This is probably too obvious, but no power hammer should be running
directly off the compressor any way, so why not put in a larger storage
tank?
I ran my bull hammer for a short while off of one of those little
compressors that roofers use and a larger tank.
It was very hard on the little compressor as they have short duty
cycles, but the hammer didn't care at all.
For the small one person shop there is usually enough down time between
heats for the smaller compressor to refill the tank.
I have since gone to a big honkin' two stage, but that is because I now
am set up to run other things off of air and have the potential of
having more than one tool in use at a time.
For a short while I considered twinning a smaller compressor into the
system and setting the switch at a higher on point than the two stage.
Running the numbers it looked like the energy consumption would not have
changed much. Compressing a given volume of air to a set pressure just
required the same amount of energy.
I do have the smaller unit piped in as a backup at the other end of the
piping, but not turned on, strictly a reservoir. This also helps
alleviate possible pressure drop issues due to piping size, if I fire up
too many pieces of equipment at the far end of the piping.
