Designed, tested and produced to meet your specific needs.
As a company specialized in air distribution in public transport vehicles, we are able to come up with a unique textile air ducts tailored to any type of vehicle. In-depth knowledge of the field of HVAC, high flexibility in design or savings in transport and installation, these are just some of the benefits of our solution. Read more about our products.
The complex solution for the even air distribution in the interior of railway vehicles. The design of the whole air duct is individual. Both hot and cold air can be distributed using one duct with more chambers.
• Fire resistance EN 45545-2 HL2 / HL3
• Insulated / partially insulated / non-insulated variant
• Low weight, fast installation, easy maintenance
Low-weight interior air ducts of various cross-sections and shapes. It can be used as a connecting air duct or as an air duct with an air distribution function. Smart solution for confined spaces in trams, trains, buses, etc. Various outlets and distribution elements can be designed.
• Fire resistance EN 45545-2 HL2 / HL3
• Insulated / partially insulated / non-insulated variant
• Low weight, fast installation, easy maintenance
Special air duct solutions for complicated spaces in the driver's cabin. Almost any shape can be produced - outlets, arcs, adapters, etc. The air distribution is designed according to customer needs and can also be tested in our lab on mockup. Air regulation on air duct outlets using a perforated layer of fabric is also possible.
• Fire resistance EN 45545-2 HL2 / HL3
• Insulated / partially insulated / non-insulated variant
• Low weight, fast installation, easy maintenance
Interior flexible compensators of various shapes and sizes from straight ones to complicated adapters. Different types of metal flanges are possible. Connection of conventional rigid air distribution systems. Eliminate noise transfer and compensate neighboring components' tolerances and shifts.
• Fire resistance EN 45545-2 HL2 / HL3
• Insulated / non-insulated variant
• Low weight, fast installation, easy maintenance
Lightweight interior flexible air duct hoses with inside spring steel spiral. Suitable e.g. as an element of the air distribution system of the driver's cab or as flexible air ducts leading warm air from the ceiling ducts to the outlets at the floor of the rolling stock.
• Fire resistance EN 45545-2 HL2 / HL3
• Insulated / non-insulated variant
• Wide range of diameters and cross sections
Interior air duct where the connection is ensured by textile straps with a buckle. The connection can be secured with sewn-in velcro. Different shapes and sizes are possible. Various types of attachments or reinforcement for keeping the shape can be added.
• Fire resistance EN 45545-2 HL2 / HL3
• Insulated / non-insulated variant
• Low weight, fast installation, easy maintenance
These exterior fabric compensators are very durable and suitable for the outdoor environment. They are used to connect HVAC systems ducts on the vehicle's roof, compensate the tolerances and eliminate noise transfer. They are connected with aluminum or stainless steel flanges. PRODUCT SHEET

• Insulated / non-insulated variant
• UV-resistant, waterproof, outdoor temperatures resistant
An exterior compensator with more chambers made of very durable materials. They are used to connect HVAC systems ducts on the vehicle's roof, compensate the tolerances and eliminate noise transfer. They are connected with aluminum or stainless steel flanges. PRODUCT SHEET
• Fire resistance EN 45545-2 HL2 / HL3 / NFPA 130
• Insulated / non-insulated variant
• UV-resistant, waterproof, outdoor temperatures resistant
A wire-reinforced interior fabric air duct for exposed points of the vehicle joints (gangways). It is very durable and flexible. It keeps the cross-section the same while bending. Possibility of different attachments on the sides and along the air duct.
• Fire resistance EN 45545-2 HL1 / HL2 / HL3
• Excellent flexibility
• Low weight, fast installation, easy maintenance
The wire-reinforced interior fabric gangway air duct is specifically designed for exposed points of vehicle joints (gangways) for air conditioning and ventilation systems. It offers durability and flexibility, maintaining a consistent cross-section even when bent. With its multi-chamber design, this air duct allows for the distribution of both hot and cold air. Additionally, it provides the flexibility to attach various components on the sides and along the length of the duct to meet specific attachment requirements.
• Fire resistance EN 45545-2 HL1 / HL2 / HL3
• Excellent flexibility
• Low weight, fast installation, easy maintenance
• Most lightweight HVAC ducting technology on the market
• Up to 90 % weight savings compared to metal alternative
• Our most commonly used fabric weighs only 200 g/m2
• Deep knowledge of airflow calculations
• Uniform air distribution in the vehicle interior
• Great flexibility and customization of airflow
• Expert component optimization using 3D CAD software
• Cost-saving solutions through customized adjustments
• Freedom in the design of complex duct shapes
For perfect functionality, it is necessary to attach the diffusers to the air-handling unit and fix it into the vehicle structure with suitable fixtures. For this purpose, we use sewn-in enlarged strips, which are slid into c-profiles fixed to the structure.
Other smart options include fabric or stainless straps equipped with fasteners, as well as Velcro, Velcro loops, or metal flanges. We always design the attachment system to achieve maximum speed and simplicity during the installation and removal of the air duct.
