Air Plenum
Air plenum orients the air flow in the front-to-back direction inside the equipment to be compliant with GR-63
issue 4 requirement.
NCS 2006 air plenum kit has two horizontal and two vertical air plenums. The air that flows from the front
top inlet and the front bottom inlet are channelized to the right vertical plenum, inside the equipment, and
then to the exhaust air channel towards the left vertical air plenum. The air flow is deflected by 90 degrees
and exited out in the rear end.
