Everything is included in a FabricAir dispersion system

Many functions known from conventional metal ducts are fully integrated in a FabricAir dispersion system, 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.

30-70% less expensive than metal

FabricAir dispersion systems offer multiple opportunities to save money without sacrificing quality or flexibility in design. Utilizing FabricAir dispersion systems can result in 30-70% savings over the cost of conventional ducting through a simpleinstallation process, economical shipping solutions, space-savings and efficient materials.


The hygienic alternative to metal

FabricAir ducts are 100% polyester, making them a hygienic choice for your air distribution. Polyester is a thin plastic thread that does not absorb water. This makes it impossible for bacteria to live "inside" of the fiber and should any dirt accumulate on the surface of the duct, it can simply be washed. If you have an application that is likely to deposit harmful bacteria on the duct, such as food processing, you have the option of specifying one of our anti-microbial polyester ducts. These unique qualities make FabricAir dispersion systems the preferred choice in slaughterhouses, laboratories, professional kitchens and any other location with strict hygienic requirements.

A versatile system design

FabricAir dispersion systems do not have limitations when it comes to elbows, reducers and take-offs, such as conventional metal ducting does. If you can imagine it, FabricAir can produce it. If you are used to metal ducting then you know to take your wallet out when you hear "non-standard". At FabricAir, non-standard is what we do, because every job is custom. Any angle, any length, any diameter... Give us a call and we will turn what you have imagined into reality in three weeks or less.


The entire duct is an air diffuser

In a FabricAir dispersion system the fabric ducts distribute air along the entire length of the duct at the desired angle. The full length even air distribution is a standard feature of FabricAir dispersion systems and does not come with a significant price premium, which is the case when using conventional metal ducts. The full length distribution comes in two varieties: Linear Flow Models (LFM) and Surface Flow Models (SFM). These two methods can be co-specified as needed. For example, a swimming pool would require a permeable fabric to avoid condensation; an SFM. It would also require a type of LFM, like SonicFlow™, to wash the perimeter surfaces.

Full length air dispersion is enabled through permeable fabrics and directional perforations in the surface of the ducts. This creates uniform, draft-free and condensation-free air distribution throughout the entire space, regardless of system complexity.

Metal ducts need grills and diffusers, which results in highly complicated installations and higher energy consumption. These additional fittings often cause uneven air distribution and add to the expense, space requirements, man hours, etc. of the project. Such uneven air distribution is a major cause for uncomfortable and unhygienic work environments as they lead to draft and condensation problems. 

At FabricAir we design our air distribution and air dispersion systems with efficiency and excellence in mind. The fabric ducts are breathable, which makes every part of the duct functional and efficient, creating a uniform air distribution. Higher control and precision provides the area with a superior comfortable climate as far as ventilation, heating and cooling is concerned.

Full-length air dispersion allows for the gentle, noiseless exit of air from the duct surface. Ideal comfort with lower energy consumption is achieved through combining flow models to suit the specific area requirements. The use of tailored flow models allows the system to suit virtually any design requirement the end-user has without compromising the air dispersion results.

Easy installation

FabricAir dispersion systems are intuitive and simple to install. Each duct section is marked with an individual tag, which lets you know exactly where each piece should go. There are no trade specific tools required; everything you need can be found in a handy-man's tool box. Easy installation significantly reduces labor hours compared to metal ducts or other fabric duct systems. This helps to ensure that your project is built on time and within budget.


The most reliable lead times in the industry

FabricAir has the fastest standard delivery times of any fabric duct manufacturer and consistently delivers on schedule. If you have ever had a project delayed because your equipment didn't arrive on time, then you know the importance of on-time delivery and how your bottom line can be affected. Often there are liquidated damages incorporated into construction contracts, and your customer isn't interested in why you weren't able to complete a project on time. Don't let a manufacturer be the reason. FabricAir will always deliver on time.

We are experienced professionals and we use state of the art production technologies to ensure that we have the best and most reliable lead times in the industry.

Sustainable ventilation with a low carbon footprint

FabricAir dispersion and distribution systems have a smaller carbon footprint than conventional metal ducting. FabricAir ducts require less energy to produce and transport, and with a significantly lower weight fabric ducts place considerably less load stress on the construction, making the system ideal for retrofitting as well as new builds.

The efficiency of air distribution in fabric ducts is much higher and more precise than with conventional metal ducting. This means they can run at a low static pressure drop and require less energy to operate.

The ductwork will last for a long time. Many of the original 1973 installations are still in use today.

FabricAir meets the OEKO-TEX 100 requirements, proving that we are committed to environmentally friendly production methods and materials. 


Long lasting

FabricAir is the original fabric duct manufacturer. We introduced the world's first fabric duct in 1973, thus have more than 40 years of experience. Many of our initial installations are still fully functional and perform just as well as the day they were installed.

Efficient solution regardless of ceiling height


Depending on the application, FabricAir ducts and dispersion systems can be tailored to suit the specific needs of your building, by using the best flow model or combination of multiple flow models.

For example, in buildings with low ceiling heights, low-throw air flow models are often the option of choice to eliminate drafts. However, if the building has high ceilings and requires heating, high-throw flow models are used to ensure that the air reaches the occupied zone and to help avoid stratification. FabricAir dispersion systems ensure the ideal air distribution regardless of room size and ceiling height.


Lightweight design for heavy duty ducts

FabricAir offers the most heavy duty ducts in the industry, in a lightweight design. Our ducts weigh as little as 300 g/m² [8.8 oz/yd²], thus it is like comparing a feather to a hammer, when compared to conventional metal systems. This is important especially in connection with retrofitting existing building mass, as FabricAir dispersion systems will not significantly affect the structural integrity. As a quick rule of thumb, using 3 kg/m [2 lbs/ft] for calculation purposes will provide a fair conservative estimate for the structural engineer in 99% of all project. The weight of an actual duct with suspension depends on the length and diameter of the duct. However, most popular fabric, Combi, weighs approximately 1/20 of steel sheet ducting.

A flow model to fit your specific needs

FabricAir produces many different flow models to meet the specific demands of any project. The appropriate flow model depends on a number of project specific factors. What type of conditioning is being supplied: heating, cooling, ventilation, or a combination of the three? Are there any specific air velocity requirements? Do the requirements differ from room to room? There are more questions that may be asked, and the answers determine what flow model will be the best fit for your application. Rest assured, no matter what the requirements are for your application, FabricAir has the flow model to fit your needs.
