FAQ about duct sox

Duct sox (also called Duct Socks and Airsocks) is made from durable technical textiles designed to last for many years under normal conditions. Most manufacturers, including FabricAir, offer a wide range of warranties depending on the fabric type and application – often ranging from 5 to 15 years.

Cleaning is simple. Duct sox can be easily unzipped, removed, and machine-washed, then reinstalled after drying. This makes them far easier to maintain than traditional metal ducts, which are costly and time-consuming to clean. Regular washing helps ensure hygiene and optimal performance, especially in environments like restaurants, gyms, and food processing.
