You might think of this source too;
Years ago, I worked for an outfit that shipped big packages.  They had one of 
those deals that mixed two chemicals that would foam and fill the voids in 
shipping cartons.  Those two chemicals came in tanks similar to a propane 
tank, with one exception.  They were made to hook to an existing air line of 
125 psi..  The tanks came in Blue and Red, the red contained the foam and 
wasn't salvagable, but the blue one could be cleaned up and used.  I've got 
one in my shop I've had for twenty years.  NAPA makes a kit to retrofit these 
type of tanks with a gauge, filler nipple and a 3' hose that you can put a 
quick disconnect on.
