What compressor size is needed for each blasting pot size?

100L pot: 100-200 CFM at 7 bar (APEX-30). 200L pot: 150-300 CFM (APEX-45 recommended). 300L pot: 250-450 CFM (APEX-45 or dual APEX-30). 500L pot: 400-600 CFM (APEX-75 or dual APEX-45). 600L pot: 500-750 CFM (APEX-75 or dual APEX-75). All BLAST APEX pots are pressure-vessel coded and rated for 8 bar working pressure with 2x test pressure.

What abrasive media works in BLAST APEX blasting pots?

All BLAST APEX pots are compatible with: Copper slag (16-40 mesh) — most common, lowest cost. Almandine garnet (30-60 mesh) — reusability 5-8 cycles, preferred for coating prep. Steel grit (G40-G80) — aggressive profile, good for mill scale removal. Steel shot (S110-S330) — peen-forming and surface hardening. Glass beads (80-120 mesh) — cosmetic finishing, no profile. Never use silica sand — it causes silicosis and is banned in most jurisdictions.

What maintenance is required for a blast pot?

Daily: check abrasive level, inspect hose for wear, verify safety valve operation. Weekly: clean moisture separator, check gasket seals, inspect nozzle for wear (replace when bore diameter exceeds 125% of new bore). Monthly: check pressure vessel integrity, verify ASME/NACE code stamp is legible, test emergency blowdown valve. Annual: vessel hydro-test per code, full re-certification inspection.

What is the difference between suction-blast and pressure-blast pots?

Suction-blast pots (siphon guns): lower pressure (2-4 bar), single operator, lower consumption of abrasive, suitable for light coating removal and cosmetic work. Pressure-blast pots: 4-8 bar, high-velocity impact, Sa2.5 surface profile achievable, multiple operators possible with split valves. BLAST APEX manufactures pressure-blast pots — they are the industry standard for industrial surface preparation requiring Sa2.5 or better.
