Keeps Cool When In Use 😀 - I was looking for a better replacement for my Yong Heng compressor and purchased a GX water separator filter and noticed the filter to be well thought out and built like a tank. I was impressed so much with the filter build and performance I decided to purchase a GX GS4 compressor. Upon opening the packing crate I removed the compressor and read the instruction sheet. Imagine an instruction sheet with a compressor. (Some do-not. have one). I live in Utah wher winters get cold. My compressor would be in my shop so used a 70/30 mix of green antifreeze with distilled water and had a 7 ph factor. I bought the compressor to mainly fill my 6.7 L tank. I started the fill procedure as per directions such as opening the vent to let compressor start then closing vent to prevent the compressor from starting under pressure. 3.4 hours later my carbon fiber 6.7L tank was full at 4350 psi. I shut of compressor but let the coolant flow through the compressor to cool it down. Over the time filling the tank it never got really hot as the coolant radiator and fan worked great to keep it cool. It has a pressure shut off and a back up shut off for safety. The compressor is fairly quiet in its operation. The quality of the build is amazing. It is really built strong and for reliability. It does not struggle to fill the 6.7L tank. Most of the other tanks need a cool down period filling tanks that size. I am not only impressed with its capability, but also the machining, and quality of the unit. The unit will compress air to 5800 psi and has safety devices to keep excess pressures from causing issues. This is a PORTABLE unit and weighs 29 lbs and can run on 12 volts or 110v. It uses 345 watts with compressor on. I tried to save money on lesser quality compressors but they did not perform well or died within a few months. This GX compressor is not that more expensive. It truly is a well made compressor of quality workmanship and design with safety systems and pressure back up switch (2) to keep you safe. I appreciate the safety as well as the unit. NOTE: If you have any high pressure compressors look into the GX Drain Filter as it by far is the best strongest oil and water pcp filter out there. I am not affiliated with GX but after buying the compressor and filter I am and will be a GX customer. Dr.Dave. Utah. UPDATE…. I have been using this compressor filling my AirForce Texan LSS .457 an AirForce Condor SS and Air Venturi Avenger and a SCUBA tank to fill my other pcp airguns out in the field. I have had no problems with the Compressor. I did add a timer to know when I should change oil in the compressor. I would buy this compressor again as it is a workhorse and is quieter than most and coolant cooled so no overheating issues. VERY HAPPY with purchase. Update: This compressor works just like it did when new.. No, Problems or even small issues. Has already outlasted my Yong Heng compressor. I do use the GX Coalescent filter that really stops water from getting into gun or fill tank. I added a battery operated timer to it. That filter is really innovated and works GREAT !!! Review: GX pump review - Solid Reliable and Durable - I bought this in early 2024 and have used it almost every two weeks since the purchase. I wanted to give it time since I've had several similar pumps fail within a year's time frame or within a couple of months. This unit although it was a little bit more expensive was well worth the money. This thing is Rock Solid so far and shows no signs of failures and has been extremely quiet and efficient. I would highly recommend this to anybody looking for this type of equipment. ## 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 compressor. The excellent cooling can achieve 5 hours of continuous work and can fill a 3L gas cylinder. Note: For the first use, it must be filled with about 300ml of antifreeze ( Distilled water is not recommended.). Note: 1) Be sure to add neutral antifreeze if it freezes in your area. 2）:Do not turn the grease knob until after 4-6 hours of use, otherwise will cause bad performance. then turn it one turn. Search "how to add coolant for cs4" on youtube to learn the correct steps. - 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. Filling 6.8L from 0 -4500psi, needs 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. - 12V DC input, you can use car battery or household outlet for power supply, equipped with 110V-12V converter. The machine is equipped with a built-in oil-water separator which is not a cotton filter and never needs to be replaced. This is an ideal choice for airgun . 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. - Note: 1， 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. 2，The new version has updated the timer and the minute readings, but the readings received by each machine are random. - Note 3: The panel has been updated with an overcurrent protection switch, which will cut off power in case of excessive motor current. In this case, operation needs to be stopped, the pressure relief valve loosened for cooling, and the check valve flushed with water should be attempted. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BLSS8T43 | | Additional Features | AC & DC Adaptable, GX PATENT, Portable, Quick Inflation | | Air Flow Capacity | 11 liters per minute | | Best Sellers Rank | #150,014 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #130 in Portable Air Compressors | | Brand | GX pump | | Brand Name | GX pump | | Capacity | 6.8 liters | | Color | Red+black | | Customer Reviews | 4.5 out of 5 stars 280 Reviews | | Hose Length | 19.6 inches | | Included Components | compressor, hose, 12V converter, 110v ac cable, user manual, accessory bag | | Item Dimensions L x W x H | 11.81"L x 6.1"W x 12.4"H | | Item Type Name | pcp air compressor | | Item Weight | 29 pounds | | Manufacturer | GX | | Manufacturer Part Number | GX-E-CS4 | | Material Type | Metal | | Maximum Power | 350 watts | | Maximum Pressure | 400 bar | | Model Name | GX-E-CS4 | | Model Number | CS4 | | Noise | 70 db | | Noise Level | 70 db | | Number of Items | 1 | | Power Source | Corded Electric | | Recommended Uses For Product | pcp compressor, paintball tank filling | | Special Feature | AC & DC Adaptable, GX PATENT, Portable, Quick Inflation | | Style | Portable | | Tank Volume | 6.8 liters | | Unit Count | 529.11 Ounce | | Voltage | 12 volts | ## Product Details - **Brand:** GX pump - **Noise Level:** 70 db - **Power Source:** Corded Electric - **Recommended Uses For Product:** pcp compressor, paintball tank filling - **Voltage:** 12 volts ## Images ![GX PUMP GX-E-CS4 PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa - Image 1](https://m.media-amazon.com/images/I/71VBEYX44QL.jpg) ![GX PUMP GX-E-CS4 PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa - Image 2](https://m.media-amazon.com/images/I/71fMqO4Tn5L.jpg) ![GX PUMP GX-E-CS4 PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa - Image 3](https://m.media-amazon.com/images/I/81nDRd4pnbL.jpg) ![GX PUMP GX-E-CS4 PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa - Image 4](https://m.media-amazon.com/images/I/71VymmBb1QL.jpg) ![GX PUMP GX-E-CS4 PCP Air Compressor, 350W Powerful Motor,Max 5800Psi/40Mpa - Image 5](https://m.media-amazon.com/images/I/81Mz-+F3KCL.jpg) ## Questions & Answers **Q: made in usa?** A: No, I like to buy things made in the USA but unfortunately this product is not. this is a great pump and does the job well,my first one and really happy with it **Q: When to change out water or antifreeze? 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 ### ⭐⭐⭐⭐⭐ Extremely well thought out and built like a tank !!!!

As an avid air gunner, I was in the market for a reliable, high-performance pump that could handle my needs, and this one has exceeded my expectations. One of the standout features for me is the ability to pump up to 400 bar. I own a Huben GK1 air pistol that is rated for up to 350 bar, so having that extra headroom is fantastic. I can now fill my pistol to its max capacity without any issues. The compressor handles the task with ease, and I'm impressed by how quickly it can fill even my larger air cylinders. Another feature I really love is the water cooling system. I've had troubles in the past with other pumps overheating when filling larger volumes, but the GX-E-CS4 stays cool and composed even when I'm filling my 6 liter bottle. It's so convenient to be able to top up my air reserves without having to worry about the pump conking out. The price of this compressor is also amazing considering all the functionality and performance it offers. I was a bit hesitant at first, but after using it extensively, I can say with confidence that it's worth every penny. Finally, I have to mention the stellar customer service I received. I had a minor issue pop up, and the company was quick to diagnose the problem and send me a replacement part. Their responsiveness and willingness to stand behind their product is refreshing. Overall, I highly recommend the GX-E-CS4 to any PCP air gun enthusiast. It's a game-changer! ## 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.ae/products/504048138-gx-pump-gx-e-cs4-pcp-air-compressor-350w-powerful](https://www.desertcart.ae/products/504048138-gx-pump-gx-e-cs4-pcp-air-compressor-350w-powerful) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-08-30*
