Review: Great product. - Good sound compressor quite ,I use to fill a 5lt bottle with no problems ,would recommend
Review: Fills my 350 Bar air gun easily. - 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.

## 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. Product size: 11.8*6.1*12.4 inch , weight: 29lb. 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 . All pressure must be released from compressor before starting.
- 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.
- Note: Max design pressure is 5800psi, the burst disc may be blown up if fill over 5000psi. You can add 1 more burst disc from parts bag into the burst disc valve if need over 5000psi. Don't use tool to screw the burst disc valve nut too tight, otherwise the burst disc will be blown up easily. Just tight a little.

## 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.

### ⭐⭐⭐⭐⭐ Great product.
*by D***. on 12 December 2025*

Good sound compressor quite ,I use to fill a 5lt bottle with no problems ,would recommend

### ⭐⭐⭐⭐⭐ Fills my 350 Bar air gun easily.

It’s is very quiet compared to my general purpose compressor so I am very pleased with my purchase.

### ⭐⭐⭐⭐⭐ A brilliant investment.
*by A***R on 10 March 2025*

What can I say... nothing short of brilliant. Very quiet indeed. Easy to operate and straightforward controls. I like the double check on the pressure setting device. I just checked it with an external pressure gauge - 230bar - spot on. Filling is easy, I've opted for deionised water and a drop of antifreeze which has anti-corrosion properties - just to be extra careful. Filled my 280cc bottles from empty in no time - used to take me ages by hand.
