Regulator Suggestions for tethered Line to Airgun?

"Eaglebeak"I have been using a product from Altaros air systems. It costs about 140 euro including postage. Its working range is between 80-210 bar. I have mine set at 170 and it works in the 165-175 range. If you want a higher working pressure, they may be able to build one to suit your needs. I have bought several products from this company and their service is highly regarded. The reg comes with hose and regulated pressure gauge and DIN type fitting which you will need if using a 300 bar bottle.
Which specific regulator are you talking about?

I have two for my AirForce(Gunpower) that work great.
 
"Inde"The problems with the above reg.is that you will not know the remaining pressure in the tank and it only fits a din 200 or din 300 scuba tank which are rare in the US. You can buy k valve to din adaptor. I also suspect the accuracy and readability of a gauge that size. The whole purpose of a reg. Is to eliminate pressure as a variable. I do not think this will achieve that.
The mano is indeed small but the reg is really accurate! I use one since a couple of months and am really pleased with it. I read the pressure from my normal filling set which I use accompanied by the regulator and the pressure is spot on. Make sure that if you use this regulator that a restriction in the filling set is gone, these restrictions kill consistency (this also holds for other regulators).

"Alan"Actually you can do it cheaper than $500. AoA now carries Huma regulators, and they make an adjustable one for the exact purpose.

This is a excellent reg and I own and use two of them 
they are very consistent and very trouble free been running
one for over 3 years now and not a single problem . 
 
Well I'm going to hit you with the cheapest untested one ..those $500 reg are not new is been used for years in the medical industry to reduce the pressure of those big oxygen tanks and other gases..to the hospital lines really surprised to find them at Ebay as low as $50 bucks .they come in different inputs and output pressure but there has to be one of those models that could be use for our application without having to spend that chunk of $$$$ but testing has to be made and I don't know anything about that's mater..I see them after I purchase mine..if not I do the testing my self..anyway those $500 reg has the China made stamp.
