<div class="moz-cite-prefix">Dear Rebecca,<br>
<br>
you need to consider two aspects when shipping this unit as air
freight:<br>
<br>
1. The machine/compressor must either be new (with a respective
certificate of the manufacturer) or the tank of the machine needs
to be clean(ed). Otherwise the (used) compressor has to be sent as
air dangerous goods which would require to hire a specific company
for packing & marking if you / your institution does not have
a IATA certified person that could offer the consignment for
shipping. <br>
<br>
We did ship once a new compressor to re-fill scuba diving tanks to
Cameroon, and once we tackled down all (potential) IATA issues,
the shipment got stuck at Cameroon Customs and was not released,
until the field team had to return. After this, all traces of the
machine disappeared, and we never got it back.<br>
<br>
2. The Aluminium (oxide) powder might be mistakenly considered to
be restricted either as Aluminium powder, coated (UN1309) /
Aluminium powder, uncoated (UN1396) or as Metal powder, flammable
(UN3089) or self-heating (UN3189); metal oxides should be stable
and non-reactive. It might be worth to check this with your air
line / air cargo carrier and to make sure that no pure metal
powders are included. Otherwise fine glass powder used as abrasive
might offer an alternative in case of troubles with the carrier.<br>
<br>
Hope this is of help<br>

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.<br>
<br>
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 c. 40 and 80 psi and the system should be
capable of firing 29 micron aluminium oxide powder. <br>
<br>
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. <br>
