Operating data

Vk: effective speed (m/s)
m³/h: air flow
Pa: pressure drop in Pascal
L1 (m): data referring to a terminal throw velocity Vt = 0.25 m/s and with a temperature differential of 10/12°C in ceiling insallation (not higher than 3 m); for longer distances, it needs to correct the throw multiplying it by 0,7.
dB(A): noise level

Dimensions are expressed in mm.
