For air dispersion application, there are mainly two typical materials, metal and fabrics, traditional metal duct systems discharge air through side-mounted metal diffusers. The air is directed to specific zones resulting in less efficient mixing of air in the occupied space and often causing drafting and hot or cold spots; while the fabric air dispersion has uniform holes along the entire length dispersion system, providing consistent and uniform air dispersion in the occupied space, Uniform air dispersion means better air mixing which brings better performance for those areas need ventilation.
About textile ventilation ducts
Light weight, noise absorption, hygienic material, easy to maintain, all these features have accelerated the promotion of the fabric air dispersion system in the past decade. As a result, the demand of fabric air dispersion has been increased, which challenged the production efficiency of fabric air dispersion factory. Precise and high-efficiency of laser cutting can simplify the procedures of processing fabric.
The air dispersion fabric is definitely better solution for ventilation while it is a big challenge to make the constant holes along the 30 yards long or even longer fabrics and you have to cut the pieces out besides for making the holes. Only laser can realize this process.
CO2 laser system is setting new standards especially where the exact cutting and fast perforating of these technical textiles is concerned.
