator

Cooling unit

A fan has a hub and a fan housing connected to the hub. The fan housing delimits an air passage of the fan outwardly. A fan wheel is connected to the hub and rotatably arranged in the air passage. A motor is arranged on the hub for driving the fan wheel. An electrical connection with at least one flexible line is connected to the motor and extends from the motor to the fan housing. A recess is provided within the fan housing and the flexible line extends from the motor to the recess. A holding member locks in place in the recess and deflects the flexible line at least at one deflection location about a predetermined minimum angle to thereby effect strain relief on the portion of the flexible line extending from the deflection location to the motor.
