Here are plumbing and wiring for the 2001 coach.  Three different air system drawings in this year, minor changes.

I had two of the small compressors, the OEM had a filter on the end plate.

I have a bigger Thomas by itself on a easy to remove board where all of the stuff was before.

The rest of the stuff in on a panel on the back side wall of the bay.  Easy to service.  Connected as they are in a 2003.  I have a much bigger dryer to connect when we get home.

And an ARB backup/utility compressor, ceiling mounted on a panel bolted into steel.  Didn't quite finish all the connections before we left in Dec. Three way valve, either or both.  If it is not selected for air system it provides utility air (bike tires etc)  you can get 2 of the ARB compressors for the price of a big Thomas compressor.

Last two are 2003 variations.

Roger that is very similar to what I will end up with. I like the little Thomas for the bladder pressurization and the ARP for everything else. Using the 9700 wire will interface it with the ARP in the auto position. Still will have manual override when i want. 👍👍

Scott, I have the bigger compressor but yours might be the same as far as air intake. The base of where the compressor sits on is where the intake is.you can see the black hose going from the base up to the compressor. The bolt and nut in the middle of the base holds the cover for the filter.

None on mine. On top of head the unused port has a plug in it

Scott,

That is the dangest thing I have ever saw.

It does pump, but I don't know were the intake is . Suspecting bottom side of piston, yes I've never seen a compressor like this.

Take a look at this diagram Scott...looks like there may be a reed valve on the inside, so air intake is from the inside.

In looking at diagram it looks like these have a reed valve for intake and exhaust.  From this diagram I would say one side of head is intake and other exhaust.  The picture that Scott has of the pump has arrows pointing out on both sides so that is the reason for the plug on the unused side.  Now as for where air is coming from on the pump Scott has must have a reed valve on the top of the piston.  In the picture there is something on the side of the crankcase. Could that be the air intake?

They have a side air intake, one of mine had an additional air filter attached to the end plate.

Air come in from the side of the crankcase. See page top middle picture of page 3.  Shows the intake coming from crankcase.

Thank you. I would of never imagined having a reed on top of the piston. So they show a plastic ratchet holding a filter on the side of the crankcase. I actually did notice that black plastic button but didn't dedicate enough time to look at it. I will tonight when I get done at work. Im sure it has the factory original filter. In the environment I live in I will at least install a new filter and actually think about a little K&N type filter retro fit, thinking a crankcase breather filter. Again Thank You 👍👍

Scott, test the pressure output of your small compressor, it should be 100+ psi.  I got a rebuilt kit at ZORO for $94.  They are closer to $200 now.  After one, I decided to put the $ into a more capable compressor.

Your little compressor needs to get the HWH tank and the air to the bags to 90 psi or more before it will do any leveling.  It is slow.

Roger, did you do a write up when you upgraded your compressor? I'm probably dreaming it was an easy in n out.

Yep it not going to put out 60 psi. No air awning. Yep its slow, yep it will work slide bladder seal air. Yep the standby by twin ARB will operate vacuum to 22 inches, yep it will operate bags when needed, although currently they hold for weeks. So im going to run what I brung. I like the idea of the ARB and will upgrade soon. Adding a aux air normally closed solenoid to bypass check in. Line 57 should resolve vacuum issues, but I still want for all the others reasons. I have hi pressure 1/4 line and fittings to remote locate 1 liter desiccant filter and will fit and make next. Will also leave port for ARB when its in my hands..
So the bladder tank is isolated during leveling. Non issue

Upon closer review my filter was actually missing . I measured the outside of the flange and have ordered a filter that should clamp around the outside. Will stick out a bit but I dont think it will be a issue as high in the compartment that it is.. will probably leave the center plastic anchor removed.

So put on were I originally wanted too. Not secure enough installation  Pulled and plugged inlet and welded tube to end plate. Cut hole and reinstalled I'm happy with this and will add to my annual maintenance program to clean.

Separated aux air manifold on compressor to add 1 liter desiccant dryer and a additional pressure gauge to monitor compressor pressure. Separation is just past compressor check valve so everything after stays at pressure. Water separator and filter dumps pressure and moisture still every cycle as normal. So with system at 100 psi with compressor commanded off I have four minutes to open or close slide with tank capacity. Will still hold 20 inches of vacuum at 80 psi but falling past  that point. Normal slide movement is complete at one minute duration or less. Air lines are a bit overkill but I have on hand and I know they will never fail being 3000PSI capable . New desiccant on order already.

Scott, the air to deflate or inflate the bladder comes from the HWH tank which gets its air from the small compressor. I have my compressor on while deflating the bladder (HWH tank pressure drops) , extending or retracting the slide, and then while inflating the bladder. The compressor shuts off when the HWH tank and the pressure switch gets to about 105 psi (depending on the pressure switch adjustment).

Yes but I wanted to know consumptions and working times. Also vacuum versus pressure so as to set minimum operational pressure. 105 sound perfect for cut out but minimum on my system to function normally is 80 psi in regards to needed vacuum. 20 psi for pressurizing bladder.
