Do you know what the SCFM rating is at ~100 psi? That is more likely 
where you'll want to set the pressure for sandblasting. 

I suspect you've got an adequate air supply - especially for small 
items in a small cabinet. More important is a supply of dry air. 
Blasting does not like wet air. A run of metal pipe (copper or steel) 
will encourage the air to cool down and the water to condense out. Plan 
the air line leading to the cabinet such that it will not come off the 
bottom of a run to keep water out. 

See the air piping instructions at
