We sprayed strong "rust agent" directly on the surface of the two air ducts to simulate the environment of extreme humidity and corrosion. Then, stand still for 1 hour.
β° After 1 hour, the result is amazing:
β
A3 aluminum foil composite air duct: no obvious rust on the surface! With water, it is clean and shiny as new, and there is no rust residue at all. This corrosion resistance is amazing! πͺ
β Traditional tin air duct: there are obvious traces of rust on the surface, and the yellow-brown rust spots are clearly visible. If this is installed in the ceiling, if it takes a long time, it will not only rot and leak air, but also rust slag may be blown into the air!
π‘ What does this mean?
Your ventilation system, if it is made of traditional iron, is rusting and aging from the inside in the kitchen, basement, coastal area or humid environment! This will bring:
β‘οΈ Air quality decreases (rust particles diffuse with the air)
β‘οΈ The life of the air duct is shortened, and the air leakage increases energy consumption.
β‘οΈ High cost of later replacement and maintenance
The A3 aluminum foil composite air duct, with its special composite materials and surface treatment technology, fundamentally resists rust, ensures the long-term stable operation of the system, and protects the purity of indoor air. π‘
Choose once and rest assured for decades! Don't pay for the invisible hidden dangers anymore!
