Abstract

A powered aspirator unit comprises an external shell (11) containing an electric motor (12, 13) on the shaft of which is keyed the suction fan (17). Between the motor and the fan there is a partition providing on a bottom face a fan containment cavity and on the other face is made the stator part (23) of a motor cooling impeller (24). In the partition (21) is made a seat (31) for a bearing (30) supporting the motor shaft (14). <IMAGE>
