The “big fabric bags” customers call cloth ducts, bag ducts or fiber fabric ducts are exactly this family of fabric air ducts — also known as Sox ducts in the industry. When combined with insulation materials, they are called insulated fabric ducts, also known as insulated Sox ducts or rubber-plastic fabric ducts, collectively referred to in the industry as non-metallic composite flexible fabric duct systems. RyboTex (Nantong) focuses on non-metallic composite flexible fabric duct systems, with a complete product family covering the full spectrum of air distribution needs. We provide free duct selection and design development, with fabric duct pricing customized per project. Welcome to inquire...

InsulTex Insulated Duct Series

What customers call insulated duct or thermal insulation duct is this series. Designed for central air conditioning main ducts and air supply systems requiring thermal insulation and anti-condensation performance. By thermally fusing a composite rubber/aerogel insulation layer with fiber fabric, it completely resolves the issues of cumbersome installation, susceptibility to damage, and condensation dripping found in traditional metal ducts with external insulation.

  • Ultra-low thermal conductivity: Excellent insulation performance for energy savings and emission reduction
  • Integrated anti-condensation: Closed-cell foam structure blocks water vapor penetration
  • Lightweight structure: Minimal roof loading, ideal for large-span steel structure workshops
  • Modular zipper connection: Fast and efficient on-site assembly
  • HS High-Seal / RA Return-Air series: See dedicated cards below
Thermal conductivity≤ 0.018 W/(m·K)

InsulTex HS High-Seal Duct Series

What customers call high-airtightness, low-leakage insulated duct is exactly the InsulTex HS high-seal series. Building on the InsulTex insulated series with an enhanced sealing system: double-layer sealed zippers with an extrusion seal at every duct connection, plus an anti-leak cover that presses tight against the zipper under internal duct pressure — the higher the pressure, the tighter the seal — eliminating air leakage and heat loss at the source.

  • Double-layer sealed zipper: Extrusion seal on both inner and outer layers, no gap leakage
  • Anti-leak cover: Self-tightening under pressure, tighter seal as pressure rises
  • High airtightness, low leakage: Far lower leakage than traditional flanged ducts
  • Energy saving: Reduced leakage losses, lower fan energy consumption
Sealing systemDouble-layer sealed zipper + anti-leak cover
Leakage classHigh airtightness, superior to traditional flanged connections
Fire ratingClass B1 flame retardant
ApplicationsLow-dew-point supply air, constant temperature/humidity workshops, high-static main ducts

InsulTex RA Return-Air Duct Series

What customers call return-air duct is exactly the InsulTex RA return-air series. Return-air systems run under negative pressure for long periods, and fabric ducts without an insulation layer deform noticeably under negative pressure; InsulTex RA features a built-in insulation layer and support skeleton/keel to keep a round cross-section without collapsing, while its sealed structure prevents outside air from infiltrating and protects return-air quality.

  • Return-air specific: Built-in insulation layer + support skeleton/keel keep a stable cross-section under negative pressure
  • Negative-pressure resistance: Uninsulated return ducts deform noticeably; RA adds structural strength
  • Leak-resistant seal: Prevents outside air infiltration under negative pressure
  • Condensation-resistant insulation: Closed-cell insulation blocks temperature-difference condensation
Operating conditionNegative-pressure return-air systems
Insulation layerComposite rubber/aerogel thermal insulation layer
Support structureBuilt-in support skeleton/keel maintain round cross-section
ApplicationsCentral return-air systems, constant temperature/humidity workshops, underground spaces

StandTex Support Duct Series

What customers call support duct is this series. Maintains an attractive rounded shape even when the system is off, solving deformation issues from frequent start-stop cycles. Built-in polymer support ribs/ring mechanism prevents collapse when powered down, ensuring high visual appeal.

  • No collapse when off: Built-in support ribs/ring mechanism maintains rounded shape
  • Suited for frequent start-stop: Perfectly solves deformation in intermittent operation scenarios
  • High aesthetics: Always maintains a perfect circular cross-section for visual consistency
  • Maintenance-free: Support structure requires no maintenance, long service life
Support methodBuilt-in polymer support ribs/ring mechanism
Cross-sectionPermanent round (no deformation when off)
ApplicationsIntermittent operation spaces, high-standard aesthetic spaces

CleanTex Cleanroom Duct Series

What customers call cleanroom duct or clean air duct is this series. Surface-treated with antimicrobial, dust-repellent, and anti-static finishes for pharmaceutical, electronics, and food production workshops. Anti-static, antimicrobial, and low-particle-generation properties meet GMP and stringent cleanroom standards.

  • Anti-static treatment: Surface resistance stabilized at 10^6~10^9 Ω
  • Antimicrobial: Nano-silver ion technology, antibacterial rate ≥ 99.9%
  • Low particle generation: Meets ISO Class 5 and above cleanliness requirements
  • Modular quick-detach: Fast disassembly for cleaning, meeting GMP validation requirements
Cleanliness classISO Class 5~8 / GMP Grade A~D
