Product Description Product DescriptionRound HVAC Spiral Air DuctsRound Spiral Ducts are essential components in HVAC systems, providing efficient and reliable air distribution. Made from stainless steel or galvanized steel, these air ducts offer excellent durability and corrosion resistance.The spiral structure promotes smooth airflow with minimal pressure loss, making them ideal for both residential and commercial ventilation applications. Round Spiral Ducts, commonly used in air conditioning and ventilation systems, are valued for their high structural strength and rigidity.GFI HVAC Main Structural styles For Spiral Duct SupplySR (Smooth Interior Surface)Features a smooth interior surface, resulting in minimal friction loss and optimal airflow.SR2C (Corrugated Exterior with Reinforcements)This design includes external corrugations with stiffeners, which further enhance the structural strength of the duct.GFI HVAC ensures each duct is precisely formed and tightly sealed to minimize air leakage and maximize system efficiency.
