I tether to the compressor and a .48l bottle.
It's an inline regulator by "Aqua Environment" Model 415-5000. These are sold by a number of retailers. I bought mine from NUVAIR.
I did buy direct from gxpumpofficial.com. I used the 10% discount code and paid $1659 for the E-K2 and the new moisture filter. (I have since received a small refund due to shipping taking longer than they expected.)
You will love it. GX makes great machines. I have the cs2 and cs4. Impressed with the way the cs4 tops scba tanks so I know the 5k2 will knock it out of the park. Gx is also now sold out of all the big machines and who knows how long it will take for them to restock.
I definitely will post a review, though I have nothing to compare it to. I didn't see any phone number listed, my guess is that they are Mandarin/Cantonese speakers and use translation software on emails. But if you send an email in USA time, you should have a reply waiting for you in the morning. The email people (maybe even a single person?) are very intimate with the details of the business, I don't have any concerns in dealing with them. In fact, I wouldn't be surprised if they helped a person out after the warranty period is over.
The first use on the gx4 was topping off a 6.8L or 45 min scba. It was below 3K psi…like 2800 or so. That top off took just a little over an hour. No breaks during filling. I now don’t let the tank go below 3200-3300 psi so the gx only has to run about a half hour max. I also fill to 300 bar not 4500 psi. This amount of air is good for me weekly. If you require a bunch more maybe the 5k1 or 5k2 would be best. I only shoot a cpl days a week for a little while each day.
Hopefully….they told me weeks ago the 5k1 would be back in stock in two weeks. By weeks I mean many more than 2…lol. The last time they were out they were out for quite awhile.
When I asked them about the 5K1, it was more than a month, but I probably asked that a couple of weeks before you did. I think a 5K1 would be plenty for me but I didn't want to wait.
Yeah, I certainly don't need a 5K2. Besides not wanting to wait longer for the K1, I also think getting an overpowered compressor might make it more durable and reliable. And hey, maybe I can start a tank fill business and have it pay for itself!
