What is Textile Ducting? A Beginner's Guide to the Future of HVAC Design

Textile ducting can be difficult to wrap your head around. It may be new to Southeast Asia, but elsewhere in the world textile ducting is already being embraced as the next big step in indoor heating, cooling and ventilation technology.  

Learn all about textile ducts with our latest list of frequently asked questions and answers.   

1. What is textile ducting?

Textile ducts are air distribution ducts made of exclusively designed textile materials. They’re designed to distribute cold, heated or ventilated air through any building, regardless of size, and can be customized to meet a wide variety of airflow, air velocity and air exchange rates. Heated, cooled, or ventilated air flows through the duct and exits evenly through the fabric material’s porous surface. Cool air flows down from the entire surface area of the duct and collects naturally in the occupied zone of an indoor space, creating an optimal indoor climate free from both drafts and dead zones. 

2. What are the benefits of Euro Air’s textile ducting?

Euro Air’s textile ducts eliminate draughts and dead zones by distributing air uniformly through an indoor space. Textile ducts heat, cool and ventilate more efficiently than traditional HVAC solutions, resulting in significant energy savings. They are made of non-corrosive, fire-resistant, and permeable non-organic polyester materials, eliminating the buildup of condensation and preventing the growth of harmful bacteria. Their lightweight textile materials reduce stress on ceilings and structural supports while rapidly speeding up installation times. Textile ducts are also incredibly easy to take down, clean and reinstall, encouraging a more hygienic indoor environment. They can be customized by shape, colour, size and air distribution system, providing a bespoke solution to any architectural, engineering or HVAC design challenge.

3. How do textile ducts compare to galvanized steel ducts?

Subject

 

Textile Ducting

 

Steel Ducting

Air Distribution

 

Uniform delivery, no drafts or dead zones

 

Draught 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

Colours

 

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 draughts

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 draughts that increases along with the air exchange rate

Weight of section

Ø-500 x 1.000 mm

 

App. 550 g


 

App. 8.700 g

Maintenance

 

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

 

Cleaning steel ducts is time-consuming and costly, cleaning is often postponed or ignored altogether, resulting in a less hygienic indoor climate

Noise suppressed

 

The lightweight 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 airflow and exchange rates, over time these disturbances have a measurable impact on workplace productivity and comfort

4. Are textile ducts mould resistant?

Yes, Euro Air’s textile ducts are produced from permeable non-organic polyester materials, preventing the build-up of condensation along the surface of our ducts. Hydrophobic surfaces prevent the growth of mould, bacteria and other harmful substances at relative humidities of less than 85% RH. For exceptionally humid environments (>90 % RH),  Euro Air offers the new Antibac-E washing procedure. Instead of applying a traditional treatment with environmentally hazardous silver ions, the Antibac-E process protects textile ducts from microbial contamination for at least 3 washing cycles. Additional treatments can be made with any Euro Air or KE Fibertec washing partner. 

5. Are textile ducts flame retardant?

Yes, Euro Air’s textile ducts are produced from heat resistant and flame retardant materials. They are highly resilient even in environments with extreme indoor air temperatures. Our Nomex textiles are especially well adapted to high temperatures and can continue to perform optimally from -45°C to 100°C. Read more about Nomex here

6. Are textile ducts non-corrosive?

Yes, Euro Air’s air distribution ducts are made of exclusively designed textiles and are therefore immune to corrosion and rust. All of our textiles are woven in our very own weaving mill in Denmark. Read more about our weaving mill and textiles here

7. Are textile ducts clean rooms approved?

Yes, Euro Air’s DFC-HT textile material is cleanroom approved. It is a polyester material made of High Tenacity Filament fibres woven in our very own weaving mill in Denmark. The DFC-HT material is woven in a plain weave consisting of heavy-duty “High Tenacity Fibres” to create a strong, even and wear-resistant textile surface. The DFC-HT material has been approved for cleanroom applications, ISO class 4 acc. to ISO 14644-1.

8. How do textile ducts improve health & hygiene?

The entire surface area of a textile duct acts as one large diffuser, achieving a high air exchange rate without introducing draughts or dead zones. This ensures an evenly ventilated indoor environment while eliminating the need for centralised air vents, which are easily contaminated by harmful bacteria, germs and mould. By contrast, our textile ducts are produced from permeable materials and are condensation free, preventing the build-up of potentially harmful bacteria altogether.  Additionally, textile ducts are exceptionally easy to take down, clean and reinstall, enabling regular washing cycles and encouraging a more hygienic workplace. Euro Air’s textile ducts also eliminate the distracting ambient noises produced by vibrating metal components in traditional HVAC systems, resulting in a happier, more productive workplace.

9. How do you clean textile ducts?

Washing instructions vary between permeable and non-permeable textile materials.

Textile ducts made of the permeable TCS, Nomex, and DFC-HT materials:

  • Can be washed in a regular washing machine, however, the machine should only be half full.
  • For food industry applications, the ducts must be turned inside out before washing.
  • Wash at 20-40°C using ordinary detergent until the washing water is quite clean. Each wash should last about 15 minutes (if the ducts are heavily soiled they should be rinsed between the washes). After washing the ducts must be rinsed with cold, clean water.
  • Before the second last rinse a disinfectant (chlorine) can be added, if needed (coloured ducts may lose some of their colours when disinfected).
  • Do not add fabric softener.
  • It is recommended that the ducts drip-dry, however, they may also spin-dry at low speed and be hung on a line while still moist.
  • The ducts can be tumble-dried if the exit air temperature does not exceed 60°C (tumble-drying the ducts may cause minor shrinkage).


Textile ducts made of the non-permeable DFC-0 material:

  • Are made with a dirt-repellent plastic coating and do not require cleaning from a flow-technical point of view. However, aesthetic and/or hygiene conditions may necessitate periodic cleaning.
  • The best way of cleaning DFC-0 ducts is by wiping the ducts externally using a damp cloth and standard cleaning agents that are normally used for floors, tables, etc.
  • After cleaning, the ducts should be wiped down with clean water.
  • If the inside of the ducts is very soiled the ducts should be turned inside out and swept, blown with air, or vacuumed.
  • Solvents containing chlorine must not be used under any circumstances.
  • It is possible to machine wash a DFC-0 duct, however, it may become wrinkled and lose some of its appearance (if it needs to be machine washed, the duct must be turned inside out and the machine should only be filled to 1/3 of its capacity with a max. temperature of 30°C using a delicate wash cycle).

10. How often do you need to wash textile ducts for optimal maintenance? 

To maintain optimal performance and hygiene, textile ducts should be cleaned at least once per year. Beyond annual maintenance recommendations, ideal washing intervals will vary depending on local environmental conditions, a system’s desired application, and the specific textile materials being used. Key parameters influencing how often a system should be washed include:

  • The ambient air quality, including the prefilter’s quality.
  • The system’s annual operating time in hours.
  • The air volume per square yard of fabric surface (the greater the load per surface area, the more frequently a system should be cleaned).
  • The textile material’s dust holding capacity (DHC).
  • Hygiene requirements (there may be specific hygiene requirements determining how frequently a system must be washed, for instance, in the food industry). 

11. Are textile ducts 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. Cradle to Cradle certification recognizes safer, more sustainable products made for the circular economy. In keeping with that goal,  every stitch and fiber of our textile solution is engineered with environmental impact reduction in mind.
