What is a SimpleSox System?

A SimpleSox System is a modular fabric ductwork system that is available for purchase online and provides you with the necessary components to meet your system requirements. The SimpleSox System offers unmatched versatility. Customers can easily order a Starter Kit that includes the right amount of Active Sections for their desired volume of air. Once it arrives, it can be installed with ease.

Each SimpleSox System comes with a predesigned Starter Kit, and you can purchase optional components to meet your specific airflow and layout requirements. The Starter Kits and optional components are available in five different diameters: 12", 16", 20", 24", and 28".

Optional Components

SimpleSox Systems are intended for simple, open ceiling applications using straight runs with or without 90 degree elbows. They can be used as an alternative to single wall metal ductwork and diffuser systems in traditional heating, air conditioning, and ventilation applications. SimpleSox can also be used as a replacement for insulated or double wall metal ductwork due to the porous characteristics that the material has. Typical applications are light industrial and retail, but can include many others.

SimpleSox Systems are constructed using a medium-weight, all-purpose, woven, polyester-
based, commercial-grade fabric that offers best-in-class performance and features. Available in white or silver fabric and is machine washable.
