Duct sox
Duct sox for Indoor Comfort
Duct sox (also known as fabric air ducts or duct socks) is built around four main elements: profile, fabric, flow model, and suspension. These parts can be combined in multiple configurations, allowing the system to be tailored to the exact demands of any project.
By choosing the most suitable setup for each component, our expert team creates custom duct socks solutions that guarantee efficient air distribution and a comfortable indoor climate, even in the most complex spaces.
All duct sox/socks systems are manufactured in advanced facilities that meet globally recognized certifications, including ISO 9001, ISO 14001, Oeko-Tex® Standard 100, UL 2518, EN 15725, and full REACH compliance. Additionally, every product is supported by an Environmental Product Declaration (EPD), ensuring transparent, verified data on environmental impact across its life cycle.

FAQ about duct sox
What are the main benefits of using duct sox instead of traditional metal air ducts?
Duct sox provide even air distribution, reduce drafts, and support better thermal comfort. They are lightweight, quick to install, machine washable, and corrosion-resistant – making them ideal for humid, hygienic, or complex environments where metal ducts may fall short.
Is duct sox suitable for use in regulated environments like healthcare or food processing?
Yes. Many duct sox are made with antimicrobial, flame-retardant fabrics and comply with hygiene and safety standards. Their removable, washable nature makes them a practical choice for industries with strict cleanliness and air quality requirements.
How does duct sox improve energy efficiency in HVAC systems?
By reducing pressure losses and optimizing air distribution, fabric duct sox can help HVAC systems operate more efficiently. Studies show that systems using air socks can reduce energy use by 15-40%, depending on the application and system design.
How long does duct sox last, and what is the typical warranty?
Duct sox 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.
Where is duct sox most commonly used?
Duct sox is versatile and widely used in gyms, sports arenas, offices, restaurants, retail spaces, warehouses, healthcare facilities, and food processing plants. Their adaptability, hygiene, and design flexibility make them suitable for both commercial and industrial applications.
How easy is it to clean and maintain duct sox?
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.
