FOCUS ON EC FAN ONLY
The PC50B12290B (Φ50×290mm) dc cross flow fan – also known as a tangential fan – is specifically engineered to meet the uniform airflow requirements of applications involving narrow, elongated spaces such as air curtains. As a high-efficiency brushless cross flow fan and 12v cross flow fan, it offers a rated voltage of 12V DC, a rotational speed of 2400 RPM, and a stable airflow output of 260 m³/h.
This tangential fan functions as an ideal cross flow fan for air curtain systems. Its compact 50mm diameter allows for easy integration, enabling air curtain systems to create a complete air barrier effectively positioned above doorways. Compared to traditional AC fan solutions, our brushless DC crossflow fans deliver significant energy savings while meeting equivalent airflow demands.
We provide not merely fan components but comprehensive ventilation and thermal management solutions that span the entire R&D lifecycle. We also offer customization services to meet specific OEM assembly requirements. For further details, please contact our sales team.
