Generally speaking, it is often said the cost of electricity used is more than purchasing the machine! Yes, air compressors do consume a lot of electricity. On average, about 75 percent of the lifetime cost of it is just electricity.

The size required for sand blasting can be divided into three types, as follows:

  • Smaller sandblasting – 10 – 20 CFM
  • Larger sandblasting – 18 – 35 CFM
  • Industrial sandblasting – 50 – 100 CFM
CFM is Cubic Feet per Minute, and SCFM is standard Cubic Feet per Minute. SCFM represents the gas volume rate of flow when checked in a standard environment like the standard temperature and pressure etc. CFM is air volume that is measured on any exact pressure or temperature.
Let the regulator down, and the air starts to flow inside the tank, and a low pressure builds up. This less pressure will certainly increase the CFM in the air compressor.
Smaller air tools require 0 to 5 CFM and larger tools generally require more than 10 CFM.
