Rectangular double deflection grille

GTH is a rectangular grille for supply air. It is designed for wall mounting. The grille has both horizontal and vertical air deflectors which can be easily adjusted on site so that the throw and spread pattern are correct for: over- or under-temperature conditioning, location of the diffuser, furniture in the room and obstructions to the air flow. In order to regulate or measure the throw, GTH must be used together with the commissioning box TRG.
