GTH is a rectangular supply air grille designed for installation in sidewalls. It has horizontal and vertical air deflectors, which can be easily adjusted so that the throw and spread patterns are balanced for occupant comfort to account for obstructions in the room. If installed with a TRG commissioning box, it may be used to regulate or measure the airflow.
