How to distinguish between ventilation duct equipment and smoke exhaust ducts

How do you differentiate between ventilation ductwork and smoke exhaust ducting? What are their characteristics? How should we prepare? Duct system design, duct transportation and maintenance precautions, and the purpose of ductwork are discussed. Ductwork primarily functions for ventilation, smoke exhaust, and transportation. However, there are some differences between ventilation ducting and smoke exhaust ducting. Duct production line manufacturers will explain these in detail.

Ventilation ducting and smoke exhaust ducting are both types of pipes, but their primary difference lies in their use. Smoke exhaust ducts are specifically used for smoke exhaust, while ventilation ducting primarily supplies air and exhausts smoke, typically serving one or more rooms or equipment. The differences between the two are also reflected in their respective characteristics. After installation, the ductwork surface should be smooth and free of impurities. Outdoor ductwork should be protected from snow and rain. When crossing settlement joints, the ductwork must be sleeved as designed, and the gap between the duct and sleeve must be sealed with filler.
