FOCUS ON EC FAN ONLY
The PC50B12300A (Φ50×300mm) DC Cross-flow Fan – also known as a tangential fan – is specifically engineered to meet the uniform airflow requirements of narrow, elongated spaces such as those found in microwave ovens. As a reliable 12v cross flow fan and high-efficiency dc cross flow fan, it features a 12V rated voltage, a rotational speed of 2400 RPM, and a stable airflow output of 180 m³/h.
Operating noise levels are as low as 43 dB(A) – comparable to the quiet atmosphere of a library – and significantly lower than traditional AC fan solutions delivering equivalent airflow. This makes it particularly well-suited for home environments where strict acoustic performance standards are required. Beyond household appliances, this model also serves as an excellent cross flow fan for HVAC systems, offering versatile integration possibilities.
The product offers dual-mode, stepless speed control inputs (0-10V DC / PWM), allowing system integrators to dynamically adjust fan speed based on real-time thermal loads or ambient temperatures. This ensures that energy consumption is precisely matched to actual demand—rather than operating continuously at full capacity—thereby achieving significant energy savings across the entire range of operating conditions.
