Title: GX-CS4 Compressor - A quick look!
Post by: Rat Sniper (AKA: PaulT58) on March 15, 2023, 03:52:34 PM
This was an impulse buy!  It was on sale with an additional percentage off for signing up for their newsletter.  Yes, I'm probably going to be inundated with even more spam e-mail, but I'm hoping it will be worth it in the long run!

First off, this is a beast of a compressor in a relatively small package!  Shipping weight was 34 lbs, so not too bad compared to others.  It does have a very sturdy carry handel and will run off a 12V supply.  The AC/DC converter is separate, but that's not to unusual.  The interesting thing with this compressor, it can be set-up in the upright position, or on it's side if you need a lower profile.

From their website:  The CS4 PCP compressor has a new upgraded 350W motor and a four-stage compression technology. It is very stable when working, and it is very quiet with only 70db. Maximum filling 5800Psi/400BAR. At the same time, it is equipped with a double-pointer pressure gauge, and the two-level setting auto-stop pressure, which is more secure.

This compressor is water cooled with a self contained water tank and a grease tank on the top of the compressor. The excellent cooling can achieve 5 hours of continuous work and can fill a maximum 6.8L gas cylinder.   It comes with all the o-ring, seals and springs needed for a complete rebuild. 

Here's a quick video overview of me testing it with a deadhead plug installed.  You can see it's really quiet [compared to most PCP Compressors] and does fill quite quickly. 

https://youtu.be/AvpIZNEB3Dk

The low RPM of the motor and the 4 Stage compression seem to keep thinks very cool also.  Being the anal individual I am, I had to add a thermometer just for peace of mind!  I also added an Hour Meter, but the low operating RPM of the compressor has hardly any vibration, so I'm not sure the Hour Meter will even work! 

Here are some picture of the temp after filling my Huben K1 from 250 BAR to 350 BAR.  Yep, it only got to 77.7F!  The manual says to leave the main switch on for about 1-2 minutes so the fan continues to run and the coolant continues to circulate.  I actually forgot to do this and shut in off right after filling the Huben.  The temp rose to a whopping 80F before it started to drop again!  This is the first time I have been able to fill the Huben to the max fill of 350 BAR because my Hill Compressor will only fill to 300 BAR. 

I have no idea how long it will last but with the heavy duty motor and low RPM operation, I feel it should be pretty durable.  Only time will tell for sure, but initial impression is pretty positive!

Heck of an impulse buy  ;D I’ve been eyeing the line up and the JTS one. How’d you hook up the thermometer and do you have a link to it? Did the hour meter register anything?

If you’re okay discussing it, how did you decide on this one and what others did you compare?

For me, the CS3-I with built in power supply is quite a draw. However, this one can go to a higher pressure and can fill tanks—I wonder if a CS4-I is in the pipeline. I’m also debating between the JTS and the CS3-I. Tough choices, but great to have!!

Paul,  you got a heck of a deal. When I looked on Amazon it was $700!
It looks good. I've been kinda looking for a unicorn compressor.

I say impulse, I have been looking for another portable that is more capable than the Benjamin Traveler I have, this one checked a lot of boxes!  Quiet, High Fill Capacity and relatively fast fill times were the Top 3 and this pretty much checks them all.

It was primarily the higher max fill rating.  Just about every airgun I own requires a 250 BAR fill or higher, having that extra ceiling knowing it can go to 400 BAR is needed was a huge plus!  I have 2 airguns that take more than a 250 BAR fill, so this will easily fill those as well.  Plus, they claim it will run for 5 hours filling a 6.8L tank!  I don't have a 6.8L tank, but if I ever decide to get one, I know I can fill it! 

The JTS and the CS3-I look to be the same compressor to me, both are 4500 psi max fill capacity and I believe both are 2 stage compressors.  The 4 stage compressor in the CS4 runs at a much lower RPM and produces less heat, which is what ultimately kills most compressors.  I'm sure the CS3-I is just as capable, but it really wasn't much more to get the CS4, so I figured, what the heck!  BTW, I just replied to your PM.

Standard warranty is 1 year like all the others. I purchased direct from GX and it was considerable cheaper than what Amazon is asking for it.

Also the Omega Trail Charger maxes at 4500PSI vs. 5800PSI.  Something must have changed in the design for the additional PSI capability?

Is the Omega a 4 stage compressor?  That seems to be the giggest change, that and the 350W motor.  The slow RPM also seems to be different than any other compressor I've seen.  When filling to 400 BAR with just the fill whip and deadhead, the amount of pressure it increases with each stroke is pretty amazing!

Needs a 24 volt to 12 volt 40 amp converter, and a few 20 volt 12ah Harbor Freight Hercules brand batteries to make it portable. A pair of those in parallel should run it for nearly an hour and not push the batteries hard at all (1.2C discharge rate). A single 12ah should be able to drive it and probably still be safe enough to not kill the batteries.

Today I took a few more picture of the CS4 and made a short video of a pressure test to 400 BAR/5800 PSI.

Lots of pictures below of the inside.  You can see the mall reservoir for the coolant, I used the Walmart brand of Dexcool with it PH neutral and safe for all cooling systems.  I also took a picture of where I mounted the probe for the temperature gauge.

https://youtu.be/FelxlMr1C6I

Here are some pictures of the grease pot and power supply:

The next pictures are of the inside of the compressor.  Here you can see the coolant resivior, 350X motor, radiator and the other components.  When bleeding the air after a fill there is very little moisture released, so it seems to do an excellent job of separating moisture from air, even at extremely high pressures.
Title: Re: GX-CS4 Compressor - A quick look!
Post by: Rat Sniper (AKA: PaulT58) on March 18, 2023, 06:35:25 PM
As previously mentioned, I used Walmart brand Dexcool 50/50 pre-mix.  It took about a liter to fill the cooling system.  I did fill it and flush it with distilled water first, then drained it and refilled with the Dexcool.  It the video of the pressuer test above, the starting temp was 71F and it only climbed 2 degrees which going from 0 to 5800 PSI!  It fillls fast even though it runs at a fairly low operating RPM, so heat is really not much of an issue!

These are selling on Amazon for $699.99 plus tax.  I purchased direct from GX Pumps, who offers free shipping also.  I ordered it on March 8th and it was delivered on March 14th, but that was also over a weekend.  The are currently selling for $659.99 on GX Pumps, but by using the Coupon Code GXPUMPS10OFF, it drops the price to $593.99, which is not bad for all this compressor has to offer! 

That Coupon Code should work on all the Compressors they offer and there is no need to sign up for a newsletter!  You can see all they have to offer on their website!

I do have mine spread out somewhat...
The Orcair 12v/110 compact will live in the truck along with a TBD truck gun. (possibly the Buccaneer in the Urban stock)
Big Red (AirMax MKII lives in Betty Lou's she shed.. it's role is tank filling.
The Vevor lives in the utility room in the house.
The Yong Heng is in the Red Shed and has taken over the role of gun filling. It sees more action than any other.
The Xisico GX-CS3, the newcomer to the collection will be the mobile unit. It will move to bench duty between the front porch deck and shooting deck at the bar/mancave.
As mentioned in another thread.. The Vevor and the Orcair will be become available for a couple package deals to a few locals that have shown interest.

Got to have back-up!  The Benjamin Recharge is the back-up to the Hill and the Benjamin Traveler is the back-up to the CS4 and also to mobile unit when needed!  The CS4 can also be mobile, but it's primary job now is to fill my Guppy tank, larger bottle guns and the guns I have that take a fill of over 250 BAR!  The Huben takes a 350 BAR fill and the, AEA Challenger and Ataman AP-16 Pistol take a 300 BAR fill, so those will get filled by the CS4!

when the cs4 gets here, it will be used for filling guns only so i dont wear out my F10 & shop compressor
 on tanks to fill my 300bar guns  uragan and piledriver.
all my other compressors are back-ups for each other.
last month when my cs3 failed, i was sick !!!  the auto shut off works very well same as with
the F10. once you can trust it, it will spoil you !!
i see the cs4 has a much nicer pressure gauge for set pressures........ 8)
i think i have a hand pump somewhere ?

 X2, I just prior to reading this, dug out the tire valve filler attachment that comes with the hand pumps, to pack along for emergency. Now I will add a bag of blast caps that I have not shot for some time now, I guess I could put a hand pump in the truck for filling blast cap bottles, safer than filling from a bottle ;)

 I would think it would be no issue, leave the atv running a spell after shutting the cooling fan off, I have run them off of the slightly larger garden tractor batteries following those steps. Make sure all lights etc. are off.

 PS we also have run sprayer pumps off atvs  for extended periods with out issue for hours at a time.

That's a good thought John... both are injected but, so are our trucks.
I run 18" LED light bars, winches, 500 watt bluetooth speakers and the weed sprayer sometimes without issue. I'm sure I would turn all that off before running a compressor.
I'm just wondering if a stater charging system would handle the wattage as does the alternator system in a vehicle. If I'm not mistaken, the CS3, for example, draws 250 watts.

its the in-rush at start-up and voltage spikes when shutting off the compressor that could harm the ECM
not the running of the compressor, but can the stator handle that load and maintain the correct output ?
keep in mind, your charging thru rectifiers (voltage regulator) of the ATV

Yep, that was my concern... it's all good, I have the 30 minute scba tanks for atv adventures. That is if I ever happen to need more than 3 or 4 mags for a run... I doubt it. I can always run back to the truck or campsite to refill. I also have that big gold filter I'm going to make a buddy bottle, of sorts, filler out of.

What if you were to run a deep cycle battery in parallel with the ATV’s battery and have a knife switch in-line to isolate it from the rest of the system while running the compressor?  It should charge while under way with the knife switch closed, then just open it to when you attach and use the compressor. That setup might still be more compact than a large tank strapped to the ATV.

This might be a safer solution then being stuck out in the woods

GX Pump E-L2 Portable 18V Cordless PCP Air Compressor,4500Psi/300Bar, Oil-Free, Powered by 1 x 7.8Ah Lithium-Ion Battery (Included)
I looked at those... I just know how often batteries go bad in my cordless hand tools and thought better of it.

Those are a really cool concept!  I just wonder how long those batteries last when running a compressor?  Seem they would draw a lot more current than your standard hand drill or weedeater!

I’ve watched some reviews on them it seems like they’re ok for a few fills but you can have spare batteries.

On a positive note....
I had a vision this morning.. it often happens while eating grilled pineapple pancakes and ham steak..
I have a small tupperware container on the bench next to the Yong Heng compressor. I keep the current in use probes in it during shooting sessions and then put them all away in the compartment case when finished for the day. I remembered one day a week or so ago, I bumped that bowl spilling some of the contents onto the workbench.
So I went to the Red Shed this morning, pulled the stool and the shop vac out from under the bench, grabbed a flashlight and went in.
Sure enough, there in the gravel right up against the wall was my missing SPA probe...  :o
That'll never happen again....
As some may know, that SPA probe is a small one piece probe. It attaches directly to the female foster without the need for a threaded adapter... in other words.. it's small and thin.I just happen to have a bright red cigarette type inline filter. The kind that comes with a hand pump. This SPA probe will now permanently live attached to that filter.
So now the one coming from MrodAir Mike will be a backup.

Read to the end https://www.gatewaytoairguns.org/GTA/index.php?topic=191696.0 (https://www.gatewaytoairguns.org/GTA/index.php?topic=191696.0)

The CS does things a little differently, they only regulate the control board, the motor runs at battery voltage. Probably a higher voltage motor than my Benji.

Best deal on big batteries is the harbor freight 20v 12ah, unless you have other tools that can use a big battery. You could get other voltage converters if you had 40 volt tools, or 60 volt tools. Keep a fair bit of overhead on the converter, these cheap ones tend to overheat when run at full load, 40 amps should be enough for most of these little compressors.

I know FB is not for everyone and a lot of folks want nothing to do with it.  I'm not a big fan either, however, this morning I found the GX Pump FB page and sent them a message about parts availability for the CS4.  To my shock and amazement, I received a reply within minutes and was told parts are currently on their way to the U.S. warehouse and would be listed on their website once they are available.  So, anyone with questions, if you use FB, you may want to message them there, seems they monitor that more than e-mail...  Also, I based on the response, I believe you'll be dealing with someone from the U.S., not China!

Title: Official thread for GX-CS4 Compressor
Post by: GadgetX on May 27, 2023, 11:14:58 AM
Since this thread has got quite a few responses I am assuming it is the official GX CS4 GTA thread.

I was lucky enough to get a CS4 finally after 3rd try through Amazon.  There is now a $50 coupon off on Amazon.

A few things I have noted since getting the CS4.

1. I got the 4 year unlimited warranty through Amazon

2. Finding a 7 PH Antifreeze is not easy.  Most don't list PH.  I have experience with Tesla Performance Raven and there is Dexel G48 antifreeze which is 50/50 mix and has a PH of 7.1

3.  The $700 compressor does not come with much in the way of manuals.  Google Roningrips.com for some good info.

4.  Before running MUST FLUSH/CLEAN and FILL the water tank and lines as there is debris in them.

5. Buy a hour meter and temp probe for your own sanity.

6.  Only turn grease pit every 4-6 hours of operation.

Will report back later with info on how long it takes to fill a 44 CF bottle from 3000psi to 4500 psi.

Well I am not having any luck...

I wanted to buy from Amazon which you can buy a 4 year protection plan with compressor

1st Try - They sent a GX CS3 compressor which I returned
2nd Try - Never got a compressor which Amazon refunded my money
3rd Try - Received a GX CS4 compressor which I meticulously setup and failed on just filling the service line with dead head.

I have not received any replies from manufacture on a half dozen emails requesting help.  Requested a free return from Amazon.

So as soon as I hear back from GX, I will try one more time.

Understood!
But Bill' question was " Did you keep the motor running?"

It seems to me that running the motor (and therefore running the alternator) makes a huge difference in power output.
Also
Did you try running plugged into an AC wall outlet?

Also, the GS compressors don't have the option to plug straight into 110v. They either connect to the car or the transformer.

 I have one of the cheaper transformer 12v compressors, and unless you have a large battery, they do not get the best performance with out a battery boost of some sort.

Post by: GadgetX on May 28, 2023, 11:04:52 AM
Ok guys I even tried a Deep cycle 12v boat battery.  The compressor runs and as you noticed it slows down and finally stops 180bar on AC adapter that came with it.  On the boat battery it starts to slow down 150bar and finally almost stopping around 230bar and the wires were red hot.  I live near Paul and his has a steady run until it hits the stop bar setting.  I had him listen to mine and he said his does not change rhythm slowing like mine.

Post by: Rat Sniper (AKA: PaulT58) on May 28, 2023, 11:51:35 AM
After talking with Mike and listening to his compressor, there is definately something wrong.  Mine will maintain a steady rythym throughout the fill cycle.  The gauge will slow considerably after it hits the tank pressure, opens the valve and starts filling the tank, but the rythym of the compressor never changes.  The rythym of the motor/compressor of Mike's slows considerably as the pressure grows.  Something's definately not right with it!

I can't believe the problems he's had trying to get one of these CS4's through Amazon!  On his first order they sent him a CS3.  The second never arrived and now the 3rd is defective!  What's odd is these are sold on Amazon by GX Pumps, so you'd think they were coming from the same warehouse!

It's about time to sttike up the band ad we all sing along!

LOL!  Well, at least I got the scope and it was the right one, it just hasn't worked as advertised!  They are getting one more chance, strike 3 and they're OUT!   :P

I read about another simular issue and GX Pumps asked if they had turned the grease pot, stating that doing so before the 4-6 hour intraval had passed would cause it to slow down.  Not sure if that is the problem with Mike's or not, but if the Grease Pot knob was turned, it was done at the factory before it was packed and shipped.  Hopefully his next one will be a keeper!

There is no grease pot on the CS3 and the one you have is one of those that was converted to oil bath.  You just have to drain the oil and refill it to the edge of the opening.  As for the interval, I hove no idea, but it probably would hurt to remove the cover, open the fill cap and inspect to see if it's even dirty.  That was a spare, so the oil is probably like new.  It was only used infrequently to fill my air guns with smaller air cylinders.

My personal experience with compressors is so mediocre compared to what I see written online. I almost wonder if half of what I’m reading is bs.  I would love to get one of these, but I fear I will have more luck like I’ve had so far and it will just be another crappy compressor that’s going to underperform compared to everything I’ve read.

Seems like these compressors are all a huge crapshoot.  I’ll probably end up ordering one of these soon things and it will probably end up working for about eight hours or something.

It pumped my Scott's 45cf tank from 2800 to 4500 psi in less than 40 mins.  It is actually quiet enough that we could be in the room with it talking and such.

Glad to get the 4 year protection plan from Amazon.

With what you went through to get a working one, they should send you a free one as back-up!  LOL!

I posted in the Bargain Gate, but in case you missed it, GX Pumps has the CS4 on sale again for $659.99 and the coupon code GX10OFF drops it to $594.00.  When I ordered mine, they were not charging sales tax and shipping was free, so it's now actually cheaper to purchase direct instead of through Amazon.

It's less than that now, they have it marked down to $629.99 with a $35 off coupon, but you do have to pay sales tax through Amazon.  The advantage of Amazon is the ability to get a protection plan, if you want the peace of mind.  Although I do feel the CS4 is built very we'll (when done right the first time) and should last.  There are also a lot of maintenance videos on YT and it seems to be fairly easy to work on.  With the temperature gauge and hour meter installed, I'm keeping a close eye on mine and hope it lasts a long time!
