FOCUS ON EC FAN ONLY
This 108mm EC forward curved centrifugal fan is made especially for automated hand dryers with high speeds. It has an airflow of 256 m³/h, an air pressure of 261 Pa, a power consumption of just 48 W, and a noise level as low as 64 dB(A) thanks to a 230 V EC motor. The necessity for quick hand drying is effectively met by the forward-curved impeller design, which produces tremendous airflow in a small package. Depending on the use scenario, the EC motor may balance performance and noise because it is around 30% more energy-efficient than conventional AC options and provides 0-10V/PWM stepless speed adjustment. This thing is really quiet, so it is perfect for bathrooms in malls, airports, and other places where they have strict rules about noise. The low noise levels of this thing make it a great choice for these kinds of places. Stall prevention and a 50,000-hour lifetime provide dependable performance at high frequencies. Embedding in an incredibly thin body is made possible by a specially engineered volute housing, which produces a strong and uniform airflow. Additionally, these curved fans work well with tiny ventilation systems, medical equipment, and air purifiers.
