Bought a big *** air compressor today

[RJ Squirrel]

Went over to Montana and picked this up today, came from a sawmill that shut down a couple years ago. The air tank is a 500 gallon propane tank. I plan to drive the pump with my tractor PTO and use it for sandblasting, maybe a pumpkin cannon too. I just thought it was cool and had to have it!

Strange choice of words. A literal interpretation leads one to believe that that your *** needs a massive volume of outside sourced of air.

 

[RJ Squirrel]

Nah my *** does not need an outside source

That is indeed a big *** air compressor

Does it work?
Is it 3 phase?
What voltage does it require?
If your usage only requires intermittent short term uses during the day, you will have a hefty electrical bill if the entire system has any leakage.
A way to reduce that problem would be to have an auxiliary 60-80gal air tank, bypassing that propane industrial sized tank, that would fill up in a relatively short time looking at that compressor.
Using a PTO kind of voids these electric motor questions, but a PTO seems a bit brutish.
You could for that matter use any 5?hp compressor with the large tank as auxiliary storage capacity, and when sandblasting work 10minutes blasting and taking 15 minute breaks while air built back up?

That big 4 cyl pump will need a PTO to drive it. That actually may be more economical that a phase inverter. Congrats! I strongly suspect you might need an intercooler between the pump discharge and the tank, with a good moisture trap.

There are some asses out there that need compressing!
