aluminum foil for flexible air ventilation system exhaust dust vent hose sleeve pipe

Products Description
The aluminum foil air duct is made of stretched pure aluminum foil, which is continuously and tightly clamped by spiral. Due to the oxidation property of aluminum material, a layer of glue will be coated during production to isolate aluminum material and oxygen in the air to produce oxidation reaction.Aluminum foil air duct is mainly used to ventilate with air duct in the end air supply stage of fresh air system.


The product thickness is generally between 0.08 and 0.2mm. According to the size of spinning tools, it can theoretically be used as an infinite diameter aluminum foil air duct. However, according to the actual application, the inner diameter is generally within 60-200mm, and the length is within 10m.
