Focused on Textile: Innovative HVAC Air Ducts for Railway Vehicles

The world-famous Techtextil trade fair defines the trends for modern technical textiles, leading to lighter, more functional, and more sustainable fabrics (

For almost 30 years, Prihoda Group (AirDIV is part of Prihoda Group) has tirelessly pursued the optimal combination of weight, functionality, quality, sustainability, and safety in the realm of textile ducts.

In the past, our company’s ducts were bulky, weighing in at 400 g/m2 or more, which proved to be far from ideal. However, our relentless commitment to innovation has led to development of textile ducts that now weigh a mere 200 g/m2, setting new industry standards.

This development benefits customers in the rolling stock segment, where weight is a key parameter to be monitored. Below are some of the basic material properties of the technical textiles that characterize the textile air duct systems for railway HVAC systems:

Fire Safety

Our fabrics meet the most demanding HL3 standards according to the EN45545-2 standard for R1 materials. Thanks to this, it is possible to use them for air duct systems in any railway vehicles such as subways, trams, sleeping cars, or high-speed trains.

Lightweight Design

Reducing the weight of our textile ducts offers several advantages for the rolling stock industry. It translates into lower transportation costs, enabling quicker and more straightforward product handling. Installing our textile ducts becomes a breeze, reducing physical strain on workers and lowering maintenance costs.

Enhanced Functionality

Our textile ducts undergo an antibacterial treatment that effectively prevents the survival of bacteria on the fabric, ensuring a hygienic environment within a rolling stock. We’ve also incorporated an antistatic treatment to eliminate the common issue of static electricity, often encountered with polyester materials.

Uncompromising Quality

AirDIV takes pride in delivering textile ducts constructed from solid, endless fibers that are virtually indestructible during normal operation. Based on our extensive experience, our textile ducts have maintained their functional properties for over 30 years, reflecting our unwavering commitment to quality.

Sustainability at the Core

Lighter textile ducts offered by AirDIV significantly reduce the carbon footprint across their lifecycle. This translates to less CO2 emissions during production, transportation, and eventual disposal, aligning with the industry’s sustainability goals.
