ABSTRACT An improved air vent (10) comprises a frame mounted from folded sheet metal, incorporating air dampers (23,24) in the bottom thereof and a plurality of square grills (21) located on supports (18,20) at the upper extremities of the frame. The frame includes four walls (11,12,13 & 14) which form a housing, and this housing is divided by barriers (16,17) into a number of chambers through which air passes. Each chamber has a grill (21) covering its upper opening and a pair of dampers (23,24) which adjustably control air flow through the chamber. Each grill 21 has a plurality of angled louvres 22 which divert the air to one side as it passes through the grill and the direction (A) in which the air is diverted is altered by rotating the grill within the housing. In this way different grills within the assembly may divert air flow through each grille (21) is adjusted by its respective dampers (23,24).
