A fabric air duct is a type of air duct system that is made from a flexible, textile-based material. These ducts are typically made from materials such as polyester, nylon, or a blend of synthetic fibers. They are designed to be lightweight and easy to install, and can be used in a variety of HVAC systems.

Fabric air ducts are often used in commercial and industrial settings, as well as in residential applications. They are flexible and can be easily shaped to fit into tight spaces, making them a good choice for retrofit projects or for new construction where space is limited. They can also be used in mobile or portable air conditioning units and can be insulated to reduce heat loss or gain.

One of the main benefits of fabric air ducts is that they are relatively easy to clean and maintain. They can also be treated with fire-retardant chemicals to increase fire safety. Some fabric ducts also have a UV-resistant coating that helps to prevent the growth of mold and mildew, which can be a common problem with traditional metal ducts

Fabric ducts work by using air pressure to force air through the ducts, which are made of a permeable fabric material. The fabric allows air to pass through it, while still providing a structure for the duct. The air is distributed through the ducts by a series of diffusers or nozzles, which can be adjusted to control the flow of air. The fabric material used in fabric ducts is often made of a fire-resistant material and can be cleaned easily, making them a popular choice for commercial and industrial buildings.
