Application and Characteristics
It is available in three structural forms: 90°, 180° and 360°, which can be installed in corners, walls and open spaces respectively. It consists of a top air duct connector and an air supply panel with a certain opening ratio.
It features a large airflow diffusion radius, low flow velocity and soft air supply. In addition, the displacement diffuser is equipped with an internal filter screen to achieve environmental protection and noise reduction effects.
