NUOENWEI Portable Insulated Ducting – 4″ to 59″ Flexible Air Duct for Grain Coolers, Tent AC & HVAC Systems (3-Layer Thermal Insulation)
The NUOENWEI Portable Insulated Ducting is engineered specifically for use with grain cooling units (grain chillers), spot air conditioners, portable HVAC systems, and ventilation fans. Its integrated 3mm thermal insulation layer effectively reduces condensation and energy loss, ensuring that cold or warm air reaches the target zone at near-original temperatures.
Key engineering highlights:
-
Outer layer: 0.55mm PVC reinforced coated fabric (abrasion & weather resistant)
-
Middle layer: 3mm closed-cell thermal insulation foam
-
Inner layer: 0.4mm PVC fabric with smooth finish (reduces air resistance)
-
Structural reinforcement: Helical spring steel wire (diameter varies by duct size)
-
Extra protection: External PVC wear-resistant strip over the wire spiral
-
End connections: 10cm soft connector section (no wire) on both ends, with tightening clamps for quick, leak-free attachment
This design allows the ducting to be compressed for storage, easily extended on-site, and connected to standard flanged outlets or round duct adapters.
NUOENWEI Portable Insulated Ducting
The NUOENWEI Portable Insulated Ducting is a professional-grade, flexible air hose designed for high-efficiency delivery of cooled or heated air in demanding temporary and semi-permanent environments. Whether you are preserving grain quality in silos, cooling large military or event tents, or extending the reach of a portable air conditioner, this insulated ducting minimizes thermal loss while maintaining superior airflow.
Made with a triple-layer composite construction (outer PVC abrasion layer, middle thermal insulation core, inner smooth PVC fabric), reinforced with a helical steel wire and an external wear-resistant PVC strip, NUOENWEI ducting combines durability, flexibility, and insulation performance. Available in diameters from 4 inches (100mm) up to 59 inches (1500mm) and standard lengths of 3m or 10m, it is the go-to choice for HVAC professionals, agricultural operators, and event organizers.

Product Advantages
- 3-Layer Thermal Insulation (3mm middle core) → Minimizes heat loss/gain, reduces condensation, lowers energy costs.
- Reinforced helical spring steel wire → Prevents kinking/collapsing, maintains round airflow channel.
- Wire-free 10cm soft ends with clamps → Easy airtight connection to any duct port.
- 0.55mm PVC outer + wear-resistant strip → Withstands abrasion on rough surfaces; protects wire.
- Smooth 0.4mm PVC inner liner → Low friction, high air velocity, easy cleaning.
- Wide diameter range 4″–59″ (100–1500mm) → Fits small AC to large grain chillers.
- Compressible (4:1 ratio) & lightweight → Saves storage space and handling effort.
- Custom colors (yellow/grey/white/blue/red/black/green) → Safety, branding, or aesthetic matching.
- UV & moisture resistant materials → Durable for temporary outdoor use.
Application Scenario
Grain Storage & Silo Cooling
Connect to grain cooler units (grain chillers) to push cold, dry air through stored grain. Prevents aflatoxin, mold, and insect activity. Insulated ducting ensures no condensation drips into grain.
Temporary Tent Air Conditioning
Large event tents, military field hospitals, or emergency shelters – run cooled or heated air from a portable HVAC unit to remote tent sections without thermal loss.
Industrial Spot Cooling
Factory workstations, control rooms, or machinery enclosures. Direct cool air exactly where needed while the AC unit stays outside.
Outdoor Camping & Glamping Tents
High-end camping setups use portable AC units with this ducting to deliver cool air silently into sleeping areas.
Agricultural Drying & Ventilation
For drying crops (herbs, tobacco, nuts) or ventilating livestock barns – the ducting withstands dust and mild chemical exposure.
Construction & Restoration Drying
Pair with a heater or dehumidifier to dry water-damaged buildings; thermal insulation keeps heat inside the duct.
Temporary Cleanrooms or Spray Booths
Supply filtered, temperature-controlled air to portable containment areas.
