much more than A/C equipment. 400 microns is very good for a/c....
Now imagine maybe 1000 times that....
baking to near the melting point of the glass to remove more than moisture,
but to remove other chemical contaminants.
A simple way of looking at it, is that the more molecules of "air" removed, the less obstructions there are in the path of electrons to flow to the screen, any obstructions reduce screen brightness..... In addition to this, contaminants eventually "poison" the cathode, and reduce it's ability to release electrons to shoot at the screen....
Not quite the same requirements for a good a/c system to work, even though they are both vaccum'd, but to achieve slightly different results.
