Mclovins spot on with the prices, they will only rent 232bar (3000psi) tanks, 12 or 15 ltr din fit, but you will have to find your own fill station with a purge.
Sab do have a B.O.C "K" size air cylinders on site which will fill to 3000psi when new. Depending who is there on site when you play someone may be able to help you out with air.
