° The air nozzle always has a smaller bore diameter than the blast nozzle (less air requirement).
° The compressed air and the blasting media are fed to the blasting gun via two separate hoses.
° The blasting media is accelerated in the blasting nozzle.
° The systems can be easily automated, as no transport or conveying equipment is required for the blasting agent.
° Immediate blast power when switched on, since, for example, no pressure has to be built up in advance.
