Aux Compressor Replacement Options

Q: Why does anyone need to re-level while Parked?
A:I hear that in California sometimes the ground moves.
-
With a 20 year old coach, that took a purposeful 3 year approach to zero everything out, I’m still looking for leak free. Until then I level with blocks for long stays in one place (football season) or set it down on the stops if the site is actually level, or add air periodically during short stays.
The aux compressor is better starting the big noise maker, but, I ha be to watch the condensate produced.

Good one, Dan. We did have a nice ride while parked at MCCC in Indio a couple of years back. I don’t remember whether we had to re-level.
Eric, please post an update with the results of your compressor install.

Hi Bryan,
Still collecting my thoughts on which compressor to go with. Spent several more hours this morning locating
and correcting two tiny leaks, because …….. even tiny leaks add up over time.More to follow.

Put a Gast in and fix all the leaks that’s the best bet , hope that helps

Greetings PC Brothers and Sisters,
Getting ready to install my new Aux
Compressor. After many discussions with
tech reps, and comparing specs, I decided to go with the GAST compressor. It was more expensive than other compressors,
but I think a better value. Time will
tell.
One question before I install. I want to clean up some of the old airline,
and there is a component I don’t recognize.
No markings of any kind. From the
compressor, the air goes through a (failed) check valve and then through this mystery
component, then to the steering bay.
What is this component?
Thanks again for all the help and advice,
-
Any arrows or markings on it?
While it looks a little large, my first reaction is it could be a check valve. I cannot think of any other device in the location you describe.
-
Good Morning Jon,
No markings. Air is
able to exit the line, so if it is a check valve, it is bad. My first inclination is to remove it – just another
potential future leak. Filter? -
Assuming there is only air going in and out, with no other connections it is probably a check valve.
A filter or water trap would have a means of draining or servicing.
The check valve downstream from the aux compressor needs to be far enough away so the check valve is not affected by the heat of compressed air so that might explain its location. If there was another check valve it is possible someone was unaware there already was one.
-
After looking at your picture the rectangular piece tied down with blue ties is a check valve. I’ve seen these installed in older applications. Not used often anymore due to collecting water thus spring inside weakens.
-
Al brought up a good point. Observation if that is in effect it would be brass on brass and therefore to work correct would have to be installed vertically. Prob has a internal spring that has to be overcome by small pressure to open. Were notorious for getting small particles under seat. Just a thought– Bob
-
Your first line off the compressor should be a loop or coil of sorts of copper tubing. It will help cool the air and help to minimise moisture.
Call Liberty and ask Troy about it.

Thank you all very much.

Gast compressor works great – quiet and powerful. Eliminated several defective devices during the install, including this ‘mystery’
item. After cleaning it up, found it to
be a very heavy and defective $60 rusted check valve.

Evidently I left the breaker panel switch on the other day and came to the bus this morning with a compressor that was pulling serious AC amps and was very hot (I think it had tripped the panel breaker and when switched back on showed the high amps). I removed it for inspection, let it cool and it has decided to start working again, but I take the warning for what it is…
I have a handy dandy California Air Tools 1HP on the shelf, I have had good luck with these in BBs, but in order to fit this in the hole behind the Cruisairs and under the batteries I’d have to re-imagine the stand the Gast sits on as the CAT is too tall relative to the Gast.
Any other ideas short of a $700 Gast? My dream goal would be to air up the entire coach on 110VAC as I have done with some BBs but that probably entails some re-circuiting. Open to ideas….
