Operating data

Vk: effective speed (m/s)
m³/h: flow rate
Pa: pressure drops in Pascal
L1 (m): air throw of air jet without damper, with a blade deflection of 0°, with coanda (ceiling) effect, terminal velocity 0.25 m/s and Tmax 15°C
dB(A): noise level

All dimensions are expressed in mm.

When ordering, indicate the diameter of the duct where the air jet will be installed.
