APC ACF137 Rack Air Removal Unit for 750 mm Wide Frames | Cooling

Maintain stable operating temperatures in high-density rack deployments with the APC Rack Air Removal Unit SX for 750 mm wide frames. Designed for rack environments where hot exhaust can recirculate and raise inlet temperatures, this accessory helps direct warm air away from active equipment and supports more consistent cooling performance. In enterprise racks, thermal margins are often the difference between stable service and avoidable throttling. This unit is intended for APC rack systems that need controlled air removal rather than improvised airflow management. By helping separate exhaust from intake paths, it supports cleaner thermal design in enclosures carrying network, compute, or storage gear. For infrastructure teams, the value is straightforward: fewer hot spots, less strain on room cooling, and better protection for equipment operating near capacity. It is a practical fit for environments where rack density is increasing and thermal discipline matters as much as power and cable management.
