[Beijing, 2026.1.15] – Fanryntech, a leading innovator in air movement and ventilation solutions, proudly announces its flagship Aluminum Semi-Rigid Duct, engineered to meet the rigorous demands of modern heating, ventilation, air conditioning (HVAC), and various industrial systems. This duct combines the durability of rigid ducts with the installability of flexible ones, setting a new benchmark for performance and safety.

Constructed from high-grade, soft aluminum foil with a unique spiral-wound, interlocked seam, the duct is inherently non-combustible, eliminating fire hazards and ensuring compliance with stringent safety regulations. Its self-supporting structure often requires minimal fittings, significantly reducing installation time and labor costs.

Our Aluminum Semi-Rigid Duct is designed from the ground up to deliver reliable airflow, withstand extreme conditions from -25°C to +300°C, and provide peace of mind with its flame-retardant properties. It's the intelligent choice for engineers and specifiers who cannot compromise on quality."

• Superior Safety: Made from non-flammable aluminum, it releases no toxic fumes at high temperatures, making it ideal for demanding environments.

• Exceptional Flexibility & Strength: Features a 1:3 extension rate and robust corrugated design (3, 5, or 9 spirals) to navigate tight spaces without kinking, while handling working pressures up to 2500 Pa and air velocities up to 30 m/s.

• Broad Application Range: Perfect for low-to-medium pressure air conditioning, general ventilation, boiler systems, chimney liners, and specialized industrial exhaust.

• Logistical Efficiency: Available in standard lengths of 1.5m, 3m, and 6m, with diameters ranging from 2 inches (50mm) to 20 inches (500mm), facilitating easy project planning and integration.

The product is now available for order and sampling. For HVAC contractors, mechanical engineers, and industrial facility managers seeking a durable, safe, and efficient ducting solution, Fanryntech's Aluminum Semi-Rigid Duct represents a significant upgrade.
