1,5 km of fabric ducts for the new medical storage facility

Fabric-based air distribution solutions are being increasingly recognized in different industries. Because of its nature, fabric ducts and whole air distribution systems are essential for one particular application – the medical industry. A well-known pharmaceutical group in China built a brand-new medical storage facility and needed a state-of-the-art air distribution solution that would guarantee the highest quality and cleanliness requirements and meet the needed standards. They chose FabricAir to design the best possible solution for the perfect indoor environment of the storage facility.

FabricAir to appear in an international HVAC convention in Madrid

The past few months marked the rebirth of international conventions and trade shows and HVAC industry was no exception. FabricAir, a global fabric-based air distribution solution manufacturer, used this opportunity to appear in many of them all around the world and the last appearance of 2021 will take place in Madrid, Spain. On 16-19 November, FabricAir will appear in C&R Climatization Y Refrigeration 2021 Convention that will be held in IFEMA Feria Convention Center.

The price of a fabric air duct

The price difference between conventional ventilation ductwork and FabricAir dispersion solutions is significant. Socks are a cost-efficient solution due to the nature of the textile-based dispersion technology.

We are often asked “what is the price of a fabric air duct?”. As with all ventilation systems the answer depends on the size of the project. Regardless, the savings potential is significant when compared to conventional HVAC ductwork solutions.

The savings potential varies from 30% up to 70% when replacing metal ducts with air socks. This makes fabric-based HVAC solutions an unrivalled source of value engineering without compromising the indoor air quality.

The technological advantages of fabric ductwork are many, the most prominent of which is the even and draft-free air distribution. The high levels of comfort and hygiene sets air socks apart from traditional HVAC solutions, as does the price of the ductwork and its installation simplicity.

What is the difference between air socks, sox and fabric ductwork?

The simple answer is “nothing”. A sock is a ventilation duct created in fabric instead of sheet metal or pvc pipe. The technology is widely used across the globe, which means it’s a technology with many names.

In Denmark, where the technology was first commercialized, it would typically be known as fabric ducts, fabric air dispersion, or textile-based ducting. Whereas the same technology is known as air socks or simply socks in North America and textile channels across Europe.

Regardless of which expression is used, fabric ductwork has unique technological characteristics that set the solutions apart from steel ducts, Spiro ducts and other HVAC ducts in sheet metal.

Technical properties of fabric ductwork compared to metal ducts

Condensation is a typical concern in HVAC ducting; however, socks do not have the same natural tendency toward sweating as other HVAC ducts do. Permeable textiles prevent the formation of condensation on the ductwork, which is why fabric ducting does not require insulation.

Eliminating the need for insulation provides significant time savings on a project, which naturally also affects the price. The savings potential also includes materials, and the transportation and storage of these during the building project.

Socks can be used everywhere where exposed ductwork would be applicable. Fabric air dispersion solutions are made from fireproof materials and all FabricAir textiles are UL certified. Fabric ducts can even be made from non-combustible fiberglass.

The efficient use of materials does not only affect the price of the air dispersion systems, but also means lower shipping costs. A textile-based ventilation solution fits into just a few boxes rather than the truck loads of materials required to create a metal duct solution.

The birthplace of fabric air ventilation ducts was a Danish meat processing plant. They needed a hygienic solution for their workspaces; one that would create a draft-free work environment without compromising product safety. Through this joint project, FabricAir became the first company to launch modern air sox. This was in 1973.

Since then, the technology has spread across the globe and more producers have joined the industry. Common for all is the desire to create HVAC ductwork in a better, easier and more flexible way to offer a more versatile alternative to steel ducting.

The hygienic nature of fabric ducts stems from the elimination of condensation, which in turn prevents bacteria, microbial growth and mold. Sox, like regular socks, can be machine washed if they get dirty; some textile ducts can even be autoclaved. That cannot be done with conventional ventilation ducting.

Finally, Fabric ductwork offers unique sound-technical properties, which means air socks are the better alternative in noise sensitive applications. FabricAir offers a LowNoise™ solution ideal in libraries, auditoriums, and the like.

Elements Affecting Price of Fabric Ducting

Air socks do not require accessories such as grilles or diffusers, because the air dispersion happens throughout the length and circumference of the entire ductwork. Just like the socks that go on your feet, sox enable air diffusion through permeable fabrics, lengths of perforations or rows of flow models based on orifices or nozzles. In other words, the fabric ductwork breathes.

Due to the lightweight nature and flexibility of sox, the ductwork is much easier to install than steel ducts, spiral ducts and stock pipe or even pvc pipes, fiberglass duct board panels and aluminum ducts. The ease of installation entails significant savings on the man hours involved in the installation process, which naturally affects the price of the air duct solution. 

The price of a ventilation system in metal is typically five times as high as the price of an air sock solution. Thus, the savings potential in switching from metal to fabric is huge. The price difference is chiefly found in the man hours involved in creating and installing the HVAC solution. However, FabricAirdispersion technology also enables energy savings of up to 40% on the running costs of the system.

A conventional metal duct solution requires balancing and often also on site attenuation, insulation and painting. Fabric ducts are plug’n’play solutions that do not require any of these on site adjustments. Air sock systems are made to measure and ready to use straight from the shipping box.
