Title: Unitary air-diffusing wedge strip in air projection grille

Abstract: The present air diffuser has one or more unitary strips of adjoining tetrahedronal wedges which are progressively inclined and leaned laterally to deflect the supply air laterally outward beyond the diffuser for creating a wide, coherent, non-turbulent air blanket. At the outside of the diffuser, the wedge strip presents a series of adjoining triangular front faces which are imperforate to minimize air turbulence there when ambient room air is induced into the supply air stream emerging from the diffuser.
