  • This CS4-I 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 6.8L gas cylinder. Note: For the first use, it must be filled with 500ml of neutral distilled water or antifreeze ( PH is about 7). Note: 1) Be sure to add neutral antifreeze if it freezes in your area. 2）:Do not turn the grease knob until after 6 hours of use, otherwise will cause bad performance. then turn it one turn.                           
  • 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.                                          
  • 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 which never needs to be replaced, so you don't need to buy other external oil-water separators.                                                                                         

  • Please read user manual carefully before turning on compressor. All GX pum          p come with 12 months warranty service and life time technology support. 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 startin

  •  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. 
  • warm tips:  when filling a bottle which has pressure inside, such like 3000psi at beginning, if you want to fill to 4500psi .  1, Hook compressor hose to the bottle , leave bottle valve closed and start compressor. 2,when the compressor gauge is higher than the bottle pressure, open the bottle valve.

  •  

    • Pls keep in mind the important information when you received.          
    • 1. Note: For the first use, it must be filled with about 500ml of pure water or antifreeze before you turn on power. Be sure to add antifreeze if it freezes in your area. Otherwise, will cause damage ! ! notice : when switch on the power, the water pump will work first. be sure to check if the water flows from the upside hole in the water tank into tank.if not flowing, pls contact with us and don't press " start" button to use.
    • 2. Do not turn the grease knob until after 4-6 hours of use, then turn it 1-2 turn. we added before factory. Afterwards, when the speed slows down, turn it around again. After the break-in period, there is no need to add grease any more if speed is normal.
    • 3. 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 next starting.
    • 4. warm note: This CS4-I model was designed with 2 stages of check valve inside. When working, it does not leak. but after turn off power, it may leak pressure from the second stage check valve. For example, 300 bar drops to 200bar in several minutes. This is normal and please don't worry.

     

    • This CS4 compressor supports the max design pressure 5800psi/400bar, but it does not mean you can fill the max pressure anytime. Almost all pcp tanks and bottles only support 4500psi/300bar as the service pressure to avoid the safety problem, although they state the burst pressure can be over 50mpa/500bar. As a result, the burst disc coming with compressor only support the 350bar as the burst pressure. If you fill over 350bar, it will be blown. If you really need the higher pressure, pls contact with us to buy 400bar burst discs.
    • 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.

    Steady, quiet, cool

    I bought the CS4-I to fill small 3 liter size tanks. I have a CS3-I and I liked that for filling my air rifles (up to 500 cc), but I did not want to stress it to fill larger tanks. The CS4-I is so much quieter compared to the CS3-I. The controls are easy to use, and the pump is easy to set up. I did take care to make sure I had sufficient water in the radiator, and flushed it out a couple of times, and made sure to work out any bubbles from the system. On my compressor it did take some time to figure out the automatic stop settings. When I set the controls to stop at 310 bar, the compressor would stop at 300 bar. So I recommend doing a manual fill, shutting off the compressor with the adjustable stop needle to figure out the setting the first few times you use the compressor. Also I use a small flashlight to double check proper water flow. As the compressor and water heat up, the sight glass gets difficult to see through with fogging so a flashlight helps.

    So Far So Good

    I have only had my cS4.I about a week. I filled my 90ci bottle from 0 to 4400psi in 26 min and topped off my 66cf bottle from 2750 to 4400 in 1H12M. It is a joy to be able to fill my bottles inside vs outside with the YH. Plus I dont have to wear ear plugs anymore. Only time will tell for long term use. I hope the next generation of GX pumps add a hour meter and temperature meter. Outside of that I can not think of any other changes at this time.

    BEST option for larger tanks

    Hands down this is the BEST option to purchase if you use larger tanks such as 4500 psi / 90 cubic inch. Quiet enough to use indoors too!
