An air diffuser comprises a body 1 mounted in the angle between a floor 2 and wall 3, and having an outlet 4 and a double-curved inner surface to deflect air issuing from a duct 5, and to reduce the noise level. The diffuser may be constructed for installation in a corner of the room and may comprise a body of different thicknesses which defines an equivalent inner surface to that of the body 1 shown. The areas of the outlet 4 and duct 5 may be equal. A member 6 retains the body 1 in position. |
