Description
Variable Swirl Diffuser (VSD) is a device installed at the end of duct-work to distribute conditioned air in a “swirl pattern” throughout a room using adjustable blade angles. “Swirl pattern” distribution is ideal for mixing conditioned air with existing room air, resulting in enhanced indoor air quality and helping to achieve air change effectiveness measure. VSD units are designed for high induction requirements: specifically room heights between 13’ (ft) to 33’ (ft).
