Add targeted ventilation to SmartRack cabinets with the Eaton SRFAN3U fan panel. Built as a 3U rack-mounted accessory, it uses three 4-inch fans to move air through enclosed rack spaces that can trap heat around servers, switches, and storage gear. For teams managing dense infrastructure, that extra airflow helps reduce thermal buildup and supports more predictable equipment performance. The SRFAN3U is designed for practical deployment: it includes a 6-ft. cord and mounting hardware, and it runs on 120 V AC. Its panel-mount format keeps the installation clean while preserving the rack layout. That matters in environments where every unit of space is planned and every thermal margin counts. This model is a strong fit when passive ventilation is not enough and a full cooling system would be excessive. It gives procurement teams a focused, cabinet-level cooling accessory from Eaton with the durability expectations and warranty coverage that enterprise racks demand. For SmartRack owners, it is a straightforward way to improve airflow without redesigning the enclosure.
