  • Device for a suspended ceiling structure for rectangular filter elements
    Patent number: 4776263
    Abstract: A device for a suspended ceiling structure (1) for rectangular filter elements (2, 3). Some filter elements are located at a distance from each other to allow the suspension of light fittings from the suspended ceiling structure. An air stream is forced to flow out from the filter elements in the direction downwards towards the floor and vanes (8, 9) are then arranged substantially at the same level as and adjacent to at least one of those lateral surfaces of the fitting, which face the filter elements. The vanes are arranged at an angle to the air stream in such a way that the air is deflected and is made to flow towards a region (10) immediately below the light fitting.
