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 window ventilators which can be fitted in any kind of window or installation situation, including window ventilators with sound absorption for projects where
there is exposure to (mild) noise levels, fire-resistant window ventilators, customised window ventilators for high-rise buildings, as well as ventilation and solar shading in a single product or
electronically-controlled window ventilators with preheating� See www�duco�eu for more information�

Congratulations on your DucoBox Silent,
the quietest box in Europe! The
DucoBox Silent 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 which receives and interprets
signals from slave components (meas-
urements 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�
