Introduction of aluminum foil air duct.

Aluminum foil air duct is made of stretched pure aluminum foil, which is tightly clamped by spiral continuously. Because aluminum has oxidation properties, it is generally covered with a layer of glue during production to isolate the oxidation reaction between aluminum and oxygen in the air.

The aluminum foil air duct is mainly used for air duct ventilation at the end air supply stage on the fresh air system.

The thickness of the aluminum foil duct is generally between 0.08 and 0.2MM. According to the size of the spinning device, it can theoretically make aluminum foil air pipes of infinite caliber. However, according to the actual application, the general inner diameter is within the range of 60 to 200MM, and the length is within 10 meters.
