The use of flexible ducts for traditional ducts can ventilate narrow areas that cannot be reached. Our air duct is composed of three layers, the first layer is made of wear-resistant, fire-resistant and waterproof PVC tarpaulin, the second layer is made of aluminum film pearl cotton for thermal insulation, and the third layer is Oxford canvas for sealing. Therefore, our aviation duct is more durable than other rigid air ducts, and can last for 4-5 years under normal use. In the long run, our air duct is more useful and practical.
