GX-CS3-I ???

Air in the line water line sounds like some kind of a bad seal

[avator]

It's basically a water jacket around the cylinder. Not really any way for the compressed air to get to it. And if it did, at pressures over 3k would be more than just air bubbles. It would be a spraying mist. Seems to me it's more like cavitation somewhere. It's possible I didn't get the jist of the description.

[Mr.P]

It is definitely air in the water line -blows bubbles if i put the end of the return hose below the surface.  If water is getting in there is no sign of it anywhere including in the gun.  Maybe whatever gap the air is coming out of his so small that it really only lets air out?  I switch the water pump off as soon as it cools down a bit so it’s not to have water running through it without air on the other side pushing back.

The amount of air mixed in does not seem to change when the  pressure increases but that seems unlikely. i havent checked very carefully. 

But forget about that thing - its days are numbered I’m sure.

Just bit the bullet and ordered a new GX-CS4 from the factory website. Got free shipping and used a 10% off coupon. Total cost $504 to my door
I can hardly wait. What coolant do you fellows suggest? I've read somewhere about using Zerex G48 anti-freeze and other places say use distilled water mixed with "water wetter". Curious to know what you fellows suggest.

Thx

 I would go with an eco friendly automotive antifreeze if there is any chance the compressor is exposed to freezing temps. Otherwise I have been using a water boiler anti corrosion additive in mine, gives better heat transfer and protects the various metals from reacting.

I used the premixed Walmart brand Dexcool.  I have yet to have it get much over normal body temp when filling my guns, even those that take a 5000 psi fill or holds 580cc of air!

When you get it, I would fill the water reservoir with distilled water and turn on the power.  This will start the water pump and flush the lines.  Then drain and repeat until you get all the garbage out of the lines and the water is running free and clear.  The drain it, start it one more time (just briefly) to clear the rest of the water from the lines. Dump that water and fill with the coolant.  Turn it on one more time and let the water pump run a minute of so to get all the air our t of the lines, then top off with coolant if needed.  Now, turn it one, set your auto-stop to 5000 psi, install the dead-head plug, open the air release valve and start the compressor.  Close the air release and watch how quickly and quietly it fills to 5000 psi!  Once it stops, rewear the air pressure from the air release valve and you're ready to rock n roll!  Enjoy!

Great advice. Can you tell me what the little tiny hose hanging out the bottom on one side is for?

That is the condensent drain, it's attached to the internal water separator.  Any water resulting from condensation during operation will be blown out that drain when you open the pressure release valve after a fill.

So that's the valve everybody keeps talking about "burping" open every 10 minutes or so during a fill to purge any moisture from the system to keep it out of your bottle or gun?

Yes!! I do every 5 but that’s me

Doesn't it take the air pressure down a good bit? I mean the pump is trying to fill the tank or gun and you take away some of the built up pressure. How much does this add to the fill time?

It does but that’s ok it’ll re fill back up . The only time you’re filling long is when filling big tanks and also remember the run time is 20 minutes run 30 minutes cool and when you’re done filling keep the cooling fan running a few minutes

 The quick open close of the bleeder barely looses any air pressure, as it vents from a small moisture reservoir.

water boiler anti corrosion additive

Mr. James, would you care to shed a little light on just exactly what this stuff is sir?

Thanks
