I rebuilt a 5 hp ingersal ?rand about 25 years ago ,twin head cast iron , machined the heads , new gaskets , cleaned the tank , installed new reeds and been chugging away ever sense, new filter and oil.
Used to blast for prep but found the 5 hp 80 gallon tank just couldn¡¯t keep up,?
I use an air needle tool know for prep.
People that blast for me have BIG compressors.

On pressure, I run my Quincy QR325 with a 3HP motor at 400 RPM, soooo quiet at that low RPM.? Also I realized I don¡¯t need 175 psi, just heats up the
air more. I run at 120 psi.? I¡¯ve had no issue for years with an HVLP gun.? If I ever do I can change motors and pulleys and run with 5HP.

eBay was my solution, reportedly it was new old stock and the various fittings were from automationdirect.com. The main reduction regulator (Input 300 max-output 125 psi) can set up a harmonic in the tank when at full flow and whistle.
I can say the dial regulators are fantastic if you routinely need different pressures (turned off in the image, when the tank is on that gauge will show 80 matching the dial.) The regulators are 1/2" ensuring decent airflow.
