Abstract
An air diffuser adapted to be mounted in a suspended ceiling and connected to the air supply duct of a ventilating system to diffuse air horizontally along the ceiling at an adjustable flow rate. An upper plate is designed to be supported on the rails of a suspended ceiling so as to be levelled with the ceiling tiles. A lower air deflecting plate is suspended from upper plates, the upper plate has a central hole for communicating with the air duct. Baffle plates are hinged to the underside of the upper plate along hinge axis which are parallel to and inwardly spaced from the free peripheral straight edges of the lower plate. The baffle plates can be manually adjusted and are maintained in an adjusted angular position between a fully-opened position in which they rest against the underside of the upper plate and a closed position with their free edges resting on the lower plate. Each baffle plate is independently angularly adjustable, such that the air can be discharged at adjustable volumes and selectively in various directions around the diffuser.
