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

Hi @kwaping
I was in a situation similar to yours. The dive shop that i normally go to fill my tank has had compressor problems and i wasn't able to get fills to 4.5k psi.
The next closest shop was 2x the distance, and i knew this would soon get tiresome for me to refill every week. I asked around, and did my research on compressors, and had my doubts about the longivity of the cheaper models. I asked Mike of team Centercut what their team used, and he replied the team has been using an Omega Air Charger for several years without any problems and he highly recommended it. I was hesitant at first since it is a big purchase, but i decided to make the purchase. I purchased it from AOA, and it arrived yesterday. Had 1 little problem with an air bubble in the coolant lines that prevented the water pump from activating. But once that was fixed, the machine worked fine. I don't know how quiet it is compared to other compresors, but it wasn't that loud. The compressor comes with a rebuild kit, and from what i was told, is not difficult to work on.
My first fill of my tank from 2200 to 4500 psi took about 45min..and i bleed it off every 5 min. I think the newer models have an automatic bleed...but that wasn't to important to me.
filled all my rifles and refilled the tank.
I believe i made a right choice, but only time will tell
Wish you luck on your future compressor

I'm still learning ..though everyone has mentioned a cool-down time after fills.
And allowing the pressure to build to equal the pressure in your tank before openning the valves.
mine has a manual bleed, so i bleed off a quick burst every 5 min
Open that box up!! Get to filling!
Why do you do the frequent manual bleeds?

I got the GX filter along with it, did you?
 
no gx filter on the Omega aircharger. not a big deal for me to do a quick bleed, i am always in the room while filling.
while mine is not whisper quiet, you can have a conversation without raising your voice
How is the noise level on yours?

Mine is silent so far.

Got it unpacked and all set up. I had the same "issue" as Mike did, with the coolant not circulating initially. I opened it up and checked all the wiring, thinking something came loose during shipping. Nope, everything was looking good. Then I remembered the air bubble thing. So I tipped the unit front-to-back about 20 degrees, and then back-to-front the same amount. After that I saw coolant starting to circulate, so that was a huge relief! If you buy one, just expect this to happen and skip the disassembly part.

Overall, this product has exceeded my expectations and I'm really happy I got it. It's fast to fill and remarkably quiet, way less than you would expect. I can't speak to longevity yet, but I have never read a bad thing about it online. I would go so far as to say this is the Cadillac of compressors, at a very fair price.
