ABSTRACT:
An air supplying apparatus for supplying a clean room with air having a conditioned cleanliness, temperature and/or humidity includes an air control unit for discharging the controlled air, and an air outlet duct connected to an air outlet of the air control unit so as to receive the conditioned air from the air control unit through an opening which opens in a direction different from the direction of flow of air through the air control unit. The air outlet duct is formed from one or more perforated sheets having a multiplicity of air outlet apertures. The cross-sectional area of the air passage formed in the air outlet duct preferably progressively decreases towards the downstream end of the duct. A joint duct, which guides air in a direction different from the directions of flow of air through the air control unit and through the air outlet duct, may be connected between the air control unit and the air outlet duct.
