NRA is a ceiling diffuser, for both summer and winter application, equipped with a vertically adjustable front plate design, in order to obtain either a concentrated long airstream or a short diffused throw length. The horizontal air deflectors that can be found inside the supply air diffuser, can be adjusted either manually (NRA) or with a Belimo LM-24 (NRA-M) actuator. NRA ceiling diffuser is best suited for ventilating, cooling and heating larger public facilities, such as sport halls, department stores, warehouses, industrial buildings etc., where a long distance throw length and high ventilation efficiency is required, and for highest efficiency it is recommended to use it together with Airvent's TIDEC system which also makes automatic control possible. The unit can be installed in false ceilings or free hanging.
