DC Fans: ASFN12371 application field and working principle

DC FANs have found many applications in industrial, medical, military and commercial electronic systems. In addition to cooling and re-circulating air, DC FANs have become popular for components such as resistors, capacitors, diodes, transistors, amplifiers and other electronic components.The ASFN12371 has been specifically designed as a DC fan for ventilation and air circulation purposes. It utilizes a robust centrifugal blower with an integrated electrical motor to create a steady stream of airflow through its radial vent design. This fan is especially well suited for systems that require a high amount of airflow while operating in harsh conditions and is also often used in aircraft cabins, HVAC systems and cooling applications.The ASFN12371 works by using the power of an electric motor in order to turn the fan blades. This causes a stream of air to be created and directed towards its outlets. The speed of the motor determines the airflow created, and as such, is adjustable. The fan can generate a maximum air velocity of 5.0 m/s which can generate an air velocity of up to 0.5 m/s at each of the four outlets.In addition to its air circulation capabilities, the ASFN12371 also provides noise reduction capabilities. Utilizing the latest in acoustic technology, the fan has been designed to produce a low noise level. The fan has also been designed to minimize vibration to further control any residual noise.The ASFN12371 is also designed to be highly efficient. It has an energy efficiency ratio of 86%, a power factor of 0.94 and a power consumption of 12.7W at its maximum operating speed. Additionally, this fan has a low starting current and is designed to be current limited in order to protect its environment and to ensure that the fan is working efficiently at all times. The ASFN12371 is UL approved and comes with a 2 year limited warranty. It is also designed to be a global product and has been tested for American, European, Asian and Middle Eastern markets. The fan can also be temperature compensated so that it can work efficiently in any region, climate or environment.The ASFN12371 is an ideal DC FAN for applications that require a steady stream of air circulation, while being energy efficient and providing low noise levels. This fan is well suited for use in areas such as data centers, server rooms, computer rooms, and other electronic equipment. It is highly reliable and is designed to provide long-term operational performance.
