The inner wall of the fiber Fabric Air Duct is smooth, and its air resistance is lower than that of the metal Air Duct. The operating load of the fan is smaller, which can reduce energy consumption and meet the cost reduction and efficiency improvement goals of the workshop. Fabric air ducts maintain a stable air velocity through overall air supply, which can prevent condensation and ensure production safety. The surface of the Bag Air Duct is made of dense and seamless fiber material, without the seams or dead corners of metal air ducts. It is not easy to accumulate dust, is convenient to clean, and avoids dust pollution of the production environment. Fiber fabric air duct, with their advantages of energy conservation and consumption reduction, precise temperature control, cleanliness and anti-fouling, have reduced the long-term operating costs of new energy workshops, ensured the stability of the production process and product yield, and helped enterprises achieve the production goals of high efficiency, safety and sustainability.
