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.
Operation data concerning to diffuser without damper or with open sliding damper.
Operation data concerning to diffuser with deflectors in working position with 50% reduction of the effective air passage surface.
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.
Vk: effective speed (m/s)
m³/h: air flow
Pa: pressure drop in Pascal
L(m): air throw in meters
dB(A): noise level
