... He suggested I make some changes and get a different blast gun and hose and it has made a big difference in run time with no noticeable loss in performance. ...

Could you elaborate please, on the gun change? Did you replace the gun with one having a smaller orifice, or only replace the orifice in the original gun?
We bought a Campbell - Hausfeldt 80 gal. compressor rated 16CFM @90 PSI, just making the cut for our VHT cabinet. It's single stage, but the pump is four cylinder, so it moves more volume per rev than most two cylinder units we looked at. Still, it runs a lot. We generally have the regulator set to 75 PSI at the cabinet. 3/4" I.D. supply hose.
Good Ridin'
