Square diffusers are commonly used air outlets in air conditioning systems, featuring uniform air dispersion and a sleek, aesthetically pleasing design. They can be made in square or rectangular shapes to match any ceiling finish requirements. The inner core of the diffuser can be detached from the outer frame for easy installation and cleaning. A damper can be added to control and adjust the air volume. Suitable for studios, theaters, classrooms, concert halls, libraries, gaming rooms, theater lobbies, standard offices, shops, hotels, restaurants, and sports arenas. To avoid noise interference and discomfort in various environments, in addition to determining the neck wind speed according to the performance chart, the installation height and location should also be considered.
