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).
A modular air vent assembly comprising a rectangular frame having four closed sides, the frame being divided into a plurality of individual square sections by dividing plates located along the length of the assembly to separate the air flow of each section from its adjacent section and each section being provided with a separate air damper means for controlling air flow through each section independently of the other sections and a grill removably supported at the top of the respective section of the vent assembly, the vent assembly including support means adapted to rest on a supporting surface of a raised floor assembly, and each grill including louvres angled to direct air flow therethrough to one side and the grill being locatable in one of a plurality of orientations such that air flow can be directed in any one of a plurality of directions relative to the vent assembly, each direction corresponding to a respective orientation of the grill.
