Learn how to properly size your piston compressor based on your needs
Air compressors should be sized based on the volume of air (cfm/m3h) and air pressure (psi/bar) needed to do the job and not horse power. Single stage air compressors have a maximum pressure of around 130 psi (9 bar) while two stage air compressors have a maxinum air pressure of 175 psi (12 bar). Tank size is typically not a critical factor in sizing a compressor.
