We offer a quality solution

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


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
  • machine-washable
  • antibacterial
  • EN 45545 certified


All our products are tailor-made to the customer’s precise requirements. Air ducting is 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.

  • tailor-made products
  • even air distribution
  • precise calculations
  • CFD simulations
  • functional solution
  • proven solution


Our HVAC air distribution systems are particularly suited for public transport vehicles. We can design and deliver air distribution systems for passengers' saloons and drivers' cabins of metros, trams, and trains, but also for buses, and military and other vehicles. They are very lightweight, so installation is quick and easy. Thanks to their low weight and compactness, they save significant transport and storage costs. In addition, they can be perfectly cleaned by washing them.


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 analyze 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.
