Modular ceiling air diffusers are provided in which the core deflector elements are pre-fabricated in a one-hit one-part pressing operation to form a selected pattern of integral louvers shaped to deflect air in a desired horizontal air pattern. This reduces the labour content and material costs i n manufacturing modular ceiling air diffusers compared to prior art devices of this kind, without compromising the level of air distribution performance.</ SDOAB>
