FabricAir’s VarioDuct is a highly engineered solution for most commercial building applications that provides both uniform heating and cooling out of the same ceiling-hung fabric duct, the company notes. The motorized damper actuator automatically switches a duct run between bottom or top air dispersion for uniform heating and cooling temperature gradients. This uniformity from the same duct run is made possible with a full-length internal membrane that’s positioned via a mechanized damper to disperse either warm air through its bottom hemisphere or cool air through its top hemisphere. It is available in any length and in diameters ranging from 16” to 32” diameter (400 to 800-mm).
