FOCUS ON EC FAN ONLY
The PC43B24420A (Φ43×420mm) dc cross flow fan is specifically engineered for cooling applications within the narrow, elongated spaces typical of precision electronic equipment. As a high-performance brushless cross flow fan, it features a rated voltage of 24V, a rotational speed of 2600 RPM, and a uniform airflow output of 202 m³/h.
In electronic cooling scenarios, this crossflow fan functions as an ideal cross flow fan for electronics cooling, ensuring comprehensive, uniform heat dissipation and airflow coverage – free of dead zones – across the entire length of the impeller, effectively cooling PCBs, optical engines, and heating components. Operating at a low noise level of just 40 dB(A) – significantly lower than traditional AC fan solutions with equivalent airflow capacity – it is particularly well-suited for office environments with strict acoustic performance requirements.
PBM offers customization options to satisfy certain OEM assembly needs and ensures that our tangential fan conforms with worldwide safety regulations, including as CE, UL, and RoHS. From initial sample validation to final mass production delivery, PBM's technical sales team offers thorough engineering assistance.
