What is the purpose of an air receiver in a blasting system?

An air receiver (blowdown tank) provides: (1) Pressure stabilization — smooths compressor pulsation for consistent blast pressure. (2) Surge capacity — stores compressed air to handle peak demand when multiple operators blast simultaneously. (3) Condensate separation — allows moisture to settle out before air enters the blast pot. (4) Emergency air reserve — provides 2-5 minutes of blast time if compressor trips unexpectedly, allowing safe operator shutdown.

Should air receivers be vertical or horizontal?

Vertical receivers are preferred for workshop/fixed installations — they have a smaller footprint and moisture drains from the bottom drain valve more effectively. Horizontal receivers are used for mobile skids, height-restricted spaces, and mobile blast rigs where the low profile allows the receiver to sit under a compressor or inside a container. BLAST APEX offers both orientations.

What pressure rating is required for blasting air receivers?

Blasting systems typically operate at 7 bar working pressure. Air receivers must be rated at minimum 1.5x working pressure per ASME Section VIII — so 10.5 bar minimum. BLAST APEX receivers are rated 11 bar working / 16.5 bar test pressure. For high-pressure applications (10 bar blast), specify the HP variant rated for 15 bar working.

Compressed Air Storage

Industrial
Air Receivers

BLAST APEX manufactures high-capacity industrial air receivers designed for pressure stabilization and air storage in high-volume blasting and coating systems. Our vessels act as a vital buffer between the compressor and the blasting pot, ensuring a constant pressure flow and reducing overall energy consumption.

Horizontal	200-500L	11 bar / 16.5 test	Mobile blast rigs, height-restricted spaces, skid-mount applications
High Pressure	50-200L	15 bar / 22.5 test	High-pressure blasting (10 bar+), specialized coatings, test pressure requirements

Frequently Asked Questions

What pressure rating do I need for sandblasting air receivers?

Standard industrial sandblasting: 11 bar working pressure receiver. For multi-nozzle setups (3+ operators) or high-pressure systems: 15 bar receiver. Oversizing pressure rating is always safer and extends vessel life. Receivers must be ASME Section VIII code-stamped. For portable compressor setups, the receiver is typically included with the compressor package — verify the receiver meets the compressor's maximum pressure output.

What size air receiver do I need?

Receiver size = (CFM × 0.25 to 0.5) for continuous blasting. Example: APEX-45 (450 CFM) → receiver 150-225L minimum for smoothing air pulses. Larger receivers (450-600L) reduce compressor cycling and provide smoother air supply during intermittent demand peaks. For 24/7 operations, always specify the larger receiver size — the marginal cost difference is small compared to compressor wear from cycling.

How often must air receivers be inspected?

ASME-required: internal inspection every 5 years, hydrostatic test every 10 years. Daily: drain condensate (automatic drain valve recommended). Monthly: check pressure gauges for accuracy, inspect for external corrosion, verify safety valve operation. Annual: professional inspection by registered engineer. Maintain inspection logs on-site — required for insurance and warranty claims.
