OEM 220V Double Inlet Didw Fans Centrifugal Radial Fan Blower Outer Rotor

Product Specification

Product Applications

The DKT external rotor fan is widely used in various air conditioning units, air curtains, and heating/cooling fans, and also plays a significant role in ventilation systems for industrial enterprises and residential buildings. The double-inlet centrifugal fan mainly consists of key components such as the impeller, volute, and motor.

The impeller features forward-curved blades and is constructed with a wheel cover and central plate, all riveted together. Each component is manufactured using stamping molds, ensuring precise dimensions, reliable profiles, and excellent aerodynamic performance. The impeller undergoes dynamic and static balancing corrections to ensure smooth operation and low noise.

The volute is coated using specialized equipment, making it both durable and aesthetically pleasing. The motor is of the external rotor type, housed within the volute and directly coupled with the impeller. This design is compact, providing smooth rotation and low noise.

External Rotor Ball Bearing Pure Copper Motor - I5 Grade

This external rotor ball bearing pure copper motor features outstanding performance characteristics, making it ideal for demanding industrial and commercial applications. The external rotor design ensures a compact motor structure, enhancing direct and efficient power output. The motor utilizes high-quality ball bearings to maintain smooth operation at high speeds, reducing friction and noise, which extends the motor's lifespan.

The use of pure copper materials provides excellent electrical conductivity and heat dissipation, ensuring efficient energy conversion and effective cooling during operation. This not only enhances the motor's operational stability but also reduces energy consumption. The I5 grade indicates superior protection, effectively resisting dust and liquid ingress, and making it suitable for various challenging environments, including high temperatures and high humidity conditions.

Additionally, the motor design incorporates safety and reliability features to prevent overheating and other potential issues, ensuring robust performance. Whether used in industrial production lines, commercial facilities, or other high-demand settings, this motor delivers powerful support and ensures continuous, stable operation of equipment.

DKT External Rotor Fan Square Shape Features

The DKT external rotor fan's square shape design offers several notable advantages. Firstly, the square shape provides flexibility in installation and layout, making efficient use of space, especially in tight or irregular areas. This design enhances the fan's stability, reducing noise and imbalance caused by vibrations, and ensuring smoother operation. Additionally, the square housing is made from high-strength materials, offering durability and impact resistance to protect internal components from external environmental factors. Furthermore, the square shape contributes to a clean and aesthetically pleasing appearance, allowing the fan to blend seamlessly with various architectural and decorative styles, enhancing the overall visual effect.

Centrifugal Metal Fan Wheel

Automation technology ensures precision and consistency in the manufacturing of multi-wing centrifugal metal fans, enhancing overall product quality and performance. High-strength metal materials are processed using advanced cutting and forming techniques, resulting in superior durability and resistance to centrifugal forces. The multi-wing design optimizes airflow efficiency, enabling the fan to deliver a larger air volume within the same dimensions. Balanced through dynamic testing, the fan operates smoothly with low noise and minimal vibration, ensuring efficient and stable performance. The metal surface is treated with coating processes that provide excellent corrosion and abrasion resistance, making it suitable for various environmental conditions. The real-time quality monitoring systems on automated production lines ensure the reliability and performance stability of the fan across different working environments.
