Factory spiral ducts

Spiral ducts are a type of air duct used in air conditioning systems in factories and other industrial settings.
They are made of metal tape coil and are round, with no welding, air leakage, or water leakage.
Here are some characteristics and benefits of spiral ducts:
Efficient airflow:

Spiral ducts have a round shape that equalizes internal pressure, allowing for more efficient airflow through a building. This results in better air movement and less air leakage, which can cause reduced energy efficiency in HVAC systems and poor air quality in buildings.


Spiral duct installation often costs up to 50% less than the installation of a rectangular duct. This includes the installation of the parts, warehousing, transportation, waste disposal, packaging, and the product itself.

Aesthetically pleasing:

Spiral ducts are more aesthetically pleasing than rectangular ducts. They have a curved shape that implies softness and seamless flow, unlike the hard edges of rectangular ducts. Spiral ducts are often used in places where the duct systems remain exposed, such as in modern industrial and corporate workspaces.

Less noise:

The gentle curvature of spiral ducts causes less turbulence than rectangular ducts with sharp corners. This creates a quieter atmosphere in offices, schools, hospitals, and other commercial buildings.

Easy to maintain:

Spiral ducts are easier to maintain than rectangular ducts. They are often self-sealing, and their airtight duct joints make air leakage an afterthought. They are also less likely to accumulate dirt and dust on both external and internal surfaces, reducing the chance of becoming a breeding ground for bacterial growth.

Spiral ducts have a wide range of applications, including air return ducts of purification systems, central air conditioning, ventilation pipes, and exhaust pipes of trains and subways, and transporting loose particles in factories.

They can be customized to fit the unique needs of each structure, and they can be affixed with thermal insulation material for better thermal control and energy efficiency.
