AxiTwin100 Counter-Rotating Fans

Particularly in IT, telecommunications, network technology, and industrial applications, highly integrated electronics require cooling that safely reaches all of the components. In some cases, conventional single-stage fans are too weak, but the installation space doesn’t allow for multiple fans.

With AxiTwin 100, two individual fans connected with an innovative flange work together by rotating in opposite/counter-rotating directions. This enables the downstream fan to convert residual swirl from the upstream fan into airflow which increases efficiency compared to individual fan solutions. As a result, AxiTwin delivers maximum performance with minimum space requirements.
