FOCUS ON EC FAN ONLY
The PC50B24198B (Φ50×198mm) DC crossflow fan– is designed for use in confined spaces such as those used for cooling precision electronic equipment and communication devices. As a high-efficiency cross flow fan and an ideal cross flow fan for electronics cooling, it provides a 16V rated voltage, 2400 RPM speed, and a uniform airflow output of 150 m³/h. Its compact 50mm diameter design allows for easy integration into the narrow airflow channels of devices such as microwave ovens and projectors, achieving uniform heat dissipation along the entire length of the impeller for precision components such as PCB boards, control boards, magnetrons, and optical engines, preventing performance degradation and malfunctions caused by localized overheating. While primarily optimized for electronics cooling, this cross flow fan for HVAC systems can also be adapted for broader airflow management applications where narrow, elongated spaces are required.
Equipped with high-efficiency brushless DC motor (BLDC) drive technology, it saves twice the energy compared to traditional AC fan solutions. PBM can be customized to OEM assembly requirements. We offer not only fan components, but also comprehensive precision cooling solutions throughout the entire R&D process.
