Gangway Fabric Air Ducts

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 HL2 / HL3
• Excellent flexibility
• Low weight, fast installation, easy maintenance

Gangway Fabric Air Ducts

Gangway Fabric Air Ducts
(Multi-Chamber)

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.
