gimmick wrote:He may be confusing H2O vs HPA capacity of his 67cuin tank. i.e. his tank has 67cuin of H2O volume but actually contains 67cuin*207bar/1728cuin= 8cuft of compressed HPA at 3000psi - which takes four hours to fill. Four hours at 8cuft translates to 44 hours at 88cuft assuming the pump system is linearly efficient.
I suspect the first stage compressor cfm plays a large part in the overall system. I wonder if a 120psi vs an 80psi shop compressor would significantly affect the fill rate of a tank and whether it becomes less of a factor as the tank approaches its final pressure?
For the AF tank at 490cc = 29.9cuin*207bar/1728cuin=3.58 cuft (at 3000psi)
My head hurts.

Mam, it is built for continuous duty.

Any airgun that gets enough shots to allow it being topped up over night
I was of the opinion that filling a SCUBA or such was beyond its capability but Tom corrected my thinking and said it will do it. Just need to allow the time. With the auto kick out just let her buck!

My only concern is the moisture aspect. I know you can install a filter but I'm worried about the long term effects of people using the compressor chain without any moisture removal... The AF tanks are manufactured by Catalina's Cliff Impact Division... and the aluminum spec is most likely the same as SCUBA, i.e. tested and designed for breathing quality air. What happens when you repeatedly compress moist air between you're 5 year hydro's?
gimmick wrote:If moisture is no concern then why do our tanks need to be VI/12mo and HST/60mo by DOT and CT standards? And why does our SCUBA shop need to spend a fortune on moisture filters for their compressed air?
AL oxidizes too.
