What Compressor Are You Using Top Off At 300B?

[Sleestak]

My GX CS4 handles >300 bar w ease if I'm in no hurry (that's what the YH is for)

I also have a Hill Evo 310 that will fill to 310 bar but I would never use it to fill a scba tank (even though they say it can) It's the only compressor w which I would trust the auto shutoff and is my dedicated direct-fill compressor

I took a risk, I bought a tuxing twin and so far it’s been great. Seco 100 oil, and an extra filter besides the twin tower. I added an hour meter and let it run for 20 minutes with no load on it before it filled a tank. It’s pretty quiet and doesn’t seem to strain getting up to 300 bar. It takes 13 minutes to fill my 45 min SCBA from 3400 to 4500, that includes filling the twin tower and my auxiliary filter. Time will tell……..

My Tuxing twin finally needs a rebuild after 2 years of hard use. But top off for my 9L tanks was 20 or so minutes and was up to 30+ minutes.

I'm running my Yong Heng backup right now. About 30 minutes for top off.

I am also looking at that. Unfortunately it does not really like bottles. And I want to use a 2L bottle at 300bar with it.

Tuxing makes several versions of these compressors , the one in the pic , assuming it goes through, it was about 450 dollars and you do need cooling water. I have a 4.6 liter CF bottle and a 9 liter CF bottle I keep topped off with the pictured unit. My rifle has .6 liter on board air storage capacity and I can top that off in about 2 minutes or less. Takes about 15 minutes to top off my 4.6 liter bottle. Best feature is it’s a 120 volt standard current motor on the unit. It plugs right into the wall without the need of a power conversion unit. Cooling water sounds like a hassle , but I fixed a 5 gallon bucket full and added a gallon of coolant safe for aluminum radiators and it works perfectly and added coolant prevent mildew or mold from forming inside bucket. I think I did add one cup of chlorine bleach just to be sure. I’ve only made up the single bucket of cooling water. Never needed to change it for a year so far. I put royal purple oil in the compressor, they mentioned it by name in the manual. You can get different versions with added air filters and dryers installed on the compressor unit or you can get a striped down version that isn’t even mounted in a frame like mine , it just has a carry handle on top. I preferred the option mounted into the steel frame but purchased my own filters and dryers to send air through. 530 dollars is the amount of the compressor at the time I purchased it. The reason I went with it is I know a guy that owns a small airgun shop and he recommended those exact type tuxing brand machines. The machines that have low and high pressure compressor units separated rather than stacked up like on a Yong Heng unit has them configured. Mine does 310 bar and doesn’t run hot at all and I don’t add ice to cooling water sounds, unit stays well below max temp topping off 4.6 liter bottle. I have never reached max temp of 185 F , only about 145 to 150 topping off my 9 liter bottle which takes about 20 minutes.
