Centrifugal fans have many advantages, but there are also some disadvantages. The following are the disadvantages of several common centrifugal fans:

(1) Noise: Centrifugal fans will produce higher noise levels at high speed. This is caused by the friction and compression between the impeller and the air when rotating.

(2) Size: Centrifugal fans are usually larger than axial fans with the same air volume. This is because the centrifugal fan needs to have a rotating impeller and a long inlet and outlet air duct. Therefore, in applications where space is limited, size limitations may need to be considered.

(3) Pressure characteristics: the wind pressure characteristics of the centrifugal fan are relatively gentle at the working point, and when the working point deviates from the design point, the change of wind pressure and air volume may be larger. This can be a challenge in some applications where precise wind pressure control is required.

(4) Energy efficiency: The energy efficiency of centrifugal fans is usually low. Due to the large volume and process design limitations, the aerodynamic efficiency of centrifugal fans is lower than that of axial flow fans. Therefore, in applications with high energy efficiency requirements, it may be necessary to consider other types of fans or take energy efficiency improvement measures.

 

Despite these drawbacks, centrifugal fans are still one of the most commonly used fan types in many industrial and commercial applications, as centrifugal fans typically have a higher air volume, higher pressure, higher reliability, and a wide range of adaptability.

Guangdong Chungfo Electronic Technology Company is a wholesale DC centrifugal fan manufacturer, there are 12v centrifugal fans, 24v centrifugal fans, like 6015 this type of centrifugal fan is also often used in air purifiers. In addition, some quiet centrifugal fans and plastic centrifugal fans will be produced, and the quiet centrifugal fans are especially suitable for medical atomizers because of their low noise, which provides a guarantee for users who need a quiet environment. We have many years of experience in the production of centrifugal fans, excellent quality, first-class service, welcome major buyers to come to purchase consultation.

Want a breath of fresh air? Choose a centrifugal fan with an air purifier! It's a winning combination, and let's see why.

First of all, the centrifugal fan can produce a high static pressure capacity during the rotation process, our centrifugal fan usually includes a rotating impeller and a spiral guide housing. This design can collect air in the center and spray it at a higher speed under the action of centrifugal force, resulting in a larger static pressure. This means that it can effectively capture and remove harmful substances such as particles, formaldehyde, and odors in the air to ensure the purity of indoor air.

Secondly, the application of centrifugal fans in air purifiers is also reflected in its silent performance. Some special designs of the blades of centrifugal fans will reduce the production of noise, just like our centrifugal fans usually use smooth blade curves to reduce the production of noise when the air flows. In some specific cases, we will also reduce the noise level of the centrifugal fan by increasing the number of blades, more blades can make the noise more easily isolated and dissipated. Noise is reduced, thus improving the user experience of the air purifier.

Our 12v centrifugal fan is a combination of the above two points, in addition to this fan, there are other fans you can choose, such as plastic centrifugal fans, brushless centrifugal fans, we are also a good choice for wholesale air centrifugal fans.

Overlapping design refers to optimizing the space layout of the fan blades or multiple fan modules to overlap the air flow paths of multiple fans to improve the air flow or heat dissipation effect. This design is suitable for equipment that requires efficient heat dissipation, especially in the case of limited space can significantly improve cooling efficiency.

Chungfo Electronics focuses on manufacturing a variety of efficient cooling fans, although our fans do not currently use overlapping blade design, but we use advanced materials and technologies, such as metal cross flow fan, bldc exhaust fan, plastic centrifugal fan, to ensure that the product in a long time to maintain efficient and stable heat dissipation capacity. Our 110V and 220V cooling fans perform well in industrial, domestic and electronic devices.
