ABSTRACT:
A central air uptake attachment has a housing with upper and lower outlets. The housing is juxtaposable to a room wall air outlet communicating with the ducts of a central air conditioning system. With the room wall, the housing defines an internal chamber for channeling air from the room wall air outlet to the upper or lower outlet. The central air uptake attachment is constructed to be conveniently packaged and transported and readily attached to the room wall.
