<p>The air flow opening is used for supplying air into a working or dwelling area. Air is supplied independently of environment influences to room areas without restricting the freedom of movement and action of the user. The air flow opening has flexible closing ribs. The form of this system is determined by the pressure or by additional stiffening of the ribs. The air flow apertures within the system are smaller than one square millimetre. These apertures are formed by organic or inorganic fibres. The air flow regulator of this type is connected to air supply channel by a rigid nozzle. These outlt openings are arranged into a pattern of air supply channels so that all working places under channels are supplied with air.</p> |
