Airflow Management Kit

The APC AR7708 NetShelter SX Air Recirculation Prevention Kit is a server accessory designed for data centre operators who need to maintain thermal efficiency inside 42U and 48U enclosures. It addresses the problem of warm exhaust air looping back into the cold aisle through gaps at the vertical mounting flanges.

Sustained Thermal Behaviour

By sealing the gaps between the vertical mounting flanges and the side panels, the kit stops warm exhaust air from re-entering the equipment intake area during continuous operation. This maintains a consistent temperature differential across the servers, reducing the risk of thermal throttling or premature component wear under sustained load.

Build and Mounting Implications

The kit weighs 0.25 KG and uses black components sized to match the enclosure frame with a maximum height of 2134.00 mm, width of 19.00 mm and depth of 19.00 mm. Its lightweight construction adds negligible mass to the rack while the precise dimensions ensure a flush fit that does not interfere with side panel removal or routine hardware maintenance.

Questions about this item

Does the AR7708 kit add noticeable heat or power draw when installed in a 42U enclosure running continuously?

The kit is a passive airflow-management accessory with no moving parts or electrical connections, so it adds no heat or power draw in a 42U enclosure.

What existing NetShelter SX enclosure hardware is required for the AR7708 kit to function?

The kit closes gaps between the vertical mounting flanges and side panels, so it requires a NetShelter SX enclosure that has those flanges and panels in place.

Will the AR7708 kit fit older NetShelter SX cabinets that are only 42U tall?

Yes, the kit includes components sized for both 42U and 48U enclosure heights, so it works with the older 42U cabinets.
