Review: Trusty Little Pump! (3 Years So Far) - This is good pump and it is relatively quiet. It has worked well for three years now.
Review: Excellent PCP Air Compressor! A VERY Happy Customer for my Air Rifle Fun! - Excellent GX CS3 PCP Air Compressor! I have used several different types of PCP air compressors with my friends and never found one that I wanted to invest my money into as some were too loud, some too slow, some too messy with oil and or water and most were all too bulky and too heavy. Add up all those negatives and you can understand why I was not happy to pay for any of those. Then I found this one! The GX CS3 PCP Air Compressor! No water hassles and no oil hassles (it has built in fans to cool it). Supposedly not too loud (it was not, I could easily talk to someone in the same room). Supposedly could be used from my 110v house socket (Yes, it worked great as it comes with an included transformer to run from my 110v house current!) or from my car battery (Yes, that too worked great as it has wiring and clips to attach right to the car battery). Did I mention the auto-shutoff yet? Yes, it has one and it is adjustable! Did everything work as hoped. To sum it all up as quickly as possible, YES! It worked flawlessly with every feature that I mentioned. The craftsmanship was impressive. Also, one of the best features is its size and weight as it is small and light and extremely portable. Easy to lift, easy to carry, easy to set up with running from either the house or the car. I held off reviewing it until I received it and used it several times, so my above comments were after I had used it on many occasions as my kids and my wife all have PCP air rifles! Upon receiving it I had a feeling that I was going to love it. The packaging was triple secure, meaning it had 3 strong layers of boxes, foam, ties, staples, you name it, this thing was packaged excellent. The instructions were also good and easy to understand. Tools and small supplies came with the unit which were nice additions. I can keep everything together and know that I have all the tools if needed. Using it on PCP air rifles, the speed of filling up the tanks was excellent for its size. Much easier than all the messy, heavier ones and much easier than manual pumps. Soon I will have some photos to post and a small video. Go for it, you will be quite happy with all of its capabilities and ease of use, especially with being so lightweight and portable. I usually do not write such long reviews but did so as it made my air rifle adventures a lot more fun for me and the family! Enjoy!

## Features

- ☆Why Choose GX: All GX compressors feature genuine specifications, such as power output, unlike others labelled as 350W yet failing to reach even 250W in reality. Most importantly, GX holds patented exclusive compression technology, such as the addition of roller bearings at the top and bottom of the connecting rod, allow for better movement and less wear on the rod and wrist pin, significantly extending service life and enhancing performance under high pressure.
- ☆Setting the Autostop & Built-in Oil-Water Filter :The filling of a rifle or pistol is hassle free with an auto shut off that the user sets at the desired pressure. This eliminates the user from having to watch the fill pressure gauge as the compressor does its job. It also features the moisture filter which will be more safe .GX pump has the best motor and compression structure to keep more stable and long life service.
- ☆Oil-Free & Water-Free & Built-in Fan Cooling for Long Life :This pcp compressor does not need oil, clean and hygienic, easy to operate.This will save you a lot of energy in future using. This is also an ideal choice for airgun and scuba tanks ( not certificated). Suggest to buy GX professional external filter if you need enhanced filtration performance.
- ☆3 Type Safety Device Design & Convenient Wire Spool Design: Adjustable pressure gauge , safety valve and burst disc valve makes this air compressor pump more safe. With the wire spool, you don't need to worry about the wire winding and it also looks great. Note: we have applied U.S. Appearance Patent for this . ATTENTION:Please release the bleed valve first after turning off the switch every time, and do not start it when there is still air pressure inside (even during the cooling down cycle).
- ☆Test Inflating Speed : This pcp compressor was designed mainly for inflating less than 1L tank. Fill a 190cc tank from 1800psi to 3300psi is a swift 2:30 minutes; Filled a 480cc carbon bottle from 1800psi to 3500psi is in a mere 7:30 minutes. The duty cycle of the machine is 30 minutes run / 20 minutes cool. This allows for filling of larger tanks ( suggest max 1.5L) as long as the compressor is allowed to cool.
- ☆Car 12V DC or Home 110V AC Power Choice : This pcp air compressor can be powered by the 12V car battery , also can be powered by the home AC outlet with the included 110V-12V converter . This will make this pcp air pumb more usefull as you can use it anywhere.

## Questions & Answers

**Q: How does fill speed compare to Yong Heng?**
A: Takes me 25 mins to fill my ninja 77/4500 tank

**Q: If and when this compressor needs to be rebuilt is there a rebuild kit available and if so were can I purchase it and how.**
A: Mine was shipped with extra o rings, screws, collars, small wrench.  But the manual mentions nothing about rebuilds or replacing worn o rings. The manual is in "Chinglish" so it is poorly translated English. 

I think if it leaks or fails to work ur best bet is to see if Amazon or the manufacturer can facilitate some repair or replacement otherwise try fixing it DIY. 

For the low price even if it breaks down in 5 or 6 years u got ur money's worth.

**Q: So i’m being told this is the updated oil bath version and not the old grease version. so then, how often do you need to change the oil?**
A: There is no oil change required.  It's totally maintenance free.

**Q: Thx for helping with my question. Since the water and oil separator filter is built in, would you recommend putting one in the air line ??**
A: Yes, I would highly recommend putting an additional filter on any air compressor as almost every air compressor eventually puts water inside your pcp airguns.

### ⭐⭐⭐⭐⭐ Great portable affordable compressor!!!
*by A***R on March 5, 2020*

I use this product solely to fill my PCP airguns it's a great little compressor the only issue I have is it supposed to come with grease so you can service it after 50 hours of use and I just open the second one and there's no grease other than that satisfied.....Update... I e-mailed the seller about the grease issue. I received a prompt response informing me that the compressors have been updated and no longer require you to service them with grease after 50hrs of use or anytime after that. It seems the oroblem was that the updated compressors wete being shipped with the old owners manuals. They were very apologetic and assured me that I shouldn't have any problems with my compressor and instructed me not to try to service it with any sort of grease because it would be detrimental to the workings of the compressor. I must say they set my mind at ease. I mean this is a 4500psi compressor so you can understand i was a little worried about keeping it in proper working order. After receiving their e-mail and corresponding with them I must reevaluate and give this little compressor a full 5 stars. It exceeds my expectations and performs better than described. I use it with my Benjamin Bulldog and it fills from 1500 up to 3000psi in about 8min. Not only that its relatively quiet and highly portable. I've run it off both my car battery and the wall outlet converter and it works great off of both. The other great thing is it came with a quick disconect already attached and it fit right on my gun. Oh and it has an automatic shut-off you can set so you don't have to babysit it while it fills. If you're looking for a good, self contained, portable high pressure compressor at a great price this is it.
