Ceiling Swirl Diffuser DQJA / DQJR Description The swirl diffuser type DQJA / DQJR was developed especially for installation in grid ceilings. Its main field of application is for comfort rooms up to a maximum air change rate of 12. Unlike the conventional ceiling diffusers, the built-in air deflection blades can also be adjusted at a later stage. By lifting the horizontal throw blades, the jets are lowered toward the vertical direction. The blades can be adjusted to achieve a vertical outflow. The horizontal throw is preset in factory. A volumetric flow meter can be integrated into the spigot...
