Seeking advice: Home-filling a 100 cu ft 4500 tank

Jump to latest Follow Reply
There are a number of variables to address when attempting to answer "what to get" type of questions. First on my list is budget. What are you comfortable spending to get where you want to be? Next would be the size or foot print you can deal with for the compressor. Another question to ask yourself is how much time you are willing to wait for your bottle to fill. I have a two (2) GX compressors: 1 is a CS3 and the other is a CS3-1. These little compressors have served my needs but should not be utilized to fill large tanks. As stated by WorriedMan, the CS4-1 or the larger E-5K2 should meet your needs with caveats.

I was under the impression that a 100 cubic foot tank at 4500 was "very large". Is the CS4 still a good option for this? I don't need it to be portable.

Regarding budget, cheaper is always better but I don't want to sacrifice quality for it. I look for "good value" over the cheapest thing I can find. I did some looking around and it looks like $1k-2k might be the range. Unless of course the CS4 can handle it.

I use a GX CS4-i to top off 9 liter tanks. The compressor is perfect for this task. One other member of this board has used the same compressor to fill a 9 liter tank from zero. It took over 5 hours of continuous running as I recall. Obviously, the compressor will fill from zero but I don't think it will last long if driven this hard.

Been running one pushing 2 years.
Fills a 9L from empty in about 75 minutes.
Don't use anything special, just synthetic type 46 oil and a 5 gallon tank of water. Dual filters, one traps most of the water the other dries the air.

Replaced the batteries in the temp gauge 3 times. Had the circuit breaker on the motor pop once on a 90+F day.

It may need a high side rebuild soon, seems to be slowing down. But I use it a lot to keep all my tanks topped up (3 9L, 2 6.8L, 1 3L). Given how often I degas and fill I usually top off 2 of the 9L and 6.8L over the course of a weekend. Usually drop ice bags in between fills to cool the water back down.

Didn't used to but Amazon ad for GX-CS4i now states not recommended for filling 6.8L tanks, or larger. Recommends single, or double, cylinder versions of GX-CS5 for 6.8L, and larger. WM

I shoot from home pretty much exclusively as well. I have tanks but rarely use them. I have the GX-CS3 e compressor and I attached the power supply to the outside of the case. I fill guns directly with it and it's portable enough to take with me to places that have a power source. No bulky water cooling buckets required.
As for hunting... my guns get 30 or more shots per fill. If you need more than 30 shots on a single hunt then I would like to go with you one time because you really found a honey hole. That or you need alot more practice to hone your skills.
Sometimes I tether to a tank for long shooting sessions at home. I don't need 4500 psi in a tank for that either. Regulated guns only need something above the reg set pressure for lots of shots from a large tank. Non regulated gun typically have a "sweet spot" range in their bell curve and a tank filled to that level will also get you hours of accurate fun. I use a Yong Heng for that duty.

The GX cs4i can run and fill a 9 liter bottle. This within its operating guidelines.I have the GX and the Tuxing TXed 042 , happy with both for their different path for the same outcome.
The GX works slow and cool but can last a long time The TX gets things done fast and Hotttttt….but can be controlled by cooling. I’ve ran the GX 5 hours at a time. Twice. I keep a 3 a 6.8, and a 9 liter filled at 4500psi. I have upgraded cooling on both machines effectively. Neither machine requires much mechanical abilities and parts available
TX a couple hundred cheaper than GX
