AC Centrifugal fans are designed to produce directional airflow needed for drying and cooling in HVAC, electronics cooling, and industrial processes. These fans feature a drum-shaped design that produces high pressure of air required for application. Sofasco International stands out as an AC centrifugal fans manufacturer because our fans are designed to meet the airflow requirements of various applications. Our team of engineers and technicians possess extensive knowledge and experience in fan design and engineering. We offer various customization options, including fan sizes, blade types, materials, and performance specifications.

How do AC Centrifugal Fans Work?
AC centrifugal fans are distinguished by their impeller design, which offers them better resistance and makes them suitable for applications, such as dust collection, drying, blowing away excess coatings or debris, fume exhaust systems, and so on. These fans work on the principle of centrifugal force and employ air pressure differentials to produce airflow. Here is an overview of how centrifugal AC fans work.
- The AC centrifugal fan comprises a blower wheel or an impeller and a series of blades that are arranged in a radial or spiral pattern. When the fan receives power, the impellers rotate in the fan housing.
- Air is drawn to the fan through the inlet and flows in a straight line towards the fan’s center.
- The centrifugal force is produced when AC centrifugal fan blades force the air outward from the center of the fan.
- This airflow pattern causes the air to move outward in a radial way and then diffuses when it hits the fan housing. This diffusion causes increased air pressure that forces the air to flow in a different direction.
- The pressurized air is discharged from the fan’s discharge port or outlet port to perform desired tasks.
Key Beneficial Features of Our AC Centrifugal Fans
Over the years, Sofasco International has established itself as a leading AC centrifugal fans manufacturer. The following features our fans have contributed to their popularity.
- Our AC centrifugal fans are designed for maximum efficiency in different motor configurations, single inlet and double inlet, and different blade designs. We can provide the fans in the following blade designs.
- Forward-Curved Blades: These fans feature shallow blades facing the direction of the rotation. The blades are suited for applications where a large volume of air needs to be generated at low speeds.
- Backward-Curved Blades: As the name suggests, these blades are positioned away from the rotational direction. They are larger than forward-curved blades.
- Radial Blades: These blades are fitted on the impeller and discharge the accelerated air radially. We can provide AC centrifugal fans fitted with radial blades in motor-driven or belt-driven designs.
- Backward Inclined Aerofoil Blades: The aerofoil blades are equipped in fans where elevated or ambient temperatures are required, such as in power generation, chemical, resource recovery industries, and so on. Backward-inclined aerofoil blades assure quiet operations and high efficiency.
- Customized AC centrifugal fans help move air with minimal energy consumption, reducing carbon footprint and energy costs.
- These fans are made from durable material that helps ensure their lasting performance in challenging environments. For instance, the impeller of our AC centrifugal fans are made from an aluminum plate that makes them lightweight, durable, and reliable. This durable construction and other design features makes them ideal for operating environments ranging from: -25°C to 60°C.
- These fans are equipped with ball bearings with an expected operating life of 50,000 hours at 40 degrees Celsius.
- Our AC centrifugal fans meet the ROHS and CE standards.
How to Choose the Right AC Centrifugal Fan?
Here are some selection criteria for AC centrifugal fans.
- Determine the use: As said before, an AC centrifugal fan can serve many purposes. For instance, you may use it for cooling, ventilation, drying paints, and so on.
- Understand your application requirements: This would involve consideration of factors, such as static pressure (inches of water column or Pa), airflow volume (CFM or m³/h), and temperature range. In addition to this, consider additional factors, such as environmental factors, operating environments, restriction of noise level, sizing, and so on.
- Choose the right blade type for application: We can customize your AC centrifugal fans in different blade designs; however, the right selection would depend on your application. If you are already using an AC centrifugal fan in your facility, perhaps, you may have an idea about these blade types. If not, you can get in touch with our experts today to learn more about them.
- Evaluate the form and size: This consideration would depend on the application of the fan. You must measure the length and height of the available area and then decide upon the fan’s specifications.
- Focus on the construction of the fan: Do you plan to use the fan in environments where they may incur corrosive components, high temperatures or chemicals? If that sounds yes, you must communicate your special construction requirements to our team.
- See the performance curve: You must check the performance curve offered by the manufacturer. It would give you an idea of the power consumption, airflow, and pressure of the fan. Once, you see this, you will know if the fan is a suitable match for your application.
- Consider compliance and standards: If you are working in an industry that follows stringent safety measures and performance standards, then you must consider the appropriate compliance and standards. Remember, the compliance and standards imply the quality of fans.
