Can anyone tell me if the GX CS3 requires a watercooling bucket and pump like the yong heng or will it just run fine as is? Also is it possible for a compressor like this to fill a 75cu ft tank? Maybe with breaks foe cooldown or something?

It does not require external water cooling. Filling a 75cf carbon fiber would be a stretch. It takes 7.5 minutes to fill a 480cc carbon fiber from 1800 to 3500 psi. Not sure I would live long enough for it to fill a 75cf to 4500psi. It’s primarily designed for direct to gun or MAYBE a guppy tank, if you’re patient. There’s no doubt in my mind people have or will fill 75cf’s but should do so with timed breaks and maybe additional forced cooling.

Taken from manufacturers web page:
- ☆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 ( only suggest the max 1.5L) as long as the compressor is allowed to cool.

I filled a 2 liter tank from zero — 8 minutes run, 8 minutes just fan. Took maybe 6 or 7 cycles but I split it up into 2 nights.
I top that same tank off regularly 230 bar to 300 bar in 2, 8 or 9 minute cycles

I have a yong heng and the cs3. I cycled the cs3 for the longest time to fill my 74cuft. Have a big ol filter to keep things dry. I used to do 20 min run, 20-30min cool. Worked like a champ.

I have a GX CS3 that I bought to fill my first PCP gun which has a 550 carbon bottle. It works fine for that, but when I got a 60 minute 88 cubic foot SCBA tank, I didn't even try to fill it with the GX, buying a Yong Heng for $235 (almost half the cost of the GX) instead. In hindsight, I would probably have gone with just the Yong Heng and the SCBA tank, though it is nice to have the 12 volt compressor for long trips when I would likely empty my SCBA and as a backup for filling guns directly if / when the YH fails.

I got one. Filled a 6.8L tank from zero to 4500. I would run for hour cool for hour till 3000psi then 30min run and hour cool to 4500. Once filled I top off as needed. fill direct to guns as well.

From all the reading I have done I would say a compressor like this will do it but is a far cry from ideal. It really isn’t what it is designed to do. You will wear it out. the nearest dive shop here is 30 min away. I could probably drive there and back multiple times in the time it would take the cs3 to fill a big bottle. I would really just stick to filling guns with it.
