CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory, duct sections can be made of galvanized steel, aluminum, stainless steel, or flexible composite (fabric/foil). The choice depends on the application, environmental conditions, and required durability.
The nominal size (diameter or width×height) ranges from 100 to 2000 mm, per ISO 7806. Custom sizes may be available from manufacturers, but you should confirm with the supplier.
Sheet thickness typically ranges from 0.5 to 1.5 mm, per EN 1505. Thicker sheets are used for larger ducts or higher pressure applications. The specific thickness should be selected based on the operating pressure and structural requirements, and verified with the manufacturer.
The operating pressure range is 500 to 2000 Pa, per EN 1507. The pressure class should be matched to the system's requirements, and you should verify the actual pressure rating with the manufacturer for your specific model.
