How Many Fills Will I Get?
Estimates below assume: tank filled to 4500 PSI; refills counted until tank pressure drops to 3100 PSI (below that, full-pressure fills aren’t possible); 70°F; ideal-gas math — real-world fills vary with temperature and fill speed.
| Your gun’s air reservoir | Fill type | 6.8L tank | 9L tank |
|---|---|---|---|
| 500cc, filled to 3000 PSI | Full fill (empty → 3000 PSI) | ~6 fills | ~8 fills |
| 500cc, filled to 3000 PSI | Top-up (2000 → 3000 PSI) | ~19 top-ups | ~25 top-ups |
Smaller reservoirs or lower fill pressures = more fills. As tank pressure drops toward your gun’s fill pressure, fills get slower — plan a refill of the tank itself in time.
