The RG125-19/14NM from EBM-Papst is a compact DC centrifugal fan with backward-curved blades, designed for applications where efficient airflow and low power consumption are crucial. The fan measures 180 × 180 × 40 mm and delivers up to 60 m³/h at free air flow. With a wide voltage range of 12–28 V DC, it is suitable for battery-powered and embedded systems.
Thanks to its flat and rectangular housing, the RG125-19/14NM is well-suited for applications in medical equipment, control cabinets, and electronics cooling where installation space is limited. Optional mounting positions provide great flexibility during integration.
