High toughness and compressive resistance: Aluminum foil ducts usually use a high-quality aluminum foil and steel wire spiral composite structure, featuring good toughness and compressive resistance. They are not easily deformed or crushed when bent during installation, maintaining the integrity of the ventilation cross-section and ensuring smooth smoke exhaust. Flexible installation and strong adaptability: The duct body is soft and bendable, able to meet the installation needs of different kitchen layouts. It can bypass beams, cabinets, and other obstacles, connecting range hoods and smoke outlets arranged non-linearly, making installation and adjustments relatively convenient. Sealed leak-proof connection design: The duct ends are equipped with elastic sealing rings or clamp devices, forming a good seal when connected to the range hood and duct interfaces. This helps reduce smoke leakage, improve exhaust efficiency, and prevent oil stains from contaminating the ceiling. Wide compatibility with standard interfaces: Standard interface sizes can fit most mainstream brand range hood outlets. Multiple diameter options are available, allowing users to flexibly choose according to the outlet size of their own range hood.
