The gas-powered air compressors I'm familiar with two one of two things:

run constantly, venting compressor-air once tank pressure reaches
threshold.

or they run till they reach pressure, cut spark or fuel, and stop running.
when pressure reaches the lower threshold, they refire themselves.  More
complicated, and requires an engine that starts easy...:)


The former is easier, and you can probably find a pressure regulator to do
exactly that at a compressor supply house...
