John I hope this helps
Air pressure can be varied from 20psi on soft surfaces to 120psi on harder surfaces.

The following list compares the blast nozzle size to the compressor CFM requirements


Nozzle H.P. Compressor

# 3- 3/16" 10 H.P. 45 CFM

# 4- 1/4" 20 H.P. 80 CFM

# 5- 5/16" 30 H.P. 140 CFM

# 6- 3/8" 50 H.P. 200 CFM

# 7- 7/16" 60 H.P. 255 CFM

# 8- 1/2" 75 H.P. 350 CFM

I use a portable system on lone from a family member but I have found this same system for aprox $250.00 . Larger models about $1800.00 My compressor is also a loner from family it is a 200 CFM unit
