Okay, I got fed up with taking my wife's tubeless road wheel to
the shop to get enough air into it to seat the bead when flat.
As such, not wanting to add a compressor to garage clutter, I
picked up an Airshot...

 Haven't had occasion to use it yet, but am hopeful it will do the
job when needed.
 In the meantime, I'm wondering if it could be used as an air
duster.  It has the valve core adaptor for dumping air into a
Presta valve with the core out.  This focuses the air down
somewhat, but a full 120 lb load of air was discharged in maybe
10-20 seconds.  I'm thinking some kind of fitting with a smaller
bore lumen would extend the dusting time, as well as increase the
dusting pressure.
 Any ideas where I should be looking?  So far, my searches have
been futile.

Those were common among the Pros when I was young I have one someplace.
What you want is some type of regulator to drop the pressure.  For your purposes it need not be expensive:

How to arrange the plumbing is another question.
