Centrifugal 400Hz fan

400 Hz Centrifugal Fans

ETRI 400Hz centrifugal fans are designed for applications requiring high static pressure in a compact form factor. When pressure losses are significant or installation space is limited, they provide a highly effective alternative to axial fans.

Their ability to generate high static pressure at moderate airflow rates makes 400Hz centrifugal fans ideally suited for cooling electronic equipment, onboard systems, and industrial applications where air must circulate through confined spaces, filters, or heat exchangers.
