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,
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 CO2
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.

0,5 à 1 m
Kanaal naar dakdoorvoer: verloop van 125mm
naar 160mm. Gebruik geen flexible verbinding.
Vermijd bochten in dit kanaal.
Indien de DucoBox niet in het beschermd volume zit
dient deze leiding thermisch geïsoleerd te zijn.
Plaats een
akoestische
demper van
minimaal
0,5à1m per
aansluitmond
die naar
een andere
ruimte leidt.
> 90°
160
mm
125 mm → ≥ 30 m³/h
100 mm → < 30 m³/h
< 90°
Beperk de overdracht van trillingen.
• Gebruik Silent Block bij
bevestiging van de DucoBox.
• Gebruik beugels met rubber inleg.
Kanaaldiameter:
125 mm vanaf 30 m³/h
100 mm kleiner dan 30 m³/h
of equivalent mits berekening (bv. bij instortleidingen)
Zorg ervoor dat de totale tegendruk zo laag mogelijk is
(streefdoel ≤ 150 Pa) en de luchtsnelheid in elk kanaal
kleiner is dan 3 m/s.
Vermijd zo veel
mogelijk bochten
en maak ze nooit
scherper dan 90°.
Vermijd deuken en vuil in de kanalen.
Plaats geen
afvoerventiel
rechtstreeks op de
DucoBox. Gebruik
een bocht tussen de
box en het ventiel.
Gebruik ventielen
met een zo laag
mogelijke tegendruk
en volg de instructies
zoals aangegeven in
de handleiding wat
betreft de opening van
het ventiel.
Maak de gekoppelde
kanalen luchtdicht
vast via tape,
slangklem of
tiewrap. Gebruik
geen schroeven bij
bevestiging.
Kies een dakdoorvoer met
lage weerstand.
Houd de DucoBox
luchtdicht. Sluit het deksel
goed en plaats een dop
op elke niet-gebruikte
aansluitmond.

De goede werking van uw Duco ventilatiesysteem is volledig afhankelijk
van de keuze en uitvoeringskwaliteit van de afvoerleidingen!
10 NIET TE MISSEN TIPS
DISCLAIMER: aan dit document kunnen geen rechten
ontleend worden. Alle tips zijn louter adviserend.
Elke uitvoerder kan afhankelijk van het project
naar eigen goeddunken bepalen welke
tips haalbaar en/of nuttig zijn.
Werd het kanalensysteem geoptimaliseerd?
Vraag professioneel advies bij uw
leverancier van kanalen. Het bespaart u tijd,
verzekert u kwaliteit en levert energetisch
voordeel op voor de eindgebruiker!

03.C Air duct
connections
Keep down restriction. A non-return flap is
required when discharging into a manifold.
Be sure to take note of the ‘10 unmissable
tips’ as well when fitting the DucoBox. Avoi-
ding excessive use of bends, especially angles
greater than 90° and adhering to the diame-
ter guidelines for the ductwork will ensure
that the ventilation box is able to do its job
satisfactorily. Failure to take account of this
recommendation may result in a highly energy
and maintenance-intensive system that gives
rise to frequent excessive noise levels.

The DucoBox Silent communicates with slave components through a wireless (RF)
connection. RF components have a maximum free-field range of 350 metres. This
distance will be much less in a building because of obstacles. Therefor you will
need to allow for features such as walls, concrete and metal. All slave components
(except those which are battery powered) also act as repeaters. Signals from com-
ponents that are unable to make a (strong) connection with the master component
are forwarded automatically via no more than one other component (= hop point).
Please refer to information sheet RFcommunication (L8000018) at www.duco.eu
for further information.

Illustrations and connections may vary depending on product configuration. Incorrect connection or failure
to follow the instructions may result in damage to the connected devices.
RF obstacle-free zone
Do not place any obstacles causing RF interference or other devices with an RF
connection within a radius of at least 30 cm around the RF component. We take these
to include items such as washing machines, tumble dryers, ironing boards, etc.
