Reply To: 480cc bottle fill with a hand pump ?
oh ok thanks ! ^^
I might have found the “solution” on the FX website, they say that the pump moves 300cc of air, at 1 ATM, so i tried something… 480cc is at 1ATM ? right ? so 480cc of air at 250 BAR should be 120 000cc (yeah thats not really accurate but at least im trying ^^) so, to fill those 120 000cc with the pump, it would require me 400 pumps, + the loss from the bleeding valvle, you where right, it should be around 500
So now, if my math are correct (and im not sure about it, at all) if i use the gun from 220 BAR down to 140, i would have to pump only 128 times to re fill it up to 220 BAR !
i hope i’m right ^^
