FOCUS ON EC FAN ONLY
The PA4028B24H 40x40x28mm EC-DC compact axial fan is a high pressure axial fan for medical imaging equipment and other high‑performance, compact applications. It is specifically designed for medical and healthcare devices, including axial fan for ventilator and oxygen concentrator, sterilizer cooling, and laboratory cooling equipment. This compact 4028 axial fan for communication base station also serves industrial, communications, consumer electronics, and HVAC fields.
Operating on a 24V DC rated voltage, it features a high‑efficiency brushless DC (BLDC) motor drive. With its balanced airflow‑pressure characteristic curve and compact, standardized dimensions, it seamlessly replaces the industry‑standard 4028 mounting hole pattern. This makes it an ideal high performance axial fan for industrial frequency converter, server rack cooling, and power module thermal management.
PBM offers customized axial fan solutions covering multiple dimensions—from motor type to connector options. Whether you are developing industrial frequency converters, communication base station equipment, medical testing instruments, home appliances, or HVAC ventilation systems, the PBM technical team provides full engineering support—from sample confirmation and performance verification to mass production delivery.
