What Compressor Are You Using Top Off At 300B?

So I run the alkin which I love fills my scbas with ease. I have a few pcps in the lineup that I use at 300/310b and the scba gets close but I want a full top off. I have the xsciso which is was the better version of the cs3 when it came out that has the little oil coiling feature. It has done great but I think going from 275/280/290 range up to where I want to top of at 300B+ will eventually fail it's alot of work at that pressure. I was thinking of getting the CS4-I for this specific task but was wondering what suggestions you all have or use. Thank you for the info.

The cs4 models will do it. Advantages of course are...
The Cs4 is fairly quite for a compressor
You can take it, and your tanks with you. Refill as you shoot.
And of course you can fill your guns directly if ever desired.

I ran a Yong Heng for a couple years, sure it was faster... but it's loud, needs support such as a water source, and you're not taking that thing with you anywhere.

If you go with GX order directly from them or Amazon. I do sell some open box and refurbished ones on Ebay.

 
The air ventury Krypton is an amazing compressor and is quiet. My buddy got one from a pawnshot for $350!! They retail for $1500, it's what I was using to top off my gk1 and K1 to 350b when I had them. Unfortunately the motor threw a piston when we accidentally set the stop gauge to high. (Distracted doing other airgun stuff), accidentally filled an scba tank to 5500. Nothing happened to the tank fortunately.

It's mainly just to top the guns off i let my alkin auto shutoff at 310b on the scba tanks so when I want to top off the pcps that's all I'm really looking for.
 
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……..
 
I will have to see the operation of it but yes no more buckets of ice water preferred.
The CS4 is internally water cooled..No buckets of water...I just got a CS4 for topping off SCBA tanks and filling pcp tanks..Im pretty impressed with initial perfotmance if cs4..I have used a yong heng for three years,,i put about 10 pistons in it along with various other repairs..I bought my cs4 on ebay used refurbished for $350.00 and $55.00 shipping.. I will tell you in year how good the cs4 is... It fills quiet ,safe, pretty easy to use...
