hi, i have access to free cylinders/air through my dads work. i charge my gun to 3000psi (approx 207bar?) i need to know (may sound stupid) what cylinder do i need?
i have access to a 600litre cylinder at 207barr and i can get access to a 1800 litre 207bar cylinder. will these both be suitiable? and how long/many refills are these likely to last? many thanks, Ross
