Operating data

Data referring to 1m long diffusers, with a terminal throw velocity Vt = 0.25 m/s and with a temperature differential of 10/12°C in ceiling insallation and side air throw.
The position of the deflectors reduce the effective section. When the deflectors are open or in return mode, the air flow (m3/h) could be increased.
