History of Fabric Air Ducting
Fabric air ducting has been in use since 1948. In 1963 Fabric air tubing was developed for heating and ventilating in the greenhouse industry with only one diameter of tubing available. Holes were punched manually with a rubber mallet. Since then, the tubing has been diversified considerably in size, shape, and application. Not only is it still used in greenhouses, but is now used for a wide range of manufacturing and industry applications, as well as commercial, retail, office and school environments.
Hero FabriDuct™ products are Polyester fabric supply air diffusion systems, operating under positive pressure. The diffusion occurs through any combination of permeable and non-permeable fabrics, and /or strategically designed linear slots. Hero Fabriduct™ systems are available in round, “D” shape, or quarter-round duct configuration. These systems are designed to provide uniform air distribution in commercial, industrial, public warehouse environments and homes. When tested in accordance with ASTM E-84, these Polyester fabrics have a flame spread index of less than 25, and a smoke developed index of less than 50. Hero FabriDuct™ fabric products are limited to use in systems with a maximum positive design pressure equivalent to 3.1 inches of water column, a maximum operating velocity of 2,000 feet per minute, and a temperature range of 0° F to 250°F (-18°C to 121° C).
