Industry Demand

• Air supply and ventilation: In environments like factory workshops where harmful gases are produced and must be exhausted, external fresh air needs to be supplied indoors. This requires air transfer ducts with large flow and low pressure, for which spiral ducts are most suitable. Typically, galvanized steel duct pipes are used, while stainless steel duct pipes are used in corrosive or extremely humid locations.
• Cold air supply: The most common application is for central air conditioning ductwork, which requires insulation. Spiral ducts can be lined internally with insulation material while maintaining an aesthetically pleasing exterior.

We offer spiral duct machines suitable for manufacturing spiral ducts, whether you need them for general ventilation or cold air supply applications.
