Air Abrasive Machine

An air abrasive machine is useful for removing rust from the surface of an archaeological iron object or other surface corrosion on metal artifacts. The objects 'were cleaned' by a jet of abrasive powder (usually aluminium oxide) driven by compressed air inside a glass-top illuminated box. The cleaning intensity can be adjusted by simply controlling the air pressure and the powder flow rate. The waste powder will be contained inside the box and removed by a specialized vacuum pump, without contaminating the outside air.
