APC AR7754X417 Vertical Exhaust Duct Kit | SX Enclosure

Control exhaust at the enclosure instead of letting hot air recirculate through the room. The APC AR7754X417 vertical exhaust duct kit is designed for 800 mm wide tall-range SX enclosures, giving infrastructure teams a more deliberate way to channel warm air away from the cabinet and into the intended exhaust path. That matters when thermal margins are tight. In high-density deployments, unmanaged exhaust can raise inlet temperatures, reduce cooling efficiency, and force the room to work harder than it should. A dedicated duct kit helps preserve airflow discipline at the rack level, which supports more predictable thermal behavior and cleaner separation between supply air and exhaust air. For teams standardizing APC enclosure deployments, this accessory fits the operational model: specific, controlled, and built for the enclosure family it serves. It is the kind of component that helps protect uptime by reducing thermal ambiguity in the rack row. When the enclosure is part of a larger cooling strategy, the exhaust path should be just as intentional as the equipment inside it.
