Suspension systems
Suspension.
KE Fibertec’s TBV systems can be supplied with different suspension systems which can be fitted to any type of ceiling. What all the suspension systems have in common is that they are supplied cut to the same length as the textile duct. They are also packaged with the necessary fixing components and a label specifying where they are meant to be installed. See installation instructions and other information at ke-fibertec.com.

Suspension systems.
KE Fibertec’s TBV systems can be supplied with different suspension systems which can be fitted to any type of ceiling. What all the suspension systems have in common is that they are supplied cut to the same length as the textile duct. They are also packaged with the necessary fixing components and a specific label indicating where they are meant to be installed. See also the installation instructions and other information at ke-fibertec.com.
Our textile materials weigh 260-330 g/m2 which is much lighter than metal spiral ducts. Additionally, textile ducts are much easier to handle and transport as they are folded and packed in cartons of a maximum weight of 25 kg.
Curved textile ducts.
Product development of the TBV design now enables us to offer curved textile ducts designed for a specific radius (min. 12 metres) and with Safetrack rails that conform to the shape of the duct. This product can naturally be combined with both ordinary passive low impulse systems and with our hybrid solution in which the low impulse system is made with lasercut inject holes. A good example is above system that KE Fibertec delivered to Broomfield Hospital in Chelmsford, England.
Safetrack Arches.
Dual Arch
Dual Arch mounting brackets utilise the stability of double rails and at the same time they are quick and easy to install. Large textile ducts will be stably suspended both with and without air and installation time is reduced considerably as the ducts are mounted in a single ceiling rail.
Duct Arch
Duct Arch is a pre-bent aluminium rail mounted in hidden sewn-in pockets in the TBV ducts. The Arches reduce sagging when the air is off and prevent popping with ON-OFF start. The unique Safetrack is designed in a way so that the Arch brackets are easily clicked onto the ceiling rail without any tools.
Safe 360
The Safe 360 system consists of removable rings per 1000 mm or 500 mm. The stainless steel rings are locked with velcro (12, 3, 6 and 9 o’clock) inside the ducts so that they can easily be removed for washing. The ducts will keep looking inflated, and it is our best solution if popping is a big problem.
SafeStretch tensioning system.
With the SafeStretch® solution the textile duct system will always look nice and taut with or without air pressure.
• Internal structure while still keeping a generally unobstructed airflow
• Eliminates inflation pop
• Eliminates sagging
• Eliminates wrinkles
• Easy installation and maintenance
The SafeStretch® System is easy to install and basically consists of two tensioning devices - a fasterning section at the duct inlet and a tightening device at the bottom that creates the necessary inflation of the duct.
A Safebracket is fed vertically into the textile duct and into the cross brace which is fitted to the included SafeStretch® bottom ring. Then the Safebracket is clicked onto the Safetrack rail and the duct can be stretched (typically 3-5 cm) until the duct is taut and without wrinkles. The desired position of the Safebracket is held in place by fastening the screw against the Safetrack rail.
The system is easily taken down for washing etc. without the use of special tools.
Typical layouts.
KE Fibertec’s philosophy is to begin with our customer’s actual requirement and from there devise a technical solution with the purpose of creating the perfect indoor climate. This is why we call it: Design The Way You Want. The important aspect of all our solutions is that the relevant room conditions are compared with an ideal solution model so that the layout selected for the system will ensure that the air is distributed as it is supposed to be, without any problems with draughts, pulsations or noise.
Round ducts.
A textile based ventilation system comprising round ducts can be assembled from many types of bends, elbows, fittings and offsets. What all the components have in common is that they are joined together using a zipper, providing a smart, practical solution.
The figures and pictures show different components which can be assembled to produce the final layout. Any angle can be selected for elbows and bends, and conical transitions and T-pieces can be produced in different designs.
Available layouts:
• Round ducts
• D-shaped ducts • ½D-shaped ducts
Offset with 45° elbows
Attachment with offset on top using a 45° elbow
90° bends

Half round (D) and quarter round (½D) ducts.
D-shaped and ½D-shaped KE-Interior Systems have been specially developed for comfort ventilation, which is why there are often major requirements in terms of their finish.
As a result, KE Fibertec puts great emphasis on the fact that these systems are highly flexible and can be produced using countless layouts. A KE-Interior System based on these ducts can, just like round ducts, be created using many types of bends, fittings and offsets, which are joined together using a zipper, providing a smart, practical solution.
KE Fibertec offers a variety of air inlet options for KE-Interior Systems, specifically round inlet sockets, an inlet socket through the top, a D-shaped inlet socket and a rectangular inlet socket can be used as part of the installation. In the case of false ceilings, it is recommended that the air inlet pass through the roof so that all the spiro ducting can be hidden. The top of the ducts (the roof) is made of a textile material which will allow a little part of the air through. This will also prevent any formation of mould between the duct and ceiling.
D-shaped ducts can also be produced as curved ducts which are easy to include as an elegant architectural element in office buildings, canteens etc.

Indoor Climate and Acoustics.
A good indoor environment with proper acoustics is key for the well-being and concentration of the employees. A well-dimensioned ventilation system must therefore be silent. Textile ducts have a positive impact on room attenuation as they act as sound baffles in the ceiling.
