I,m thinking about getting a portable air compressor?

[Fly]

Well as long as I have been into this hobby never had a portable air compressor. I know this has been ask many times, but I
just need to ask . I have a hard time understanding how these units can keep from over heating, not being water cooled.
You that have them how long can I expect it to last? How many times have you used yours with out problems? I just must
get some info with out throwing good money on something that going to be giving problems. Thank you for your honest
opinions!

Glad you asked. If you are serious about purchasing a portable compressor my suggestion is to look at the GX brand. You will be able to find then being sold at Amazon, Ebay, AliExpress and even Walmart. I have a GX CS1 & GX CS1-I compressors that have served me over three years without being rebuild. The maintenance I have done is to clean out the bottom check valve regularly and then one time I opened each of my units up for cleaning and a relube job. There are videos and reviews of these compressors on YouTube with more than you might care to watch.

There are a couple of times each of my units will run 'hot' and need to be shut down with fans running for 10 minutes as a cooling cycle. I shoot twice a day and fill the rifle fired after each session. The units only run hot when the local temperatures rise and I am filling from empty due to tuning/ retuning my varioius guns.

3 min pump on ,3 min pump off fans on. Keep it cool and it will last a long time.

I got a GX CS2 earlier this year. I've filled my guns a couple dozen times with it. I filled my Avenger once from completely empty. But usually I am filling my P35s from 150 bar to 250 bar. Takes about 5 minutes if I'm using the GX filter. 3 minutes without. If has never gotten hot including the Avenger fill from zero. If you just use it for gun fills I don't think it would get hot. I think they recommend only using it for 30 minutes at a time. I have not gotten close.

The GX compressors cycle the piston much slower than my Yong Heng. They are also smaller. Both things help them stay cool. I think they are better engineered too. They are lubricated with grease and have ball and roller bearings. The Yong Heng is splash lubricated.

I also wanted portability so I got the CS2. It is the smallest and lightest. I got the normal one and then added a power tool battery setup for it myself. Materials were about $25. There is a thread. Now I can power it with my Milwaukee tool batteries, or a vehicle, or 120V if I am home. It's no frills with no auto shutoff and no switch on the cooling fans, they start when you connect power, but I like that. Does the job without the extras. But if you want more features there are other models. The CS3 is the same basic compressor with a bigger case covering things and auto shutoff. The CS4 is still portable but has water cooling and is a little bigger. It is supposed to be able to fill mid size bottles. I think it weighs about 40 lbs where my CS2 weighs 15.

Gx cs2 that is over 1.5 years old and going great. Parts are available and they are super easy to work on. I recently replaced the low pressure piston ring on mine even though it really didn’t seem to need it. I’ve run it many times through a larger sized tuxing filter for 15 min fills on a 500cc 300 bar tank. Takes it in stride.

The only other thing I’ve had to do was replace the fill hose. It ended up getting a small hole in it.
