What we offer

Explore our product portfolio

➀ The most lightweight air ducts on the market

Textile air ducts can save up to 90% weight in comparison with sheet metal ducting and also provide significant weight savings compared to composite air ducts. They can be easily handled and they represent a minimal load for vehicle structures.

➁ Fast installation

The installation of textile air ducting in vehicles is very easy and fast. It will take you only a fraction of the time you would need to assemble rigid (metal, composite) ducting.

➂ Airflow based on given requirements

The custom-designed combination of a large number of distribution elements provides the required, usually even, flow of air through a vehicle’s passenger saloons or driver‘s cabins.

➃ Comprehensive support

We offer comprehensive free technical support, such as 3D CAD modeling, preparation of drawing documentation, designing of air distribution elements on the air duct, and airflow calculations.

➄ Rich experience

With decades of experience in textile air ducts, we've developed unique expertise in designing effective solutions for vehicles. We've encountered and overcome numerous challenges, refining our products to ensure optimal performance and long-lasting reliability.
