FAN COMPRISING ANTI-DEFLAGRATION HOUSING

The fan comprises a first electromechanical module including a wheel supported by a shaft coupled to a driving motor, a second mechanical module including a body delimiting a space for receiving the first electromechanical module in which the wheel and the driving motor are received, and a third electronic module including a plurality of electronic components. The third electronic module includes a housing in which the plurality of electronic components is housed, the housing also comprising a deflagration protection exhaust comprising an upper wall and two inclined walls extending on either side of the upper wall so as to form a space extending substantially axially between the upper surface of the housing and the upper wall in order to allow the discharge of overpressures in case of deflagration.
