Key Features of Insulated Flexible Air Duct D100
Insulation Structure and Reinforced Aluminum Layer
The D100 insulated flexible air duct consists of three main layers: an inner flexible aluminum core reinforced with spiral steel wire, a middle layer of 25mm thick fiberglass insulation (density 22kg/m³), and an outer white foil jacket. This structure provides flexibility, heat resistance, and sound insulation.
The multi-layer soft aluminum core offers high strength, good elasticity, and easy bending during installation.
The fiberglass insulation helps retain temperature inside the duct and minimizes heat loss.
The outer foil layer reflects heat, resists moisture, and meets ROHS 17ZGC0323001RR standards.
Thanks to this structure, the duct operates stably from -30°C to 150°C for long-term performance.
Superior Flexibility and Airtight Performance
The airtight capability of the D100 insulated flexible duct is enhanced by its spiral steel reinforcement, preventing deformation when bent or stretched.
Longitudinal tear strength reaches 250N (ASTM E345).
Working pressure >2500Pa for 2 hours without air leakage.
Fire-resistant inner core meets ASTM D635 and UL 94, helping limit toxic smoke spread during fire incidents.
Flexible Installation for Any Space
With a bending radius of only 0.54 × diameter (≈54mm for D100), the duct can:
Be installed in tight spaces, corners, false ceilings, or obstructed areas.
Connect easily with round, oval, or rectangular fittings.
Lightweight design simplifies transport and installation without increasing structural load.
Efficient Thermal and Acoustic Insulation
More than 30% of energy loss in HVAC systems can occur through uninsulated ducts. The D100 insulated duct helps maintain stable air temperature:
25mm fiberglass layer with low thermal conductivity minimizes heat transfer.
Cold air stays cold and warm air stays warm throughout the duct path.
Insulation also reduces airflow noise, ideal for hotels, offices, hospitals, and meeting rooms.
Energy Saving and Cost Reduction
Reduces load on air conditioning and heating systems.
Saves 10%–20% energy in large HVAC systems.
Minimizes maintenance thanks to stable airflow and pressure.
Although initial cost is higher than non-insulated ducts, long-term operating savings are significant.
Safe and Non-Toxic
ROHS compliant – free from lead, mercury, cadmium, and harmful substances.
Environmentally friendly and does not release toxic gases during fire.
Clean, non-irritating, and dust-free during installation.
Ideal for clean environments such as shopping malls, clean rooms, food factories, and healthcare facilities.
Air Conditioning Systems
Delivers cooled air from central AC to rooms in buildings and apartments.
Fits easily inside false ceilings without structural modification.
Avoids obstacles like beams, wiring, and pipes.
Maintains airflow speed up to 30m/s.
