Nanosox- N series

Nanosox is a flexible air dispersion system for the HVAC/R industry made of special high-tech fabric with PFPC (Precise fabric multi-permeability control) core technology. It is able to replacing traditional air ducts, air valves, diffusers and insulation.See more…

IRR™(Internal Retention Ring)-N series

IRR™ (system utilizes a strong, yet light weight specialty material to construct the internal support ring. It helps the soft fabric air dispersion system retain inflated look without static pressure. The system is extremely light weight, and adds very little extra installation time. The patent pending sew-in pocket construction makes the system very flexible and easy to wash. Additional tension cables at the end of each straight section ensure fabric between rings is kept round and taut when deflated.See more…

URR™ (Uniform air velocity, Reducer, Retention)-N series

URR™ is a uniform velocity air dispersion system with Internal Retention Ring. By perfectly integrating IRR™ (Internal retention ring system) with UR™ system (uniform velocity air dispersion system), URR™ system remains round and taut when deflated, absorbing all the advantages of both products, such as more even airflow system, better aesthetic, easier to produce, lighter weight, convenient for packaging and transportation, simple installation, washable, long service life, higher strength and economical.See more…


DiffuSox™ is made of metal frame and highly permeable fabric, the air dispersion surface attach to the metal frame via Velcro, connecting to metal inlet via square to round fitting and detachable inlet. The design of DiffuSox™ can be customized in view of its application.See more…

UFSOX-N series/I series

UF™ system is a specialty fabric duct system that is installed underneath raised access floor space which provides an air highway to guard against thermal decay and achieve optimum air distribution.See more…

Returnsox™-N series/I series

Made of high-strength nano-alloy material, ReturnSox™ utilize exclusively-owned patented internal support frame to maintain the flexible air duct in rectangle shape and return air under negative pressure. Matching with air vents, air dampers, Returnsox™ is a replacement of traditional return air duct with cable suspension system to install on site. According to the material, there are two types: DurkeeSox Returnsox and InsuSox Returnsox.See more…
