Air ducts
Choosing air ducts
Flow rate and maximum air velocity are defining factors in
choosing the right ducting in order to avoid generating any
extra obtrusive noise and pressure drop (see table)�
Make sure that the total counter pressure in the ducts is
as low as possible (preferably ≤ 150Pa) and that the air
velocity in every duct does not exceed 3 m/s�
Integrating connecting sleeves
Based on the chosen duct diameter, connect the appropriate connectors (with rubber) to the ventilation unit� The 4 connection noz-
zles on the ventilation unit have a diameter of Ø160(F) for DucoBox Energy D225/D325 and Ø180(F) for all other versions�
Choice of connectors (with rubber):
