3. The length is different, the length of the canvas soft joint is mostly 150-250mm according to the standard atlas; the length of the flexible duct is generally about 0.5-2.5m.
4. Different materials, canvas soft connection quota is used; the flexible duct is made of metal, plastic-coated chemical fiber fabric, polyester, polyethylene, polyvinyl chloride film, aluminum foil and other materials.
5. The flexibility is different, the flexibility of canvas soft connection is general; the flexibility of the flexible duct is high.
Canvas soft joints are mainly connected with air ducts and air conditioners and fans to reduce noise, vibration, expansion, etc. The flexible duct material is connected to the louver tuyere, square diffuser, etc. Due to the suspended ceiling, the air outlet of the air duct cannot be directly connected to the air outlet. Add flexible hoses for flexibility.
