The following are some ventilation duct types suitable for plant ventilation and cooling projects:

- Galvanized steel pipe:

- With high strength and durability, it can withstand large air pressure and airflow impact in the plant.

- Good fire performance, in line with the safety requirements of the plant.

- The price is relatively affordable and the cost is low.

- Fiberglass air duct:

- Excellent corrosion resistance, suitable for environments where corrosive gases or chemicals may be present in the plant.

- Light weight for easy installation and maintenance.

- Good thermal insulation performance, helping to reduce energy loss.

- Phenolic composite duct:

- Low thermal conductivity, excellent thermal insulation performance, can effectively reduce the energy loss in the ventilation process.

- Has a certain noise reduction performance, can reduce the noise of the ventilation system.

- Lightweight material, easy to install.

- Stainless steel air duct:

- Very good corrosion resistance, suitable for all kinds of harsh plant environment.

- Smooth surface, not easy to accumulate dust, easy to clean and maintain.

- High strength, long service life.
