A device (100) for treating the air in a confined space, comprising a first module (1) and a second module (2) that are telescopically coupled, in such a way that the two modules (1, 2) can slide one respect to the other in order to adjust to a different thickness of a wall that separates the inside from the outside. The device (100) comprises a heat exchanger (3) disposed in the first module, a first fan (V1) disposed in the first module downstream a filter (Z) to extract air from the outside to the inside, and a second fan (V2) disposed in the second module to extract air from the inside to the outside. The device (100) also comprises a radon detector (R) connected to a control unit (7) that controls the two fans. |
