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 2002 air plenum kit has one horizontal and two vertical air plenums. The air that flows from the front
top 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.
The following figure shows the air flow inside the air plenum.
