Double Plenum

[ChaChaMan]

I came up with this arrangement for mechanical components of an Air Handler (Please see attachment)
Plenum Fan + N-Coil +Discharge Plenum.

Following everyone's suggestions,

1.I placed the N-Coil after the Fan Motor so as to remove the risk of a damp Fan-Plenum environment.
2.I use a Discharge Plenum so as to do away with transitions such as elbows, pant fittings, offsets, etc.

Concern : I seem to be pressurizing 2 Plenum chambers, the Fan Plenum and the Discharge Plenum. Is this a problem ?

Any other comments on the present configuration ?

Thx in advance !

Hi ChaCha,

Looks a lot like what's installed at my house. No problems here. Just don't build it leaky ;-).

Good on ya,
