Description
The NMB 4710PS-20T-B30-B00 is a reliable 200VAC AC axial cooling fan manufactured by NMB Technologies Corporation (MinebeaMitsumi). This model is part of the NMB 11925PB series and is designed for industrial cooling applications requiring stable airflow, compact installation dimensions, and long-term operational reliability.
According to the NMB product specification, 4710PS-20T-B30-B00 is the legacy part number corresponding to the updated model designation 11925PB-B0L-EA-00. Both model references describe the same 119mm class AC axial fan product family and may appear in different procurement documents, equipment records, and replacement references.
The fan features a compact 119 x 119 x 25.5 mm frame size with a shaded pole induction motor, aluminum housing, black plastic impeller, and ball bearing system. It provides reliable forced airflow for electronic equipment, industrial control systems, power supplies, and ventilation applications.
