that the ventilation box is able to do its job
satisfactorily� Failure to take account of this
recommendation may result in a highly energy

10 UNMISSABLE TIPS
The smooth running of your Duco ventilation system is totally dependent
on the choice and the quality of implementation of the duct system!
Has the duct system been optimized? Ask
professional advice from your duct supplier. It
saves you time, ensures quality and provides
energetic advantage for the end user!

directly on the box.
Use a 90° bend
between the DucoBox
and the valve. Use
valves with an as low
as possible back-
pressure and follow
the instructions as
given in the manual
regarding the opening
of the valves.
4
Avoid as much as
possible the use of
curves. Avoid sharp
< 90°
angles.
5
Assure an airtight
connection by using
tape, clamping strips
or tie-wrap. Do not
use screws.
6
Avoid bumps and dirt in the ducts.

Duct leading to the roof pass-through: use a
reducer 125 mm – 160mm. Never use flexible
connections. Avoid curves in this part of the
canalization. If the DucoBox is not mounted in a
protected (insulated) volume, this duct needs to be
thermally insulated.

Reduce the transmission of
vibrations:

• Use Silent Block elements when
mm
fixing the DucoBox to the wall.
• Use duct suspension clamps with
rubber.

Diameter of the ducts:
125 mm upward from 30 m³/h
100 mm less than 30 m³/h
Or an equivalent based on a specific duct calculation
(p.e. for ducts placed in floor screed). Make sure that
the total counter pressure in the ducts is as low as
possible (preferably ≤ 150Pa) and that the airspeed in
every duct does not exceed 3 m/s.
125 mm → ≥ 30 m3/h
100 mm → < 30 m3/h
