Abrégé

The invention relates to an appliance for a double-flow ventilation device with modulated extraction, or blowing, of air, for an enclosure comprising two groups of at least one room, i.e. a first group and a second group, the appliance being characterised in that it comprises at least one sensor for determining blowing requirements of the first group, and a hub for managing a blowing, or extraction, flow from the second group, comprising at least one means for managing the blowing, or extraction, flow which is controllable according to the blowing requirements of the first group, and at least one sensor for detecting the pressure in the hub, the hub being built into the double-flow ventilation device in such a way as to receive the blowing, or extraction, flow.

Abrégé

The invention concerns a removable impeller (7) designed to be integrated in a fan (1), in particular for controlled mechanical ventilation, and configured in the shape of a wheel provided with a plurality of blades (8) and equipped with locking clips to enable its being fixed on a hub. The invention is characterized in that it includes projecting transmitting clips, arranged proximate a central neck having an axis of revolution that is parallel to that of the wheel, and designed so as to enable the locking clips to be alternately engaged or released. The invention also concerns a fan including such an impeller.
