FOCUS ON EC FAN ONLY
The PC43B24420A (Φ43×420mm) DC Cross flow Fan – also known as a tangential fan – is specifically engineered for use in confined, elongated spaces such as those found in precision electronic equipment, optical instruments requiring thermal management, laser cooling systems, and medical imaging devices. As a High Airflow Crossflow fan, it features a rated voltage of 24V DC, a rotational speed of 2600 RPM, and delivers a uniform airflow output of 202 m³/h – making it a true High Airflow Crossflow fan in its class.
This cross flow cooling fan’s ultra-slim 43mm diameter design allows it to be effortlessly integrated into the narrow air ducts of precision devices—including optical instruments, medical imaging equipment, and laser marking machines. By providing uniform heat dissipation and airflow coverage along the entire length of the impeller, it ensures that critical components – such as optical engines, laser generators, and mainboards—operate consistently within a stable temperature range.
PBM is more than just a fan manufacturer; we are your dedicated solution provider for precision thermal management systems. Whether you are developing a cooling system for optical instruments, a thermal module for laser equipment, a medical imaging device, or a temperature control system for telecommunications cabinets, PBM’s technical sales team is ready to provide comprehensive engineering support—from initial sample validation through to mass production delivery.
