Product Advantages
- Superior Thermal Insulation: The 3mm composite middle layer acts as an effective thermal barrier, significantly reducing heat gain in cooling mode and heat loss in heating mode. This improves overall HVAC efficiency, lowers energy costs, and prevents condensation.
- Durable Triple-Layer Construction: Built to last with a 0.55mm thick PVC reinforced outer coating (abrasion-resistant), a 3mm insulating core, and a 0.4mm thick PVC mesh inner liner. This structure ensures longevity, puncture resistance, and smooth airflow.
- Reinforced Spiral Steel Wire: Embedded high-tensile steel wire (3.5mm diameter) provides structural integrity, excellent shape retention, and crush resistance. It allows the duct to be bent and routed through tight spaces without kinking or collapsing.
- Flexible & Easy to Install: The 18cm wire pitch (varies by diameter) offers the perfect balance of flexibility and support. Lightweight and easy to cut, it saves significant installation time and labor compared to rigid metal ducts.
- Secure & Airtail Connection: Features 10cm flexible cuffs at both ends without wire, paired with sturdy drawband fasteners. This ensures a tight, secure, and leak-free seal when connected to register boxes, diffusers, or other duct components.
- Versatile Size & Color Range: Available in a comprehensive diameter range from 4 inches (100mm) to 59 inches (1500mm) and standard lengths of 3m or 10m. Choose from multiple colors (Yellow, Grey, White, Blue, Red, Black, Green) for coding, matching decor, or meeting specific job site requirements.
- Protective Outer Wrap: The outermost layer is protected with a PVC wear-resistant strip, enhancing durability against friction and abrasion during and after installation.
Application Scenario
- Residential HVAC: Connecting central air conditioners, furnaces, and heat pumps to vents in homes and apartments.
- Commercial Ventilation: Ductwork for office buildings, retail stores, and restaurants for supply/return air.
- Industrial Exhaust & Fume Extraction: Suitable for moving air in workshops, factories, or laundry rooms (verify temperature rating for specific applications).
- Attic & Crawl Space Installations: Ideal for retrofit projects where space is constrained and routing around obstructions is necessary.
- Temporary Heating/Cooling: Perfect for construction sites, event tents, or temporary facilities.
Frequently Asked Questions
1
Is this flexible duct suitable for both heating and cooling?
Absolutely. Its core design is as a flexible duct for heating and cooling. The integrated 3mm insulation layer is effective for both high and low-temperature air, reducing energy loss and preventing condensation year-round.
2
How do I choose the right diameter?
The diameter must match the outlet size of your HVAC equipment and the requirements of your system design. Common residential sizes are 6", 8", 10", and 12". Always consult your system's design plans or a qualified HVAC technician.
3
How do I connect and seal it?
Slide the wire-free end cuff over the rigid duct or register box neck. Then, tighten the provided metal drawband fastener securely with a screwdriver or drawband tool to create an airtight seal. Duct mastic or foil tape can be added for an extra seal if required by local code.
