Why fabric ducts?

Fabric ducts are very well-suited for efficient, uniform, and draft-free distribution of fresh air without "dead zones".

What is a DireJet System?

From a ventilation technology perspective, the DireJet System can be regarded as an active high impulse system for mixing ventilation.

KE Fibertec is the only distributor of fabric ducts that offers five different nozzle sizes:

  • ½"
  • ¾"
  • 1"
  • 2"
  • 2½"





The flexibility in the choice of nozzle size offers great benefits as the DireJet System can then be used in virtually every type of premises that requires mixing ventilation, even in extremely large ones, such as high-bay warehouses or large sports arenas.

The conical nozzles are fitted in holes made of polyester fabric and are secured using a locking ring. The maximum number of nozzles per row per foot is 4 for the ½, ¾ and 1" nozzles. If this is not sufficient, it is recommended to use two or more rows of nozzles.

Where the 2 and 2½"  nozzles are used, it is recommended to use a maximum of two (2) nozzles per foot per row. As the number of nozzles per foot is increased, the individual jets will have an impact on each other, and they will change character from circular (3-dimensional) jets to 2-dimensional jets.

The velocity rate in the flow will also slow down as the induction of room air is limited the closer the nozzles are placed together.

Safetrack Arches


Safetrack Dual Arch
Dual Arch mounting brackets utilize the stability of double rails and are simultaneously quick and easy to install. Large fabric 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.

Safetrack Duct Arch
Duct Arch is a pre-bent aluminium rail mounted in hidden sewn-in pockets in the fabric 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° Arch
The Safe 360 system consists of removable rings per 40" or 20". 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.

Curved fabric ducts

Product development of the TBV design now enables us to offer curved fabric ducts designed for a specific radius and with Safetrack rails that follow 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 impulse system is made with lasercut inject holes.

A good example of the versatility of KE Fibertec fabric duct systems is shown below.



Mount Easy

For systems with difficult access, like in swimming pool areas where the duct systems are suspended above the pool, KE Fibertec offers a solutions with cord pull called Mount Easy. The Mount Easy system enables a single person to install textile ducts of up to 130' from one end.




Coloured rails

Specific types of suspension systems are now also available in any given color. All visible parts are powder-coated in a high impact-resistant quality.
