How many CFM does a sandblaster need?
The biggest consideration of proper blaster size is its compatibility with your compressor and nozzle. A 14 CFM at 90 PSI is compatible with a compressor at 35 CFM and 90 PSI, as long as the nozzle is rated at under 20 CFM.
What size of compressor do I need for sandblasting?
An air compressor which produces between 10CFM – 20 CFM is ideal for smaller sandblasting tasks. While a compressor which produces between 18CFM to 35 CFM is better for larger jobs where a more powerful experience is needed. While an industrial type of sandblasting needs a CFM of 50 – 100.
