The 6318HU from EBM-Papst is a compact and powerful DC axial fan from the S-Force series, specifically designed for demanding environments. With an airflow of 545 m³/h and a robust die-cast aluminum housing, it delivers reliable performance where it really matters. The fan operates on 48 V DC and is fully encapsulated according to IP68 — electronics and windings are completely potted for maximum protection against water and dust.
Thanks to its IP68 rating and UL approval, the 6318HU is well-suited for industrial and outdoor applications with high demands for sealing, for example in marine technology, process cooling, or harsh automation environments.
