AC fans provide a reliable cooling solution for processes that involve heat generation, such as electric motors, computers, and heavy-duty processing equipment. AC fans are generally classified into centrifugal, backward-curved, axial, and cross-flow fans. The 109S405UL AC fan from NMB Technologies Corporation is an axial fan that works on a friction-slip clutch motor and operates with a wide range of AC motors using an electronic speed control. This fan boasts an ultra-low noise-level and long life cycle due to its construction from synthetic resin and die-cast aluminum housings.

109S405UL Application Field

The 109S405UL AC fan is designed to provide reliable cooling for a variety of commercial and industrial applications. Its ultra-low noise-level is of great benefit when cooling items such as medical devices, computer equipment, and audio/visual devices like TVs and stereos. Due to its efficient construction, it is a popular fan for cooling machinery in factories and warehouses where noise levels must be kept low. It is also a great choice for helping cool data centers and server rooms.

109S405UL Working Principle

The 109S405UL fan uses a friction-slip clutch motor to turn its built-up blades. This motor consists of two parts: a stator and armature. The armature is fixed on a disc that is attached to the fan’s shaft, and the stator revolves at a set speed. As the armature revolves, it produces a friction force against the stator due to the static electricity generated and directed by the coils, creating a slipping force. This force helps turn the armature, which turns the fan’s shaft and generates the airflow.

The 109S405UL fan runs on a wide range of AC motors. It can be used in all types of motors, including induction, synchronous, and permanent magnet AC motors, as well as SCR-controlled universal motors. The speed of the fan can be adjusted using electronic speed controls to match with different electrical characteristics and enabling flexible and efficient operation.

Conclusion

The 109S405UL AC fan from NMB Technologies Corporation is an excellent choice for a reliable cooling system in commercial and industrial settings. Its durable construction from synthetic resin and die-cast aluminum housings ensures a long life cycle, and its ultra-low noise-level makes it a good fit for environments where noise levels must be controlled. Furthermore, its capability to operate with a wide range of AC motor types and adjustable speed make it flexible and efficient, creating a powerful cooling solution for all applications.
