What Size of Compressor Do I Need for Sandblasting?

Air Compressor Requirements for Sandblasting

  • CFM and PSI Ratings: For sandblasting, you’ll need an air compressor with a CFM rating of at least 15-20 and a PSI rating around 100-120. HP should be in the 10-15 range, and the tank size should be around 40-60 gallons or higher.

  • Considerations for Sandblasting Projects: To run a sandblaster effectively, you need an air compressor with 90 to 100 PSI. If it drops below 50 PSI, the pressure won’t be sufficient to take material off.

  • Size and Pressure Requirements: While a compressor producing 18-35 CFM is suitable for most jobs, industrial sandblasting demands compressors with 50-100 CFM.

  • Sizing Factors: Compressors and sandblasters are sized based on CFM (cubic feet per minute) and PSI (pounds per square inch).

  • Choosing the Right Compressed Air Machine: Ensure you select the appropriate air compressor based on your sandblasting project needs. Use these guidelines to make an informed decision.
