This is a picture that shows what is under the fancy oval and vinyl covered pieces.

The black duct to left is the cool air duct. The fan blows directly down into this air channel. The opening at the front allows the air to blow out onto the top of the oval (towards the front of the coach). If I want more air in the galley, I can drill holes in the edge of the channel and allow some air to escape. Initially, I want as much air as I can to blow to the front of the coach.

The white piece is the return filter assembly. The Newell techs made this by cutting the original plastic grill in half. They installed some sort of control board inside of the ductwork. The channel around the white part is the return air channel and has the gap that you see as well as another further back into the galley.

What is not obvious is that Newell went to a lot of trouble to insulate everything. There is a self-adhesive pink insulation on the ceiling and some of the black foam self insulating material on the channel. Again, probably overkill for this application, but more is well....better.

The wires are for the low voltage lights that were installed into the trim pieces.
