PSI regulator...

Usual method is the air regulator and moisture trap are one unit, attached to the compressor, followed by the hose and airbrush.

Don't need anything too fancy, something like the one below is cheap:

I don't know which model you have, so I can't say how easy it would be to add a regulator.  But, if a connection can be made, it should be possible.

20 psi is a pretty good pressure for many airbrushes.  My suggestion is that if you're getting the results you want, don't mess with it.  Is there a reason you want to crank the pressure down?

Is there a reason you want to crank the pressure down?

I would like to get less pressure for closeup work so that I do not get the spider web effect

One problem is that there will be a pressure drop across the new regulator. If you add it in addition to your existing one, you may not be able to get a high enough pressure when you want it.  You may find a max available of, say, 12-14 psi.  You may need also to see what the basic pressure of the compressor is.  That may be the problem rather than the regulator.  If the compressor only puts out- say- 25 psi, a 5 psi drop through the  built in regulator may limit the output pressure to 20.

Here's a no-cost trick you could try.  Some compressors, like the Iwata SmartJet, don't have a real regulator.  Instead they have a controlled air leak.  You could do the same thing by just slightly loosening the hose connection at the compressor.  Crude, but it might work for you.
