Air Consumption

Suction Blast Nozzle Bore

Required cubic feet per minute(CFM) of air flow for a Air jet / nozzle combination at a set pressure.

e.g 1/8" Air Jet + 1/4" Nozzle - Running at 80 PSI, would require roughly 22CFM of air flow

		CUBIC FEET PER MINUTE
Air Jet Diameter	Blast Nozzle Diameter	40PSIG	60PSIG	80PSIG
1/16"	1/8"	3.5 CFM	4.5 CFM	5.5 CFM
1/8"	1/4"	13.5 CFM	18 CFM	22 CFM
3/16"	3/8"	30 CFM	40 CFM	50 CFM
1/4"	1/2"	54 CFM	75 CFM	90 CFM
4.0 mm	8.0 mm	20 CFM	25 CFM	30 CFM

Pressure Blast Nozzle Bore

Required cubic feet per minute(CFM) of air flow pressure blast nozzle at a set pressure.
