This compressor is without doubt a big step up from the traditional "shoe box" style compressors which can burn themselves out in a very short time. The CS4 being water cooled runs very cool and I have found performs very well when topping up my 7Lt dive bottle, taking it from 200 bar to 300 bar in only 39 minutes and never exceeding 37 deg C. It is early days but I get the impression that this machine will last for many years. Review: Good and quiet - I only used once! Works very well ## Features - This CS4 PCP compressor has a new upgraded 350W motor , and adopts four-stage compression technology. It is very stable when working, and it is very quiet with only 70db. Maximum filling 5800Psi/40Mpa.Notice :First confirm the maximum safe pressure of your gas cylinder, do not over-inflate, otherwise it will cause safety problems. 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. - A water tank and a grease tank are designed on the top of the compressor. The excellent cooling can achieve 5 hours of continuous work and can fill a maximum 3L gas cylinder. Note: For the first use, it must be filled with 500ml of neutral distilled water ( can not contain impurities such as minerals )or antifreeze ( PH is about 7). Notice :Do not turn the grease knob until after 6 hours of use, otherwise will cause bad performance. then turn it one turn every 6 hours. - 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. - 12V DC input, you can use car battery or household outlet for power supply, equipped with 220V-12V converter. The machine is equipped with a built-in oil-water separator which never needs to be replaced, Suggest to buy GX professional external filter if you need enhanced filtration performance.. - Please read user manual carefully before turning on compressor.

ATTENTION: when filling is complete, please release the bottle valve first (when filling bottle) and then open compressor's bleed valve to release line pressure .

After certain amount of used or hours?** A: the instructions say to use distilled water, so you should check it and keep it topped off, but it should not need to be changed unless you see impurities in it **Q: Can you use this for mini 1.9l or full size scuba tanks and is an adapter required?** A: The manufacturer states you can fill a 6L tank and it can run 5 hrs. Continuously though I only used it to fill my 90ci buddy bottle. I never timed it but it takes about 15 min. To top my bottle off from 3k to 4.5k and works off car battery as well so topping off my tank at the range is a breeze **Q: How to get tech support about antifreeze leaking out the bottom after 1 fill?** A: I would just take the cover off and look for a loose hose clamp. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive performance *by R***T on 28 August 2026* This was not my cheapest purchase but I have to say that I am impressed with the engineering and build quality.

Works very well ### ⭐⭐⭐⭐⭐ Fills my 350 Bar air gun easily. *by D***H on 4 May 2025* I needed 350 bar for my air gun it this compressor reaches that easily with 50 bar to spare so it shouldn’t ever have to work to it’s maximum which must be a good thing. It appears to be well built and everyone that leaves a review is very pleased with them. £60 off at the moment is a bonus. It’s is very quiet compared to my general purpose compressor so I am very pleased with my purchase. ## Frequently Bought Together - GX PUMP CS4 Portable PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa, Water and Fan Cooling, 5 Hours Continous Work, 12V Auto Stop Paintball Air Compressor - Creation Core High Pressure PCP Hand Pump Air Filter Water-Oil Sparator with Female and Male Quick Connect for High Pressure Air Compressor Pump 30Mpa Blue - Maddog Paintball Airsoft Fill Whip Hose Extension 4500 Psi PCP - 36 inch Stainless Steel Charging System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/598355398-cs4-portable-pcp-air-compressor-350w-powerful-motor-12v-input](https://www.desertcart.hr/products/598355398-cs4-portable-pcp-air-compressor-350w-powerful-motor-12v-input) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-19*
