Galvanized steel duct: the most used one on the market, the earliest historical ventilation duct, made of galvanized sheet steel, suitable for the transportation of general air with low humidity, no heat preservation and noise reduction function, production and installation cycle long. Inorganic glass fiber reinforced plastic duct: a relatively new type of duct, which is made of glass fiber reinforced inorganic materials, is fire-resistant, corrosion-resistant, heavy, hard but fragile, and will be easily deformed and broken by its own weight. It has no heat preservation and noise reduction function. , The production and installation cycle is very long. Composite glass fiber board air duct: the type of air duct in recent years, using centrifugal glass fiber board as the base material, inner covered with glass cloth, outer covered with moisture-proof aluminum foil cloth (imported sheet is coated with thermal black acrylic polymer inside, and the outer layer is thin-grained Cloth/aluminum foil/kraft paper), after being compounded and dried with fireproof adhesive, it is made by cutting, grooving, bonding reinforcement and other processes. Appropriate reinforcement measures are adopted according to the section size of the duct and the size of the wind pressure. Fiber fabric air duct: It is also often called cloth bag air duct, cloth air duct, fiber cloth air duct, fiber fabric air duct, cloth air duct, fiber fabric air distributor, etc. It is the latest type of air duct at present. This kind of flexible air distribution system woven by special fibers is a kind of air delivery terminal system that replaces traditional air supply pipes, air valves, diffusers, heat insulation materials, etc. It is an air delivery terminal system that can uniformly deliver air mainly by fiber penetration and a unique air outlet mode of nozzle jets. It has a flat air outlet, large air volume, no blowing feeling; the overall air supply is evenly distributed; anti-condensation; easy to clean and maintain, healthy and environmentally friendly; beautiful and high-grade, diverse colors, outstanding individuality; light weight, negligible roof load; system Quiet operation, improving environmental quality; simple installation, shortening the engineering cycle; flexible installation and reusable; comprehensive system cost saving, high cost performance and other advantages. The air distribution system has a history of 35 years. The quality has been recognized by customers in all walks of life. In China, the fiber fabric air duct system is still in its infancy, but in other countries, it has been used extensively for more than 30 years to achieve energy conservation and environmental protection. In the next development, we hope that China itself can slowly and fully use fiber fabric air ducts in this regard, and raise air-conditioning pollution, ventilation and energy saving, emission reduction and environmental protection to a new level. The fabric air duct produced by Shanghai Environmental Technology Co., Ltd. will allow you to achieve the best results in terms of air conditioning, ventilation, pollution, energy saving and environmental protection.
