Air supply options: With Duco's Demand-Controlled Natural Ventilation Systems, there is a choice from a wide range of self-regulating (SR) window ventilators available for the fresh air supply�
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 Silent
Connect, the quietest box in Europe! The
DucoBox Silent Connect performs two
functions in a Duco Demand-Controlled
Natural Ventilation System:
On the one hand it is the extractor fan
that exhausts stale air with excessive CO
2
content or humidity�
On the other it is the system ‘master’ or
brain of the system� It receives and in-
terprets 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, regardless of type� This usually
causes excessive fouling in the DucoBox,
which affects its operation or has a more
direct effect on output�
