Everything is included in a FabricAir dispersion system

Many functions known from conventional metal ducts are fully integrated in a Smart Air Solution from FabricAir, making diffusers, grilles, dampers, etc., redundant. FabricAir dispersion systems are all inclusive.

You can forget about the following when using fabric air dispersion systems:

  • No extra grilles or diffusers are necessary. The FabricAir dispersion systems function as both a duct system and as an air dispersion system.
  • No extra noise reduction is needed (except perhaps reduction of fan noise). Noiseless is the standard.
  • No inconvenient alterations or assembly on site. A FabricAir dispersion system fits straight from the factory, is assembled with zip fasteners and is ready for installation as soon as it arrives.
  • No damper is necessary. A FabricAir dispersion system does not require balancing.
  • Painting is not necessary as the fabrics are dyed.
  • No extra insulation is necessary. FabricAir dispersion systems are condensation free.

This is what makes fabric-based air dispersion a Smart Air Solution.

Fabric ductwork is 30-70% less expensive than metal
The Six Key Elements of Savings with FabricAir Dispersion Systems

Switching from conventional metal ducting to Fabric ductwork technology enables saving of up to 70% on total installed costs. The total savings potential on a project varies from 30% to 70% over the cost of conventional solutions without sacrificing quality or flexibility in design.

Utilizing our fabric ductwork based Smart Air Solutions results in significan savings through six key elements: simple installation process, economical shipping solutions, space-savings, greater design flexibility, efficient materials and a long service-life


There are many considerations when evaluating noise levels in any given space. Air distribution is just one of those factors. With FabricAir ducts you can concentrate on the other factors because fabric is not rigid, like metal ducts, and therefore does not transmit noise. FabricAir systems typically operate in the 25-30 NC level range, but can be designed to go as low as NC 15.

Virtually silent air dispersion

Traditional ventilation systems generate noise as the air passes through the ducting and into plenum boxes and out through spot diffusers. Fabric-based air dispersion solutions create minimal resistance, thus no significant sound – as low as NC 15.

Noise level considerations differ vastly from application to application. Libraries, theaters, auditoriums, concert halls, recording studios and religious facilities are examples of applications that require very low levels of noise; hence, minimizing noise transmissions and controlling sound characteristic within the space are crucial.

The acoustic environment is influenced by many factors incl. the geometry and volume of the space; transmission, reflection and sound absorption capabilities of the materials used and surfaces inside and surrounding the space; and airborne and structure-borne sound transmission. Unwanted sounds and noise pollution can have a negative impact on health and wellbeing of the occupants, as well as on their communication and productivity. This is why minimizing the noise contribution from the ventilation solution is important.

FabricAir systems typically operate in the 25-30 NC level range, but can be designed to go as low as NC 15. This makes the technology ideal in comfort applications, as the ventilation system then does not contribute negative noise pollution to the space being conditioned. This is why fabric-based air dispersion solutions are the popular choice for theaters, concert halls, schools, and so forth.  

Fabric air dispersion as an acoustic element

Conventional ventilation solutions in metal are rigid and therefore transmit noise. Structural vibrations manifests themselves in the metal, sounds reverberate off the surface, and the airstream generates noise as it travels through the system. The classic ducts may also transport sounds like speech directly from spot diffusers in one room to spot diffusers in adjacent rooms, e.g. in an office structure.  

Fabric ducting differs from metal solutions in that they have acoustic absorption properties and do not transmit sound. This is important, as it reduces sound reverberation, by hindering the sound reflecting back into the space from the duct surface. The fabric fibers are a so-called porous absorbent that absorbs the sounds by turning sound waves into heat energy. This happens as the fibers are forced to bend by the sound waves.

In comfort applications the acoustic properties of fabric ducting are highly relevant. Sound absorption reduces reverberation time, which increases conversation privacy, makes speech more intelligible and can help reduce the general noise level in the space. This leads to a greater level of occupant comfort. The virtually silent nature of the technology means that the fabric duct system doesn’t transmit noise.

In applications like theaters, auditoriums and concert halls, conventional solutions often fall short, as they require large orifices to generate a high air change. This results in unpleasant, even unhealthy drafts, as well as transmission and reverberation of noise. The same is true for silent applications such as libraries and religious facilities. Fabric-based air dispersion technology is draft-free and virtually silent, thus offers the ideal environment in these application types. They provide a high air change with great levels of comfort.

FabricAir dispersion systems are fully customizable and can be tailored to your specific needs. We have a dedicated engineering department to help design the optimal duct system using our proprietary 3D software.

Balancing is not necessary
Balancing is not necessary

FabricAir dispersion systems do not require field balancing. Due to the intelligent system design and the nature of our materials, we do not apply diffusers, grills or dampers and thus do not have to balance the system once installed.  We do all the "balancing" at our factory so you don't have to. With conventional metal ducting, a series of tests are necessary to ensure that the system runs as required. The goal of this airside test and balance is to verify that your terminal device (diffuser) has the specified amount of air flowing to it. This can mean balancing many diffusers and each time one is adjusted the rest of the diffusers in the system are affected, including those that have already been balanced. As a result of this, balancing a metal system is an iterative, time consuming, and inaccurate process where "within 10% of specifications" is considered a success. With a FabricAir dispersion system there is only one place to verify the airflow, namelyat the inlet to the FabricAir system. This way we can be sure that the system is performing as designed.

Colors and Special Dyes

FabricAir ducts are available in a variety of standard color fabrics. Custom dyes are optional with FabricAir® Trevira fabrics. Surface printing technology is available for color printing on FabricAir® Trevira and FabricAir® Combi upon request.

Nozzles, sliders and hooks come in red, blue, white, black, orange or gray. The standard color combinations can be altered upon request within the available color schemes.


Custom Prints

Surface printing is a technique used to create custom colored ducts. Contrary to custom dyes, the surface print only applies custom color to the surface of the duct. The inside remains the original color, which can be seen through perforations, orifices and nozzles. 

Graphical elements, like logos or phrases, and seamless patterns or uniform colors on the ducts are created using different printing techniques. The relevant printing technique depends on the specifics of the project.

Print placement is determined by the duct location in the room and the typical positioning of the onlooker. For example, in sports facilities, the print is angled downward to make it look natural to the spectators. 

Seamless patterns require specially adapted designs or motifs to ensure seamless repeatability and applicability, as they cover the entire circumference of the duct. Using this technique, entire systems in patterned fabrics are created, such as coffee beans for cafés.


Traditional HVAC designs require knowing the dew point of the space being conditioned to avoid condensation on the surfaces of the metal ducts and grills. This phenomenon is referred to as "sweating" in the industry. The traditional fix for sweating ducts is to insulate the entire duct or to use double wall ducting; both of which add significantly to the projectcost. With FabricAir ducts the fix is simple: using permeable fabric. Permeable fabric allows the duct to "breathe", which creates an air blanket around the duct and keeps the duct dry, without trippling the cost!
