A mixer box for mixing two separate sources of air. Air from a first source is fed into a plurality of vented conduits. Each of the vented conduits has at least one vent opening, that allows the air from within the conduits to escape and enter a mixing chamber. Air from a second air source flows into the mixing chamber around the vented conduits. As the second air source flows around the vented conduits, turbulence is produced that mixes the second air source with the first air source escaping from the vented conduits. Flaps are used to control the flow of the first source of air out of the vented conduits and the flow of the second source of air around the vented conduits.
