Centrifugal fans are mainly used in various fields of the national economy such as metallurgy, petrochemicals, electric power, urban rail transit, textiles, and shipping, as well as ventilation in various places. With the intensification of competition in the fan manufacturing industry, mergers and acquisitions and capital utilization among large fan manufacturing enterprises are becoming more frequent. Domestic excellent fan manufacturing companies are increasingly focusing on market research, especially in-depth studies of the industrial development environment and product buyers. Let's understand the difference between axial fans andCentrifugal fanwhat it is!

　　General ventilation fans (usually medium and small centrifugal fans and axial fans) are widely used, but what are the differences between common centrifugal fans and axial fans?

　　The difference between axial fans andCentrifugal fan1. Different exhaust directions. The exhaust direction of axial fans is straight along the axis, with the air intake and exhaust ports on a parallel line. The exhaust direction of centrifugal fans is perpendicular to the air intake direction, allowing for 360-degree directional exhaust.

　　2. Different installation difficulties: Axial fans are relatively easy to install, usually mounted directly on walls or connected to ducts. The installation of centrifugal fans is quite complex.

　　3. Difference in air volume and air pressure: Axial fans have relatively small air volume and pressure, with almost no air pressure, while centrifugal fans have larger air volume and pressure. When there are many duct elbows, and the suction and delivery distances are long, and the duct resistance is high, centrifugal fans must be used.

　　4. Different appearance shapes: Axial fans are generally cylindrical, while centrifugal fans have a snail-like appearance.

　　5. Different motor connection methods. The motor of axial fans is generally connected inside the fan body, while the motor of centrifugal fans is connected by a shaft, usually externally connected to the suction cylinder of the fan.

　　Main uses of axial fans and centrifugal fans: Axial fans and centrifugal fans are two different products among fan types, and their main function is to ventilate air in the environment.

　　1. The use of axial fans is very extensive, with airflow in the same direction as the blade axis, such as electric fans and air conditioning outdoor unit fans operating in an axial manner. They are called "axial flow" because the gas flows parallel to the fan axis. Axial fans are usually used in situations where high flow rates and low pressure are required. Axial fans are fixed in position and move air. Axial fans are mainly composed of fan impellers and housings, with a simple structure but very high data requirements.

　　2. Centrifugal fans rely on input mechanical energy to increase gas pressure and transport gas mechanically, functioning as dynamic fluid machinery. Centrifugal fans are widely used for ventilation, dust removal, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings; for ventilation in boilers and industrial kilns; for cooling and ventilation in air conditioning equipment and household appliances; for grain drying and selection, wind tunnel air sources, and air filling and propulsion for hovercrafts.

　　With the development of science and technology, people's requirements forCentrifugal fanuse are also increasing. From the current development trend of centrifugal fan technology abroad, the capacity of centrifugal fans is developing towards larger size, higher efficiency, high-speed miniaturization, and lower noise. The capacity of large centrifugal fans continues to increase. With the large-scale development of various industrial installations, the required capacity of various centrifugal fans is also increasing, and the market for large centrifugal fans will grow in the coming years.
