Made by winding glass fiber cloth and elastic steel wire, and wrapped with insulation material on the outer layer. Mainly used for gas transportation, especially suitable for flexible connections in irregular spaces. When the air duct is subjected to external pressure or vibration, it can ensure the maximum ventilation space inside the duct.

Equipped with elliptical, polygonal, and circular mufflers or rectangular tubes, all of which are made of perforated aluminum strips. Soft hoses are used inside and outside the muffler tube to better block the diffusion of sound sources from the air and noise from machines and air conditioning equipment. The sound insulation layer is 10mm to 50mm thick, and can also be customized according to different sound insulation requirements.
