PET Inner Core Polyester Insulated Duct

As a leading factory with 26 years of deep cultivation in the high-end HVAC industry, our PET Inner Core polyester insulated duct is designed to completely solve the airflow turbulence and fiber escape issues common in standard ducts. Since Mr. Hu Yidan founded the factory in Beijing in 1996, we have insisted on an R&D logic of "equal importance to air purity and mechanical efficiency." The core of this product lies in the use of an extremely smooth, high-toughness polyester (PET) film inner core. This mirror-like inner wall nearly eliminates all airflow friction, significantly reducing system static pressure loss and allowing your air conditioning fans to run at lower power, achieving true energy savings. Combined with 25mm eco-friendly, non-toxic white polyester cotton, we offer a 100% glass fiber-free "clean breathing" solution.

In the modern workshop of Dongyang Hu's Lida, we utilize leading domestic self-developed automated lines for production, ensuring the interlaminar composite strength of every roll reaches its peak. Our daily production capacity of 15,000 meters of insulated ducts fully supports the large-scale procurement needs of overseas distributors. Every roll of product leaving the factory must pass our "triple quality inspection red lines": from tensile modulus sampling of the PET film to real-time temperature control of the hot-melt composite process and 24-hour airtightness testing of the finished product. Choosing our PET Inner Core polyester insulated duct gives you not only high-quality ducts with ISO9001 and SGS certifications but also the 26-year manufacturing reputation of Hu's Lida.
