Abstract

A diffuser for use with a ventilating system comprising an apertured plate having means defining a surface extending inwardly from one edge of the or each aperture in the plate. Air passing through the aperture becomes entrained against the surface and then, by virtue of the coander effect remains entrained against the surface in which the diffuser is mounted.
