EC fan is an electronic frequency-controlled fan, whose working principle is to control the motor speed through a frequency converter so as to adjust the air volume and air pressure. EC fan has a high control accuracy and can achieve precise air volume adjustment, which is suitable for applications that require precise control of air volume and air pressure, such as air conditioning, ventilation systems, industrial equipment, etc. EC fan has relatively low power consumption and high efficiency, and also has low noise and low vibration and other characteristics.
