If a distance of 2 m cannot be maintained, the pipes will have to be arranged
in an offset manner. This make makes it possible to achieve a drop of pres-
sure between the intake airs and exhaust air, since the pipes are located in
different flow rate areas.
The distances of the aspiration apertures to each other and to the wall of the
duct are represented in the following table.
Duct cross section
≤ 0,5 m²
Duct cross section
> 0,5 m²
Distance from aspiration
apertures to wall
100 to 200 mm
200 to 300 mm
Distance of aspiration aper-
tures to one another
100 mm
150 mm
The diameter of the sampling aperture results from the number of aspiration
apertures. The precise value can be found in Chapter "Simplified pipeline
project planning”..
The pipe is concluded with an end cap without a bore.
The aspiration apertures should be arranged against the air flow.
During project planning, it is to be taken into account that the air conditioning
ducts for mounting the pipe system are often only accessible from two sides.
The following illustration depicts two project planning examples of pipe sys-
tems in air conditioning ducts.
