LOW pressure, high volume

gas stations also don't have >1000 PSI.

just how much oil would it take to be a problem for electronics?

scuba tanks are more than 10 times the pressure usable for air
nozzles. But if you tap off of the primary regulator, you can get a
little over 100 PSI, which works nicely for nozzles.

You can get cheap air tanks for use at about 100 PSI, including crappy
kits from JCWitless for converting freon bottles into air tanks.

For the low pressure uses that wouldbe appropriate, you couldeven use a
tire.

expensive, hard to find when you need one, and off-topic for this list.
