FAQ
Nozzle size should be in relation to the capacity of the compressor. Note that at continuous working the compressor should not run at more than 5% of the capacity.
Air Pressure at the nozzle should be between 80 and 100 psi (closer to 100 psi cause the better performance). Remember to achieve high nozzle pressure.
Avoid blasting perpendicular (90 degrees) to the surface. An angle of 75-80 degrees gives the best performance.
The air hose between compressor and blasting unit should be as large as possible and as short as possible.
The grit valve should be set at a lean feed. Too much grit in the air flow results in low production and less profile. Start with the grit valve closed, open gently until you get the proper effect and leave it there. The grit coming out of the nozzle should look like a blue haze and not like a black cloud.
Optimum distance between nozzle and surface is about 30 cm (12 inch).
