Product Applications

This product can be used in various air conditioning units, air curtains, and heating/cooling fans, as well as for ventilation and air exchange in industrial enterprises and residential buildings. The double-inlet centrifugal fan is carefully constructed from key components such as the impeller, volute, and motor. The impeller is made from forward-curved blades attached to the wheel cover and central plate through riveting. All parts are manufactured using stamping molds, ensuring precise dimensions and reliable aerodynamic performance. After dynamic and static balancing, the fan operates smoothly with minimal noise. The volute is covered using specialized equipment, making it both durable and aesthetically pleasing. The motor, designed with an external rotor, is cleverly integrated into the volute and directly connected to the impeller, resulting in a compact structure. This design ensures smooth operation and exceptionally low noise levels.

The external rotor ball bearing copper motor demonstrates outstanding performance advantages

With an IP54 waterproof rating, it effectively blocks dust and resists water splashes from any direction, ensuring stable operation in complex environments. The motor uses pure copper, which provides excellent electrical and thermal conductivity, ensuring efficient energy conversion and effective heat dissipation. The unique external rotor design makes the motor structure more compact and enhances power output. The use of ball bearings ensures high stability during high-speed operation while effectively reducing noise. Whether for large industrial equipment, various mechanical devices, or other applications, this motor stands out for its professional quality and reliable performance. Its superior waterproof, electrical and thermal conductivity, compact structure, and stable low-noise characteristics make it an ideal choice across various industries, providing powerful support for diverse applications.

High-Quality Multi-Wing Centrifugal Fan Wheel

It is composed of multiple high-quality metal blades, ensuring durability and long-term stable operation. The unique multi-wing structure significantly increases airflow and enhances air movement efficiency within the same dimensions. It operates smoothly and quietly, with minimal vibration and low noise, creating a comfortable environment. Precision dynamic balancing ensures no wobbling during high-speed rotation. Excellent surface treatment provides outstanding corrosion and abrasion resistance, suitable for complex working conditions. With superior aerodynamic performance, it achieves efficient energy conversion and reduces energy consumption. In ventilation and air conditioning systems, it is a critical component, delivering powerful performance and reliable quality to ensure the system's efficient operation.
