About Air Compressors for Sandblasting
Tiny 1.5mm cabinet blast nozzles draw around 5 CFM at 80 PSI. Step up to a 4–5mm pot blaster nozzle and you'll demand 15–25 CFM continuously. For sustained large-area blasting, a rotary screw compressor or a twin-stack of belt-drive units is normal.
Always run an in-line moisture trap and desiccant dryer — wet abrasive blocks instantly. A larger tank (200L+) lets the compressor catch up between bursts.
Strong UK picks for sandblasting include the Hyundai HY3150V, SIP Airmate ISBD15/270 and any 7.5–11kW rotary screw compressor.
