How Much Do You Know About Spiral Duct?

Definition and characteristics of Spiral Duct

Spiral duct is a kind of ventilation and exhaust system component with high production precision, easy installation, small wind resistance and good air tightness. Its characteristics are as follows:

1. Excellent strength and durability: The spiral duct material is usually lightweight aluminum or galvanized iron plate, which is not easy to deform, can be used in both hot and cold environments, and has a long life.

2. Low wind resistance: The air flow in the hvac spiral duct is very smooth, the inner wall is smooth, and dust is not easily accumulated, so the wind resistance is small and the ventilation and exhaust efficiency will not be reduced.
