9 Guide conducts VIS 2xx / VIS 3xx
This chapter contains some recommen dations based on our experience about the se-
lection of guide conducts for the inspection in tubes and ducts.
As all tubes and chimney systems are different, the user has to decide about the guide
conducts in every single case. For the selection of the correct tool it is important to
consider that the guide conduct has to facilitate the introduction and the extraction of
the camera head, as well as an adequate guidance. The danger of jamming or getting
stuck in the tube has to be avoided.
NOTE!
The information given in this chapter only refers to the accessories. Chapter 3.1 explains which camera system can be used in which tube.
Ø 40 - 50 mm
Use the service camera without accessories.
Ø 50 – 70 mm You can use the service camera without accessories. The
lens can be protected by the guidance sleeve. If there is
water and mud in the horizontal part, we recommend to use
the roller guide.
Ø 70 – 100 mm The inspection is possible with the roller guide and without
it. Use the guidance weight for the vertical inspection or for
the inspection of downpipes.
Ø 100 – 154 mm
A centering brush can be used with the roller guide or with-
out it and with the lens protection.
