We offer a quality solution

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


Our HVAC 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.


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 HVAC 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.


The materials used for air distribution 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.

  • strength and durability
  • fire resistance
  • abrasion resistance
  • easy to clean
  • antibacterial
  • EN 45545 R1 HL2 & HL3 certified


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
  • tailor-made
  • complex shapes
  • reliable solution
  • CFD simulations
  • long service life
