FOCUS ON EC FAN ONLY
This 200mm DC forward curved centrifugal fan is made especially to cool tiny data centers and communication cabinets that run on 48V DC. With a static pressure of 120 Pa, an airflow of 400 m³/h, and a power consumption of just 52.8 W, it runs on 48V DC power. With a diameter of 200 mm, the forward-curved impeller design provides sufficient airflow that efficiently penetrates spaces between equipment and dust filters inside the cabinet, ensuring consistent cooling for key components such as servers and base station BBUs. A typical 19-inch cabinet's ventilation resistance can be overcome by the 120 Pa static pressure, and three to five rack units' cooling requirements may be satisfied by the 400 m³/h airflow. Because of its IP44 protection and noise level of less than 65 dB (A), the cabinet fan may be used indoors. It may be changed as needed using an environmental monitoring system and supports 0–10V/PWM speed modification. Its 52.8W low power usage drastically lowers running electricity expenses. It is the perfect cooling option for edge computing nodes and 5G aggregation cabinets because of its extended lifespan of 50,000 hours and stall prevention, which guarantee dependable functioning in unattended situations.
