APC AR7751W Vertical Exhaust Duct Kit for SX Enclosure | Rack Accessory

Capture hot exhaust air at the enclosure level and return it to room cooling systems with APC’s Vertical Exhaust Duct kit for NetShelter SX. Built for 600 mm wide short-range enclosures, this rack-mountable accessory mounts to the top rear of the cabinet to manage exhaust before it mixes with the room. That matters in high-density environments where uncontrolled hot air can raise inlet temperatures, reduce cooling efficiency, and force the facility to work harder than it should. By directing exhaust air into a controlled path, the duct kit supports more predictable thermal behavior across adjacent racks and helps preserve the performance margin infrastructure teams depend on. The kit includes baying hardware, duct panels, foam gasket strips, mounting hardware, a rear door and bottom sealing kit, and roof components for installation. With a 2-year limited warranty and RoHS compliance, it is a practical choice for teams that want a purpose-built airflow accessory rather than a field-made workaround. For deployments where thermal control affects uptime, this kit earns its place.
