The 255/2H from EBM-Papst is a compact DC axial fan with a flange, measuring 25 × 25 × 8 mm and designed for applications where space is limited but reliable airflow is crucial. The fan operates on 5 V DC and delivers up to 4.6 m³/h of free air flow with a maximum static pressure of 47 Pa.
Thanks to its small size and optional mounting position, the 255/2H is ideal for electronic equipment, embedded systems, and compact control cabinets where efficient cooling is required without taking up space.
