Air supply options: With Duco’s Demand-Controlled Natural Ventilation Systems a wide range of self-regulating (SR) ventilation louvres is available for the supply of fresh air� From standard
self-regulating louvres which can be fitted in every kind of window or installation site, to louvres with sound absorbing qualities for projects where there is exposure to (mild) levels of noise, fire-
resistant louvres, custom louvres for high-rise buildings, to ventilation and solar shading in a single product or electronically controlled louvres with preheating� See www�duco�eu for more info�

Congratulations on your DucoBox Focus, the
smartest box in Europe! The DucoBox Focus
performs two functions in a Duco De-
mand-Controlled Natural Ventilation System:
On the one hand it is the extractor fan that
exhausts contaminated air with excessive CO
2
content or relative humidity� Thanks to integra-
ted control valves, air is only exhausted in the
zone that requires it�
On the other hand it is the system master or
brain of the system� It receives and interprets
signals from slave components (measurements
from sensors or manual input), on the basis of
which it controls the ventilation system�
It is inadvisable to connect the DucoBox (via a
duct or directly) to an extractor hood, regar-
dless of type� This usually causes excessive fou-
ling in the DucoBox, which affects its operation
or has a more direct effect on output�
