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.

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 MicroFlowTM the air exits the duct via laser cut micro-perforations along the circumference of the duct. The micro-perforations can cover between 90° and 360° of the duct’s circumference.


With PerfoFlowTM 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. 


SonicFlowTM is a directional flow model where the air exits the duct via rows of laser cut 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.


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.


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.

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.
