IMHO the only piping that should be used with compressed air is iron pipe.  
Besides being strong enough to handle 125-150 psi without problem, it also 
allows the moisture in the compressed air to condense out thus reducing the 
demand on your in-line water traps.  PVC might be fine for sewer lines, but not 
for air.

Hi,
While we're on the subject of air tools, there's what seems to be 
a continuous thread about what to use to plumb air in your shop...
This month's Fine Homebuilding has a small blerb about why you
shouldn't use PVC air for plumbing - the "guru" claims its because the
PVC pipe's strength is seriously compromised by temperature - I don't
have the article here, but his points did seem to make sense...
