Working principle and advantages of centrifugal fans
The core component of centrifugal fan is the impeller, which is usually composed of multiple blades. When the motor drives the impeller to rotate, the blades push the gas to flow in the tangential direction, generating centrifugal force. The gas is thrown to the edge of the impeller under the action of centrifugal force and discharged outward along the flow channel of the volute. This process not only increases the speed of the gas, but also increases the pressure of the gas, enabling it to overcome the pipeline resistance and achieve long-distance transportation.

The advantage of centrifugal fan lies in its high efficiency and large flow gas processing capacity. Compared with axial flow fans, centrifugal fans can provide higher pressure at lower wind speeds, which is particularly suitable for application scenarios that require a large pressure increase. In addition, the structural design of centrifugal fan makes its noise level relatively low, which is particularly important for places that require a quiet environment.

Innovative design of Hongguan brand
As a company focusing on the research and development and manufacturing of fans, Hongguan has a variety of centrifugal fans in our product line. Our fans not only meet the needs of different industries in terms of performance, but also reflect innovation and practicality in design.

For example, Hongguan's 6-inch silent circular centrifugal duct fan, with its 2600RPM speed and unique appearance design, provides users with high-performance ventilation solutions. Our fans use external rotor motor technology, which not only improves efficiency but also reduces operating noise, making them very suitable for environments with strict noise requirements.

For another example, Hongguan's 12.5-inch circular centrifugal duct fan, with an air pressure of up to 738 Pa, can cope with more complex ventilation needs. The design of this fan takes into account flexibility and durability, ensuring long-term and stable working performance.

As a key component of the ventilation system, the performance of the centrifugal fan directly affects the efficiency and reliability of the entire system. The Hongguan brand provides the market with a variety of centrifugal fan options through continuous innovation and optimization of product design. Whether it is industrial production, commercial buildings or family residences, our centrifugal fans can provide suitable solutions to help users achieve efficient gas delivery and pressure increase. With the continuous advancement of technology, we have reason to believe that centrifugal fans will play a more important role in future applications.
