ebm-papst AxiTwin 100 Counter-Rotating DC Fan

ebm-papst AxiTwin 100 Counter-Rotating DC Fan delivers high airflow with minimum space requirements. This fan consists of two individual fans connected with an innovative flange that works together by rotating in opposite/counter-rotating directions. This enables the downstream fan to convert residual swirl from the upstream fan into the airflow, which increases efficiency compared to individual fan solutions. The AxiTwin 100 counter-rotating fan operates from a 3.3V to 20V supply voltage range and 1KHz to 10KHz PWM frequency range. Typical applications include medical, industrial, renewable energy, server cooling, mass storage cooling, cabinet cooling, radio base station cooling, and 5G/IoT.
