Compressed air consumption
The compressed air consumption of a blasting machine is only determined by the following factors:
Direct pressure method (one hose):
- Diameter of the blast nozzle
- the blasting pressure.
Suction feed method (two hoses to the blastgun):
- diameter of the air nozzle inside the gun
- the blasting pressure.
Blastpot contents, piping or hose diameter do not influence the consumption.
The following table shows you the compressed air consumption with different diameters and blasting pressures:

Our New Zealand distributor posted a nice YouTube video of soda blasting an old Land Rover. For this demo they used the small Gritco Pequena-MSÂ with just a 4 mm nozzle. The soda media is the ARMEX Maintenance XLÂ formula. For commercial use you can work even faster using large nozzles together with our MicroStrip machine!
