The selection of Air Blasting equipment, commonly used for Sand or Shot blasting, involves Dry, Wet, and Soda Blasting or similar processes, where abrasives are blown out of the nozzle by a stream of pressurised air.
The Air Blasting process is a special technique where compressed air forms pneumatic acceleration of abrasive media through the nozzle to the surface. With different abrasive media, size and type of blasting nozzle and various levels of air pressure, controlled impact coverages are achieved on the surface.
Air Blasting techniques
You can choose among the following Air Blasting techniques:
-Injector (vacuum – siphon) Blasting
Air blasting can be applied in different ways.
Injector Blasting, where abrasive media is delivered by means of negative pressure into the gun, or Pressure Blasting, where compressed air and abrasive media are mixed within the blasting generator (pressure pot) before delivered through the hose into the nozzle.
Both techniques can also be used in dustless Air Blasting, where blasting media is collected immediately after hitting the surface, preventing dust or media to be released into the atmosphere or open space. In special circumstances, where the surface is very sensitive, Wet Blasting or Soda Blasting is applied. This type of application can often be replaced with a similar Dry Ice/Dry Snow Blasting/Cleaning technique.
The Wet Blasting process is a special technique where water, abrasive media and compressed air are mixed and delivered to the surface through the nozzle. It is much softer, gentler and non-aggressive, with a controllable surface impact.
Like Dry Blasting, Wet Blasting machines can also be delivered in different options; from the simple injector to the powerful pressure types that come in a number of variations.
Wet blast machines are often applied in environments where the risk of explosion exists (for blasting titan, magnesium, aluminium alloys, etc.).
