The minimum air flow (CFM) required depends on the nozzle orifice size and the blasting media being used. To ensure proper performance, maintain a minimum air pressure of 100 PSI at the blast pot.
The required minimum air flow for each nozzle size is listed below:
#2 (1/8 in.) – 21 CFM
#3 (3/16 in.) – 45 CFM
#4 (1/4 in.) – 80 CFM
#5 (5/16 in.) – 140 CFM
#6 (3/8 in.) – 200 CFM
#7 (7/16 in.) – 255 CFM
#8 (1/2 in.) – 340 CFM
#10 (5/8 in.) – 550 CFM
#12 (3/4 in.) – 800 CFM
