Embodiment approach

[0199] The ventilator 200 includes a housing 202 that is generally volute-shaped. The housing preferably comprises two parts 202a, 202b which are connected, for example mechanically and / or by means of ultrasonic welding. The casing 202 constitutes a fixed portion of the fan 200 . The ventilator 200 also includes a rotating portion including at least one impeller and a shaft, which are driven by an electric motor 208 . In one implementation, the motor 208 may be a brushless DC motor. In the illustrated embodiment, the ventilator is of the single stage type, although it is obvious that the ventilator could comprise two or more stages. Figure 6 to Figure 9 The rotating part of the ventilator 200 is not shown. According to a preferred embodiment, however, the inventive impeller 300 constitutes the rotating part of the inventive ventilator 200 .

[0200] The ventilator includes an air inlet 204 and an air outlet 206, which are preferably tubular. The air inlet 204 is arranged...
