APC ACF503 Roof Fan Tray 120V 440 CFM for NetShelter SX | Rack Fans

When rack density rises, enclosure cooling has to be specific—not approximate. The APC ACF503 roof fan tray is built for NetShelter SX 750 mm wide by 1,070 mm deep enclosures and delivers up to 440 CFM of airflow, helping move warm air out of the cabinet where it accumulates. This is the kind of cooling accessory that earns its place in a serious infrastructure build. The roof-mounted design preserves rack layout while improving thermal management at the point where heat naturally collects. For teams managing servers, switching, or storage in enclosed spaces, that means more consistent operating conditions without adding complexity to the floor plan. The 120 VAC, 50/60 Hz electrical profile makes it straightforward to deploy in common North American environments. At 2.4 inches high and 22.58 pounds, it is sized for the enclosure platform it serves rather than adapted after the fact. That fit matters: better alignment with the cabinet means fewer compromises during installation and a cleaner path to stable airflow under load.
