The 3218JH4 from EBM-Papst is a compact and powerful DC axial fan with a flanged ring, measuring 92×92×38 mm. The fan delivers an impressive free air flow of 285 m³/h and a maximum static pressure of 800 Pa – all in a small form factor. It is ideal for demanding applications where high flow and compact dimensions are crucial.
Thanks to S-Force technology and a wide voltage range of 20–58 V DC, it is perfect for industrial electronics, cooling units, and server rooms where reliable cooling is critical.
