The order of filters on this portable lunch box filter arrangement?

[rons]

I bought this used years ago and tried it out. It hissed at me and I though it was a air gasket leak, or something worse.
So I shelved it until a month ago. Turns out the long dryer (horizontal) has a air vent and it is working as designed.
The original idea was to use it as a small station for some air brushes. It's nice to shot Imron type paint for touch-ups
and not have to get all suited up. Just take a deep breath, a few triggers presses, walk away until fumes are gone.
Hardly no clean up. I put a link here for Chicago Air Brush.

So the question about the box. I did a lot of reading about the order of filters.
I learned it as 1. Coalesce, 2. Particle, 3. Dryer.

The box is 2, 1, 3. There is a clear plastic window on the box cover. It looked nice before I started the paint prep work for a light tan color.
The window lines up with the red/green bulb on top of the coalesce unit. Changing the order messes up with this window placement.

Is it supposed to be 1,2,3?

I added all the non-black stuff on the outside. It must be a thing used in a research lab or a medical instrument. ???
I went to the aluminum recycle place this morning and I hope I didn't make a mistake by keeping this.

I assume your goal is to have clean and dry air.
I see the regulator is installed last. This is not
optimal at all. Then the regulator drops the
pressure, really what it is doing is restricting down
the flow through the needle and seat, and then
shutting off all together when demand stops.
That being said, the pressure drop and velocity
increase of the air from the needle and seat
will make the air drop its moisture. Best to
catch this free precipitation of moisture afterword
and take advantage of this.
So put a coarse filter first, as not to fowl the
regulator. Then the regulator, then the water
trap, then the fine filter. This is the most
efficient way. But you need to do what works
for your emotional state of being. I am just
telling you the physics of what is happening
with the equipment you have.
The old standby setup of
Filter-Regulator-Lubricator
is flawed. It should be
Regulator-Filter(which is most often also water trap)-Lubricator.

When I look at manifold units made by Devilbiss the regulator is usually last.
Except for the breathable air unit at the end.

Its 2,1,3

And on an airbrush or a detail gun they have a regulator at the actual tool, or on a air brush just before it goes to the tiny 1/4" air brush hose.

I run a iwata HP-C and a RG-3

I use a homemade one.
Coalescing->Desiccant->Motor Guard->Reg.
It's my understanding that you meed a filter after the desiccant to catch the dust from the beads.



@Doozer You make a good point about the regulators position in the stack.

Yeah I use one of these on my airbrush rig. filter and regulator either at the gun, or on airbrush before the mini hose.

My stuff is lined up like yours for a desiccant canister.

In this case there is no desiccant. The long filter spills air constantly out a side vent.

What about the Thermonics box? What was it used for? I bought it for under $50 in my hunt-for-surplus days.
