Air abrasive systems

We are thinking about options for an air abrasive system for
overseas field work. The main application will be removing the
closely-adhered layers of sediment from the surface of lithics and
fossils.

Does anyone have experience of any kind of portable air abrasive
system or other set-up for this sort of application which might be
suitable to take on an international flight from the UK to Tanzania?
Ideally the pressure should be be adjustable between approximately
40 and 80 psi and the system should be capable of firing 29 micron
aluminium oxide powder.

The only option identified so far is a geological preparation 'air
abrasive blaster' supplied by UK GE, which would require a
compressor to be purchased on site but could be transported on a
plane. If anyone has experience with the UK GE model or any other
solution, we would be very grateful for your comments.
