Since 1997, Hua’ao introduced aluminum foil polyurethane composite air ducts to the Chinese market, pioneering the application of composite ducts domestically and marking a crucial step in the localization of high-end air ducts. After nearly three decades of dedicated development and technological accumulation, Hua’ao has successfully transitioned from technology introduction to fully independent production, breaking long-standing foreign technological monopolies and establishing itself as a standout representative of Chinese manufacturing in the global air duct industry.
In central air conditioning and ventilation systems, while air ducts may not be the most visible component, they are critical for indoor air quality, energy consumption, and user experience. For years, traditional galvanized iron sheet ducts with external insulation have been the mainstream choice. However, their limitations in energy efficiency, hygiene, safety, installation speed, and service life are becoming increasingly apparent.
1. Localization Leadership and Comprehensive Independent Innovation
Hua’ao, with 30 years in the air duct industry, inherits 70 years of professional production technology from Italy’s P3 company. Leveraging world-leading non-toxic, eco-friendly water-blowing foam technology and continuous independent innovation, Hua’ao has successfully localized and upgraded P3 technology. The company has grown into China’s most valued provider and service partner for air duct system solutions and a primary driving force behind the development of aluminum foil composite duct systems.
Throughout its technological journey, Hua’ao has consistently been at the industry forefront: In 2005, it participated in promoting the revision of National Standards GB50016 and GB8624, setting new benchmarks for industry safety and quality. In 2018, it led the compilation of the industry’s first technical specification white paper, promoting standardized development. By 2024, Hua’ao had fully realized the ‘Made in China’ transformation of P3 technology, establishing a comprehensive production and service system.
2. Six Key Product Advantages Defining New Industry Standards
① Lightweight & High Efficiency, Easy Installation
Weighing only 1.5kg/m² – 8 times lighter than traditional sheet metal ducts – enabling manual installation. Construction efficiency is improved by 3 times, with on-site noise elimination. Sound insulation reaches 21dB.
② Superior Airtightness, Energy Saving & Consumption Reduction
Special built-in flanges reduce air leakage to nearly zero, improving airtightness by 6 times. Thermal conductivity is just 0.022 W/m·K, offering excellent insulation. Service life exceeds 50 years, significantly reducing energy consumption.
③ Eco-Friendly & Healthy, Internationally Certified
Zero ODP and GWP. Certified by Europe’s EPD. No greenhouse gases are produced during manufacturing. Complies with multiple international environmental and energy management system standards.
④ Hygienic & Safe, Antibacterial & Mold-Resistant
Antibacterial rate exceeds 96%, with the highest grade of mold resistance. Water absorption is below 2.5%. The surface resists dust accumulation and is easy to clean, preventing secondary contamination. Ideal for high-cleanliness environments like hospitals and laboratories.
⑤ Strong Weather Resistance, Wide Applicability
Suitable for direct outdoor use without additional waterproofing. Corrosion resistance comparable to stainless steel. Water absorption ≤ 2.6%. Resistant to UV and chemical corrosion. Maintains shape under pressure from -2000 Pa to +2000 Pa.
⑥ Comfortable & Aesthetic, Excellent Noise Reduction
Significantly attenuates low-frequency noise from central air conditioning systems. Elegant appearance supports custom spraying, perfectly complementing exposed ducts and various decoration styles.
