Duct Centrifugal Fan

The duct centrifugal fan is a device specially used for pipeline ventilation systems. It combines the wind pressure advantage of centrifugal fans and the characteristics of pipeline installation structure, and is suitable for air delivery and exhaust needs in medium and high resistance environments. The product is widely used in commercial buildings, underground garages, kitchen smoke exhaust systems and industrial ventilation projects.

In terms of structural design, this type of fan usually adopts a centrifugal impeller and volute structure, so that the air is thrown outward from the center under the action of the impeller, thus obtaining high wind pressure, which can effectively overcome the pipeline resistance. The air inlet and outlet are mostly standard pipeline interface forms, which are convenient for direct connection with the ventilation pipeline, and the installation and maintenance are relatively convenient.

The casing is generally made of galvanized steel plate or sprayed steel, with good strength and durability. Some models can also be built-in with sound-absorbing materials or configured with shock absorption devices to reduce operating noise, suitable for places with high environmental requirements.

In practical applications, the duct centrifugal fan can be used in air supply, exhaust or air circulation systems, especially suitable for working conditions with long pipelines or large system resistance. Its stable wind pressure output capacity makes it an important equipment in the pipeline ventilation system. The duct centrifugal fan is an essential part of modern pipeline ventilation projects.
