4.7 NWQ-1 DIFFUSERS WITH CIRCULAR CONNECTION
NWQ-1 series swirl air vents are especially useful in comfort airconditioning installations, e.g. in offices and commercial buildings, here they are provided as air-supply and air-exhaust vents. The swirl horizontal air supply ensures the high induction level, fast temperature equalization and fast stream speed drop. The air vents may supply air with temperature differences between +10 and -10 ºK and room height exceeding 2.8 m. The NWQ-1 series swirl air vents include a square front plate, and radial immovable elements directing the airflow. In order to obtain a low level of acoustic power at high efficiency, the triangular parts directing the air reach up to the corners of the square air vent.
