AC Fans are electromechanical devices that consistently use an alternating current (AC) to provide cooling airflow. AC fans tend to be smaller and quieter than their DC counterparts, making them ideal for applications such as office and home appliances. The W4E315-CS20-70 is a specific model of AC fan from Ebmpapst, offering a wide range of features and functionalities.

Features of the W4E315-CS20-70

The W4E315-CS20-70 has a number of features, which include:

• Speed range of 1,100 to 4,000 rpm
• Airflow from 20 to 60 m3/h
• Maximum static pressure of 0.45 mmH2O
• PTC thermistor
• Integrated EMC filter
• Noise reduction of up to 6 dB(A)
• Minimal vibration and noise level

Application Field

The W4E315-CS20-70 is especially suited to application areas where size and noise are critical factors, such as offices, small electrical appliances, refrigeration and air conditioning units, and medical or laboratory equipment. The fan is designed to provide reliable and quiet operation within the specified operating parameters.

Working Principle

AC fans work by converting electrical energy into mechanical energy. This is done by an electromagnetic coil which is made up of windings of insulated wire. The electric current produces a magnetic field which interacts with a permanent magnet, causing the fan’s blades to rotate. This rotation creates a pressure difference between the inlet and outlet of the fan, which in turn creates an airflow.

The speed of the fan is determined by the frequency of the AC voltage applied to the electromagnetic coil. Using the PTC thermistor found in the W4E315-CS20-70, the speed can be regulated, ensuring that the fan runs at an optimal speed while still maintaining a minimal noise level.

Conclusion

The W4E315-CS20-70 is a reliable and quiet AC fan from Ebmpapst. It is ideal for applications in areas where size and noise are important considerations. With its wide range of features and functionalities, this fan is sure to provide a reliable and efficient cooling solution for any project.
