Fig. 2.26: Ceiling duct for intermediate ceilings
Aesthetics If room monitoring requires a concealed pipe system installation, then it
can be mounted in an intermediate ceiling. Ceiling ducts into the
intermediate ceiling are then used. The ceiling ducts are – in accordance
with design guidelines – fitted with aspiration reduction films with defined
aspiration apertures (see Chapter 4 "Design"). The ceiling ducts are then
connected to the pipe system via aspiration hoses (see
1HFig. 2.26).
If the length of these hoses is a maximum 3 m, then the design according
to Chapter 4 applies. If because of building circumstances lengths of
more than 3 m are required, the pipe system must be calculated

The ceiling duct can be used for intermediate ceiling boards up to about
35 mm in strength. The aspiration reduction films are available in two
colours (pure white, RAL 9010 and papyrus white, RAL 9018) and also in
special colours on request.
