  • Flexible insulated air duct and modular flexible insulated air-duct system
    Patent number: 11662118
    Abstract: Provided are a flexible insulated air duct and a modular flexible insulated air-duct system; the flexible insulated air duct includes an air-duct main body (1); the air-duct main body (1) includes an inner air-duct layer (5) and a heat-insulating layer (4) integrally formed on the inner air-duct layer (5); the inner air-duct layer (5) is arranged inside the heat-insulating layer (4), and the heat-insulating layer (4) is a rubber/plastic material. The modular flexible insulated air-duct system made by assembling a main air duct (7), a branched air duct (8), and a connecting air duct (9) may be rapidly connected on-site using a zip fastener to form an air-duct system having any configuration.
    Type: Grant
