Abstract

The ventilator has a compartment (6) in which an electric motor (5) is placed, where the compartment includes an end wall (13) traversed by a shaft of the motor and supplied by pressurized air. Leakage collection chamber (7) intermediate between a volute (2) and the compartment is traversed by the shaft of the motor, where the chamber includes an exhaust outlet (20). The shaft of the motor includes a deflecting body (17) to separate the respective flows of air and oxygen and to orient the flows according to a direction perpendicular to the shaft.
