Abstract: A supply air apparatus for producing outdoor air into an indoor space assisted by an auxiliary powered blower by simultaneously mixing the outdoor air with air from the indoor space. In connection with an outdoor air flow way in a structure in a building between the indoor space and outside air, a flow space and flow connections for outdoor and indoor air for mixing with each other, the blower and a blow flow arrangement for leading a mixed flow of air into the indoor space in the building. In connection with a supply air device in an outer wall of the building, an air distribution device including: a frame; a flow space in the frame; an inflow outdoor and indoor air that joins with the flow space and opens into an internal space in the building; the blower; and a blow flow leading the mixed air into the indoor space.
