3-Layer / 4-Layer Aluminum Foil Flexible Duct

3-Layer / 4-Layer Aluminum Foil Flexible Duct for High Temperature Exhaust, Kitchen Fume Extraction, UV Printing and Acid/Alkali Air Ventilation

Product Description
Our 3-layer / 4-layer aluminum foil flexible duct is specially designed for demanding ventilation and exhaust applications involving high temperature air, oil fumes, chemical exhaust, and industrial ventilation systems.

Constructed with multiple layers of reinforced aluminum foil, this duct provides enhanced durability, flexibility, and resistance to heat, grease, moisture, and mildly corrosive air. It is widely used in commercial kitchen exhaust systems, telescopic fume extraction, high temperature air transfer, UV printing exhaust, and acid/alkali ventilation applications.

The flexible structure allows easy installation in confined spaces and convenient connection to fans, exhaust hoods, ventilation units, and industrial equipment. Diameter can be customized from 32 mm to 600 mm, and length can be produced from 1 m to 30 m according to project requirements.
