Review: Works very well. - At first, I was planning on getting one of those many $200'ish pumps readily available on desertcart. Many even look a lot like the $500'ish ones reputable airgun supply companies sell as their entry level "branded" recommendations. Upon further research, I decided to spend more to get significantly better specs and happy that I did. This one lists a MUCH longer run times (like over 5 hours, the others are like 10-15 minutes at a time), so it CAN fill bottles (still skeptical so not likely to be used as such for me). It is also significantly quieter (based on online reviews and videos of the others). Its noise is literally a FRACTION of even my regular air compressor for cars. It doesn't come with a temp gauge, like many of the other cheaper versions, but this one is water cooled - so it probably doesn't have a heat issue (definitely not even getting "warm" from my own uses). I'm not sure if it comes with a water filter (claims to have one internally) so I got a separate filter (from them). Specs are overkill for my intended uses (direct fill of air guns), but my gun has a max fill capacity of 3 bars, and this one actually is capable of going to 4 bars (the cheaper ones are all 3bars). This might have been the only one I've found that is specced to 4 bars at this price point. Works exceptionally well, doesn't rattle like its overworking itself, is quite enough to use in the house, and appears to have a good build quality. I think the cheaper ones may be a good alternative to the hand pumps (some actually costing the same surprisingly), but this one appears to be built to last a bit longer (especially if intended to be used casually like I am). Replacement parts seem to be available (but at this price point, I wouldn't be disappointed to have to replace after several years of use). I did have an issue with the water filter I bought separately (hookup error) and the support was immediate, real time, and helpful (same company), so the company has some credibility as well.
Review: Good Quality for the money - I purchased this as a backup for a model just below this one. I have about 50 hrs run time on the old one when I blew out a pressure disk. I changed out the disk but had poor performance so I decided to try this new unit. Wow, it is quieter and seems to pump just as well or better. I use this at home, so no need to hook up the transformer like the old unit. Later went back to trouble shooting the old unit and found some seals on my service line and connectors had blown. Replaced seals and now have 2 excellent compressors. So when performance starts to decline, check your service line seals. They will probably be the first thing that fails on this well made compressor.

## Features

- GX Patented Design :GX features an exclusive four-stage compression system paired with an integrated water-cooled compressor structure, powered by an genuine 350W high-performance motor. It is very stable when working, and it is very quiet with only 70db. 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 distinguishes it from others, which merely add water circulation devices to small shoebox-style compressors on market.
- A water tank and a grease tank are designed on the top of the airgun compressor. The excellent cooling can achieve 5 hours of continuous work . Note: For the first use, it must be filled with neutral distilled water or antifreeze ( PH is about 7). Note: 1) you can only add antifreeze if it freezes in your area in winter. 2）:Do not turn the grease knob until after 6 hours of use, otherwise will cause bad performance. then turn it one turn every worked for 6 hours. The new version now includes a hour meter.
- 15% Faster Filling Speed: Filling 0.5L tank from 3000Psi to 4500psi ,only needs 4-5 minutes. Filling 0.5L from 0-4500psi, only needs 14-16 minutes. but filling 6.8L bottle from 0-4500psi ,will need 2 hours and 40 minutes . Notice: CS4 and CS4-I are mainly used for high pressure, small gas cylinders below 6.8L, especially PCP. It is not recommended to fill large gas cylinders. Otherwise, you can choose 5K1 and 5K2.
- Built-in 110v to 12V DC Converter: Compared to the GX E-CS4, the CS4-I has a built-in converter for greater convenience. You can use car battery or household outlet as power supply. The machine is also equipped with a built-in oil-water separator .Suggest to buy GX professional external filter if you need enhanced filtration performance..
- Please read user manual carefully before turning on compressor. Quick connector : M10*1, 8MM female connector. Product size: 11.8*6.1*12.4 inch , weight: 29lb. ATTENTION: when filling is complete, please close the bottle valve first (when filling bottle) and then open compressor's bleed valve to release line pressure . All pressure must be released from compressor before starting. First confirm the maximum safe pressure of your gas cylinder, do not over-inflate, otherwise it will cause safety problems.
- Note: when add coolant first time, add full tank, turn on switch (don't press start button), water pump will run, coolant will flow into inner water pipes, then keep adding more coolant until water tank is full. Package includes: CS4-I pcp compressor, filling hose, 12V dc cable, 110V ac cable, user manual, accessory bag.

### ⭐⭐⭐⭐⭐ GREAT QUIET EFFICIENT COMPRESSOR
*by C***M on September 7, 2025*

Excellent compressor! Has all the bells n whistles. Fast fill time. 68ci tank fill from 0-4500psi in 25 minutes. Have filled many tanks with great times. Can fill for 5 continuous hrs with no down time for large tanks. Big perk is it's extremely quiet! In addition has a grease pot which allows you to turn knob every 4-6 hours to lubricate the pump. Awesome feature! Have owned quite a few cheaper compressors n by far this one is superior. Costly but you get what you pay for. If your on the fence about buying this compressor it's definitely worth the cost. I couldn't be happier! Has good instructions with an itemized parts list which is great for if n when could need repairs. Don't anticipate that for a long time. Very pleased with this purchase! GREAT COMPRESSOR! Also has auto stop setting ability with a back up setting to your setting. Pump does not get anywhere near overheating due to the onboard water tank for great cooling of pump.
