FabricAir Trevira

FabricAir® Trevira is a permeable fabric woven with permanently flame-retardant fibers and yarns. It is especially suitable in places where there is a risk of bacteria growth or condensation, such as the food industry or indoor pools.

FabricAir® Trevira is supplied with a 5- or 10-year warranty and all variants are Oeko-Tex 100 certified.

All suspension types are available, including All-in-One, which always keeps the duct stretched out even when the air is removed from the system.

FabricAir® Trevira is machine washable and retains its dimensions after washing (max. 0.5% shrinkage). The permeability is uniform (max. 5% variation).

The fabric is supplied in standard colors, with the option of custom dye, surface prints and other custom prints.


FabricAir Trevira CS100 comes with a 10-year warranty.


FabricAir round duct is the most commonly used duct profile and is typically found in open ceiling applications. The duct diameter can be made as small or as big as required.

The Circle Section duct can be used when there is a hard ceiling to attach to. Typically this profile is used when there is not enough head room to allow for the use of a Half-round duct.

Flow models



In FabFlow™ the air exits the duct through the permeable fabric surface. The air is driven by thermodynamic forces preventing drafts in the occupied zone, which results in a high level of comfort.



With MicroFlow™, the air exits the duct via laser-cut micro-perforations on a larger percentage of the duct’s surface area.
When used as the primary flow model, the perforated area covers between 25% to 100% of the duct’s surface area.
MicroFlow™ has the smallest near-zone of all of the perforated fabrics available; the near-zone will not extend beyond 300 mm [≈12 in]. 



WithPerfoFlow™ the air exits the duct via laser cut perforations along the circumference of the duct.

The perforations can cover between 90° and 360° of the duct’s circumference.

The size of the near zone depends on the static pressure inside the duct, the percentage of the circumference that is perforated, and the size and spacing of the perforations.  



SonicFlowTM is a directional flow model where the air exits the duct via rows of laser cut perforations. Multiple rows of SonicFlowTM can be specified for a duct, with each row covering a maximum of 30° of the circumference. The throw depends on the static pressure inside the duct, the size, and spacing of the perforations.



OriFlowTM is a directional flow model where the air exits the duct via rows of laser cut orifices. Multiple rows of OriFlowTM can be specified for a duct. The throw depends on the static pressure inside the duct, the size, and spacing of the orifices.



NozzFlowTM is used in applications where very precise directional airflow is needed. The discharge coefficient is almost at unity due to the shape of the nozzle. This results in higher discharge velocities than an equivalently sized orifice, and longer more directional throws.




JetFlowTM is capable of generating exceptionally long throws through the use of conical jets in varying diameters.

The jets have a very high discharge coefficient due to the conical shape.

This results in higher discharge velocities than an equivalently sized orifice.

Colors and special dying

FabricAir ducts are available in a variety of standard colors and custom colors upon request.


The ability to launder FabricAir ducts is one of the many unique advantages of selecting fabric over metal ducting.

Shrinkage is less than 0.5%

Duct shrinkage can be a serious problem if uncorrected. Suppose you take down a duct to wash it and afterwards it is two feet shorter and two inches smaller in diameter.
