The only difference is the structure. Direct drive centrifugal fans have a motor structure that is directly attached to the impeller shaft. As a result, direct centrifugal fans have blades that rotate at strong speeds, creating strong suction. (In contrast, the indirect centrifugal fan has a motor structure that is indirectly attached to the impeller shaft, driven through a belt)
Direct drive centrifugal fan
Advantages – disadvantages of direct centrifugal fans
👉 Advantages:
– Suction speed is strong, fast, and continuous
– The fan works more efficiently thanks to a direct drive to the blades.
👉 Defect:
Do not use in an acidic environment, high-temperature environment, or chemical environment… Because the gas flow in extreme conditions can overheat the engine or corrode the engine. This causes the fan to fail quickly and reduces its lifespan.
Application of direct drive centrifugal fan
Use for industries
Thanks to strong suction, centrifugal fans are directly used for dust extraction, exhaust gas for cement plants, mining, brick kilns, steel fabrication furnace and kilns…
Used to supply fresh air to the pits…
Installation for systems with long and complex pipelines
With fast wind speed, and strong suction, capable of pushing air away, creating great pressure. In projects with complex piping systems, this fan helps to transmit the wind far away.
Where there is fine dust, the dust of a small size
Many industrial parks and factories generate small fine dust. Centrifugal fan with strong suction, can suck up dust in the environment. Centrifugal fans can be installed directly for dust collection and filtration systems. As a result, the factory space is clean, and dust-free, and ensures a safe environment for workers’ health.
Ventilate the basement, pressurize the emergency stairs
Direct drive centrifugal exhaust fans can be used for basement ventilation. Ensure the supply of clean air in the basements of high-rise buildings. Thus, limit harmful gases, and dust.
Use a fan to pressurize the exit stairs when a fire occurs. Prevent smoke and fire from spreading into the stairwell area. Protect people from fire, and have time to get out of the fire area.
Thus, direct drive centrifugal fans have high applications for many different environments and areas.
