DiaForce Diagonal Compact Fans

DiaForce is ebm-papst's most innovative diagonal compact fan that combines the high airflow volume of an axial fan with the high back pressure capabilities of a centrifugal fan. The result is the performance of a counter-rotating fan with less noise and a significant power reduction.

In today's digitally connected world, users store and manage enormous amounts of data. Keeping that data safe and accessible means ensuring the infrastructure needed to support it stays at an optimized temperature. Whether in servers, autonomous technologies, artificial intelligence, or IoT solutions related to 5G, DiaForce delivers the powerful cooling needed with minimal energy consumption and noise, key considerations in this growing industry.

Counter-rotating fans, or two axial fans in series rotating in opposite directions, are often used in these applications. They are known for their high static pressure and ability to cool densely packed electronics in the chassis. The electronic components restrict airflow, so high pressure is needed to ensure uniform cooling throughout the enclosure. The tradeoffs are the energy consumption needed to power the fan coupled with noise. ebm-papst developed an air mover that delivers the necessary static pressure but with quieter and much more efficient operation .
