Diffused Airflow Direction 360° 360° 360°
Characteristics of Diffused Airflow Since the outlet is larger than the neck diameter, even if the wind velocity is high, the wind velocity is lowered on the outlet side and a low-pressure surface is generated inside the diffuser, and as a result the diffused air is mixed with the indoor air.
Therefore, compared to other outlets, even though the wind velocity is increased or the temperature difference is increased, ventilation is not felt.
Air Volume Control Use the handle attached to the center of the front of the diffuser
Structure Wings can be separated from the front of the diffuser

*1. The diffusion radius (m) is the value when the wind velocity (m/s) of the airflow is 0.5 or 0.25.
*2. Noise level = Outlet noise level-indoor diffusion attenuation (8db) (less than 20 is not indicated)
