So does it consume more or less air on the high pressure side if you use a 125 psi air compressor?
If you had a SCUBA tank with 2500 psi in it and a carbon fiber tank with 3000 Psi could you then top the carbon fiber tank off at say 4000 or 4200 psi.
The reason I suggest toping of at less than the maximum 4500 psi is for a safety buffer.
I think I'll give you a call but there are others here dying to know/understand how this works.
Thanks for your patience ....I know you said you hate to type.
