A fluid flow regulator 5 comprises a plurality of spaced flow directing members 11a-k each having a leading or upstream edge 15 and a trailing or downstream edge 17 in a flow direction F. The members are disposed in stepped relation, with adjacent members being displaced in the flow direction. The members may be blades and may be arranged in parallel. The upstream edge may be a single continuous edge, or may be a discontinuous edge which may be serrated. The members may have a first upstream section 21 terminating at the leading edge and a second downstream section 23 terminating at the trailing edge. The upstream section may be disposed substantially parallel to the flow direction and the downstream section may be inclined at a first angle α to the flow direction. The upstream edges may be located on a line inclined at a second angle ξ to a direction perpendicular to the flow direction or may be located on a curved line. The flow regulator may be an air flow discharge grille. A ventilation unit 3 comprising the regulator may be mounted to a ceiling (C, Fig.1), the regulator directing a discharged air flow towards the ceiling.
