What are the basic principles of Airsox?

Euro Air’s exclusively designed textile ducts are called Airsox. They’re designed to distribute cold, heated or ventilated air through any building, regardless of size, and can be customised to meet a wide variety of air flow, air velocity and air exchange rates.

Airsox provide a far more even distribution of air compared to traditional galvanized steel ducts. Steel ducts create both drafts and dead zones (areas where the air remains stagnant) depending on one’s proximity or distance from the nearest air vent. By contrast, Airsox distribute air evenly along the surface area of the duct, allowing cold air to pour down and collect uniformly across the inhabited portions of a room.   

Airsox can be installed at very low costs thanks to the lightweight textile material and extremely simple set-up process. This ease of installation also means that textile ducts are very easy to take down, clean and reinstall, encouraging a far cleaner and more hygienic indoor environment. 

Airsox come in a variety of shapes, colours and sizes, and can be customised to meet the aesthetic demands of any architectural or engineering design project. They can even be printed with corporate logos upon request. 

Not only do Airsox provide a draft-free indoor environment, they also contribute to workplace productivity. Tests have shown that an increased air ventilation rate from 10 m³/h to 36 m³/h will raise employee efficiency by 10-20%.

If, on the other hand, the indoor air temperature is lowered from 25°C to 20°C, workplace productivity will be improved by an additional 10-20%.

What shapes do Airsox come in?

Euro Air produces round, half round and quarter round textile ducts. These shapes can be mixed or matched to fit into any architectural plan. Additionally, special requests are always welcome.

We produce our textile ducts at our very own weaving mill in Vejen, Denmark, and can accommodate customised shape requirements accordingly.

We can meet almost any architectural demands when it comes to dyeing our textiles.

How do you mount Airsox?

Euro Air offers a wide variety of mounting solutions depending on the specific shape and system of textile duct, as well as on the conditions of the surrounding facility:

1. Round duct mounted with clips and wire system
2. Round duct mounted with glider or fasttrack with flexrail system
3. Half round or quarter round mounted with fastrack and wingrail system
4. Special solutions

What are the benefits of choosing Airsox?

Steel ducts create both drafts and dead zones (areas where the air remains  stagnant) depending on one’s proximity or distance from the nearest air vent. Over time this uneven air distribution takes a toll on the well-being and comfort of a building’s occupants. In work environments, suboptimal indoor climate conditions can even have a measurable impact on workplace productivity. Euro Air’s textile ducts address all of these concerns and more.   

Airsox come in a variety of shapes, sizes and systems. Our Permeable, Directional Flow Control, Hybrid and High Impulse Systems (to name just a few) are each designed with specific spatial and structural conditions in mind. The wide variety of systems available and the ability to mix and match between them guarantees a bespoke solution for any indoor climate challenge. 

For more information please check our YouTube channel describing all the different flow models.

More benefits of choosing Airsox by Euro Air include:

  • An optimal indoor climate free of drips, drafts and dead zones
  • Energy savings with lower system operating pressures
  • Less stress on ceiling infrastructure with 70-80% savings on weight
  • Reduction of installation costs/times by as much as 70% compared to steel
  • Modular designs with customisable colours, shapes and sizes
  • Flexible materials enabling unconventional placement and easy servicing
  • A more comfortable, hygienic, and efficient workplace environment 
  • Ducts that are non-corrosive, flame retardant, and moisture permeable
  • Significant noise reduction by eliminating vibrating metal components
  • A more even air distribution compared to traditional steel ducting

Why choose Airsox instead of steel ducting?




Textile Ducting:


Steel Ducting: 

Air Distribution


Uniform delivery, no drafts or dead zones


Draft and dead zones occur based on proximity to vents

Cooling Capacity


Reduced as evenly distributed cool air settles uniformly in the occupied area of the room


A higher cooling capacity is often required as uneven distribution stirs warm and cool air around the entire room

Installation costs


Very low: It’s possible to save up to 70% on installation time thanks to the lightweight material and simple modular set-up


High: Steel ducts can weigh as much as 20 times more than textile ducts, resulting in a heavy workload with more complex  handling requirements

Initial costs


Textile materials are typically cheaper than steel, the prices of raw fabrics and yarn are consistent despite economic instability


Steel is typically more expensive than textiles and prices have been rising in response to economic instability



Euro Air can deliver a huge variety of colours to satisfy architectural and branding demands


Painting steel ducts is a time consuming and very expensive process

Air exchange rate


The entire surface area of the textile duct is used as one big diffuser, resulting in a very high air exchange rate


To achieve a high air exchange rate steel ducting systems need to produce powerful, concentrated drafts

Risk of draft in the occupied zone


Even with high air exchange rates the risk of drafts is very low as air is distributed evenly from the entire surface of the duct


There is a high potential for drafts that increases along with the air exchange rate

Weight of section

Ø-500 x 1.000 mm


App. 550 g


App. 8.700 g



The modular textile system from Euro Air is easy to dismantle and reinstall after washing


Cleaning a steel duct is a complex and costly process, this means that cleaning is often postponed or ignored altogether, resulting in a less hygenic indoor climate

Noise suppressed


The light weight and flexibility of the textile material eliminates any need for noise suppression


Noise suppressing steel ducts is time consuming, complicated and expensive, it is rarely pursued as a result

Noise generation


Without vibrating metal surfaces, textile ducts operate cleanly and quietly, eliminating both audible disturbances and high-frequency buzzing


Steel ducts produce a variety of noise issues that increase along with the air flow and exchange rates, over time these disturbances have a measurable impact on workplace productivity and comfort

Are Euro Air’s Products Environmentally Friendly?

Yes, for Euro Air, environmental sustainability is more than just a buzzword. We provide the world’s only Cradle to Cradle* certified textile ducting, CradleSox. Every stitch and fibre of our textile solution is engineered with environmental impact reduction in mind. We’re committed to conserving resources, reducing our carbon footprint, and recycling our raw materials—all in the name of a better climate, indoors and out.

Additionally, textile ducting has many environmental benefits compared to traditional HVAC systems:

-Lower fuel consumption during shipping/transport thanks to lightweight materials
-Lower power consumption during installation thanks to simple set-up
-More efficient heating/cooling/ventilation reduces AHU and power consumption

* Cradle to Cradle Certification was developed by Dr. Michael Braungart and William McDonough as a means of recognizing safer, more sustainable products made for the circular economy. Cradle to Cradle certification encourages manufacturers to carefully consider each material that goes into a product, as well as every resource used in the production process. Cradle to Cradle certified products aspire to be 100% recyclable.
