Aosun | Centrifugal Exhaust Fan Supplier in China
Centrifugal exhaust fans are designed to move gases or air. They convert rotational energy into airflow using centrifugal force. Unlike axial fans, centrifugal exhaust fans push air at right angles to the fan’s intake. So, they can make higher static pressure. That’s why they are ideal for systems that need stable airflow through long ducts, filters, or high-resistance environments. Because of their capability, centrifugal exhaust fans are widely used in hotels, industrial ventilation, metallurgy, dust collection, chemical processing, food production, commercial HVAC systems, and high-temperature exhaust applications where durability and performance are very important.

What is the Centrifugal Exhaust Fan？
A centrifugal exhaust fan is an excellent industrial ventilation equipment. It converts mechanical force into centrifugal force to promote air flow for high-performance exhaust, thermoregulation, and dehumidification. Choosing the right centrifugal exhaust fan reduces energy costs and maintains operational continuity and safety. You can use it in manufacturing plants, warehouses, and more.
Components of Centrifugal Exhaust Fans
- Impeller: The impeller is the main component of a centrifugal exhaust fan and determines the efficiency and performance of the exhaust air. It rotates at high speed and generates centrifugal force during operation.
- Housing: The centrifugal exhaust fan housing protects the internal components. It has excellent mechanical strength and protects the internal components from damage. The housing is also designed to reduce noise and vibration during operation, resulting in quieter and smoother operation.
- Drive Mechanism: Aosun offers centrifugal exhaust fans with different drive modes to suit your many applications. Centrifugal exhaust fans typically use an electric motor to power the impeller, ensuring proper and efficient operation.
- Inlet/Outlet Ducts: Centrifugal exhaust fans have ducts that provide air inlets and outlets while directing a rapid flow of air for efficient air circulation.
How do Centrifugal Exhaust Fans work？
Centrifugal exhaust fans use an electric motor to drive an impeller that rotates at high speed. As air enters the fan through the inlet, the rotating impeller generates centrifugal force. Centrifugal draws in air and pushes it out quickly so that it flows into the outlet duct and out. Centrifugal exhaust fans have different blade shapes for different performance and airflow directions, so you can choose the right one for your application.
Types of Centrifugal Exhaust Fan
Forward-Curved Fans
The forward curved fan blades are angled in the direction of impeller rotation, giving it a larger exit angle. It can exclude a larger volume of airflow. Although it has lower pressure and a slower speed, it runs smoothly and more energy efficiently. It’s perfect if you’re looking for an exhaust fan with a high air circulation capacity for small space projects. Plus, it is much quieter, allowing you to use it in noise-sensitive scenarios.
Backward-Curved Fans
The backward curved fan has a smaller exit angle with the blades exiting in the opposite direction of the impeller rotation. This allows it to generate more pressure at the same rotational speed, making it ideal for exhausting air in high-resistance environments. A backward curved fan for high static pressure also has greater energy efficiency and longer run times, and you can achieve rapid heat dissipation. In addition, the design makes it more resistant to contamination and damage, giving it a longer service life.
Radial Fans
The blades of the radial fan do not bend, and the exit angle is kept at 90 degrees to draw air in parallel. This makes it better able to handle air rich in impurities such as smoke and dust. It can help you efficiently improve air quality in harsh environments. And its blade design makes it easy to inspect and repair
