12/4/23 UPDATE: now have over an hour of time on this, many fills later with zero issues so far. Filling my crown to 250bar every time and stopping with the auto stop perfectly. Hopefully this continues!
I recently got back into PCP's and decided its time to ditch the hand pump and get a compressor. I did a ton of research before choosing but ended up going with the GX CS4 mainly due to the liquid cooling while still being portable.
This is my FIRST compressor and I am aware there are far more expensive and better options for some, this was my choice. I am posting this so those looking into THIS compressor can get an idea about it. So any positive/negative feedback is welcomed but please be sure it pertains to THIS UNIT ONLY.
Yesterday I finally got the CS4 in and here are my initial impressions:

Yesterday I finally got the CS4 in and here are my initial impressions:
- Design Quality- Seems very well built overall, I didn't expect it to have a premium feel but it seems (initially) to be built respectably. I really like how the inverter is exterior and separate of the unit. I saw a lot of complaints about this but to me this makes more sense. If I want to go portable, why would I want to lug around the inverter inside the unit? Its added weight, plus its harder to get to in the event I need to maintenance/replace. The 12v cords for using it in portable mode seem to be quality lines, although not thick like jumper cables would be. The switches/buttons/gauges all make sense and I really like how you can switch the pump on, and or leave it run after you are done filling to help circulate and cool the unit. The gauges have both Bar/PSI so it makes it easy to reference, some units I was looking at did not have that feature so that's a nice touch. It has rubber feet on the bottom and on the side as I imagine you can lay it over but I am not sure how that would affect (if at all) the water pump. NOTE: This unit DOES have a burst disc by the grease pot which I read some smaller compressors do not have. Definitely wouldn't operate one that doesn't have one, but maybe that's just me.
- Initial start up- Obviously read the manual prior to doing anything with a high pressure unit like this, but also double check all the screws and fittings and such just to be sure its going to be a safe start up. I am not a safety Nazi by any means but high pressure and loose objects usually tend to become projectiles. At any rate, I started by dumping the fluid that was in the water revivor as I received it. I read a few blog posts on this unit before receiving it and that seemed to be the standard as these are all QC'd for function before leaving the factory. There looked to be some sediment floating around so I just flushed it by pouring in distilled water, swishing it around and then dumping it out. Repeated this like 2-3 times and called it good. I refilled it will just distilled water at this point, however I do have the antifreeze on standby now that I have confirmed the unit operates correctly. I double checked the inverter was set to 120v (Do not forget that step) and then filled the water reservoir until full, next you need to start JUST the pump and the continue to till until the water reaches the outlet flow up top. Now I knew I was ready to test the unit.
- Did the whole start up process with the plug in the supplied air line and filled to 250 bar, achieved by setting the needles in the desired location. Then once filled I let it sit in the line to check for leaks...I had leaks. HOWEVER I checked the fittings and discovered it was the plug itself which was letting air escape and not the hose (confirmed by trying a spare hose I had on my hand pump). Decided its time to test it on a rifle and see what it can do!
- First gun fill: Xisico Sentry OG model- The gun was sitting at around 1200psi and I needed to fill it to 2200 psi for my current tune. I have no idea what size the air cylinder is but one of these airgun nerds will surely chime in
. Once again did the whole start up procedure (too lazy to write it out) and started filling the gun, it filled it to the desired pressure and stopped dead on the money in under 2mins. This to me was fairly impressive however I have never even seen an HPA compressor in action so maybe its just me. What was super surprising was the noise level of the this compressor, it was super quiet and very smooth sounding. It sounded as if it was barely doing anything and maybe thats due to such low pressures on a unit capable of much higher. Anyways it worked great and the sound was quiet enough you can run this inside no problem.
- Today and in the days to come I will be recording a video of it filling my Crown with a bottle on it to 250bar and see how it does. Overall I am really impressed and happy with the purchase however time will tell. My absolute main concern was not noise level, or time to fill, it was simply life expectancy. These things aren't cheap (at least to me) and I need/want it to work. I posted a couple pics of the unit (not the greatest lighting in my basement) and like I stated above, will have a video link shortly (not a youtuber so don't expect much) but it will show case the start up process and how it fills a larger bottle gun.
