We offer a quality solution

Based on years of experience and testing, we provide reliable fabric air duct systems for air distribution in train, tram and metro coaches and driver cabins. We can also resolve air distribution in buses, ships, aircraft, military, and other special vehicles.

PRODUCTS & APPLICATIONS

Our fabric air ducting systems are particularly suited for public transport vehicles. We can design and deliver air ducts for passengers' saloons and drivers' cabins of metros, trams, and trains, but also for buses, and military and other vehicles including ships. Our fabric air ducts are the most lightweight solution on the market. Installation is extremely quick and easy in comparison to traditional metal or rigid composite air ducts. Thanks to their low weight and compactness, they save significant installation, transport and storage costs.

APPLICATIONS PRODUCTS

SERVICES

We provide solutions of the highest technical standard and deliver our clients support and expertise in every stage of the project. We are not mere air duct suppliers, but we also cooperate with our clients to develop specific tailor-made air conditioning solutions. We provide support in 3D modeling and making drawings. We design the airflow in the vehicle using our own software and also Fluent CFD software to ensure the best possible ventilation of the space. We test prototypes in our laboratory and measure all needed values.

MATERIALS

The fabrics used for air ducts have to meet the highest demands with regards to quality, technology, sustainability as well as certification. We only use materials that meet these criteria, most of which have been especially developed for air distribution systems in vehicles.

  • EN 45545-2 R1/HL3 & NFPA 130 certified
  • strength and durability
  • fire resistance
  • abrasion resistance
  • easy to clean
  • antibacterial
MATERIALS

AIR DISTRIBUTION

All our air duct systems are tailor-made to the customer’s precise requirements. Fabric air ducts are dimensionally adapted to spatial limitations, and we can also handle very complex shapes. Despite the limitations, we are still able to provide perfect air distribution to ensure a comfortable indoor environment for passengers.

  • uniform air distribution
  • custom-made airflow
  • variety of air outlet methods
  • removing air deflection
  • no additional regulation needed
  • CFD simulations

Main problems we solve

Check some of our references

➀ EXCESSIVE WEIGHT

Heavy rigid ducting (metal or composite) adds weight, burns energy, and eats into payload.

➁ COSTLY INSTALLATION

Rigid ducting is heavy and awkward to fit — driving up labor cost and delaying delivery.

➂ POOR AIR DISTRIBUTION

Hot and cold spots mean passenger complaints after the vehicle's already in service.

What we offer

Explore our product portfolio

➀ LIGHTEST DUCT ON THE MARKET

Up to 90% lighter than sheet metal and up to 60% lighter than composite ducting — often eliminating hundreds of kilograms per vehicle.

➁ FASTEST INSTALLATION

Up to 90% less installation time and 60% less labor than rigid ducting — turning a multi-person job into a task two installers can handle with ease.

➂ PRECISE, EVEN AIRFLOW

Our ducts routinely pass independent climatic chamber comfort testing to EN 13129 (main line) and EN 14750 (metro, tram, regional).

➃ DESIGN EXPERTISE, ZERO RISK

We handle everything from concept to mockup — 3D CAD models, drawings, airflow calculations, CFD simulation, and prototype testing.

➄ RICH EXPERIENCE

30+ years of engineering know-how — solving airflow challenges other suppliers haven't yet encountered.
