Support systems


Textile ducts are compatible with several types of support systems.
The choice of support system depends on several criteria:
  • Diffusers’ shapes and cross-sections
  • Building constraints
  • Supply and fitting costs

Cable suspension

Support systems
This system is only used for circular diffusers.
Cable suspension is the system most frequently used. It is the most economical solution in terms of supply and fitting times per meter.
It can be adapted to the widest possible range of constraints (wall or ceiling fitting, changes in level, etc.).
The position of anchoring points must be included in the study. Tractive forces may be up to 250 kg.

To prevent any cable sag, intermediate supports are recommended every 10 to 15 metres.

Rail suspension

Support systems
The Twist’n Fix rail can be used for circular or semi-circular diffusers.
This support system developed by ATC offers interesting savings in fitting times.
Only one rail is needed for textile ducts up to 1,000 mm in diameter.
Thanks to its novel technical characteristics (ultra-rapid connectors), the Twist’N Fix system reduces the number of handling operations to be carried out at high levels by privileging pre-assembly on the floor.
It is especially recommended for refurbishment projects.
Special efforts have been made to make product-handling easier. Aluminium rails are in the form of strips, 3 metres long.

Profile suspension

Support systems
This system is mainly used for diffusers with semi- and quarter-circular cross-sections.
Using rods that act as links, the profile suspension system gives continuous, accurate guiding and provides the strength required for holding the ducting in shape.
Use of PVC or aluminium profiles means that smooth, flat surfaces are required for fitting.
Rollers or slides may also be used, but the diffuser / profile link is less accurate.
