I miss my Campbell Hausfeld 5hp horizontal twin cyl. (home owner 'Heavy Duty'..) 26 gal. on wheels compressor.I sold it out of my storage(which had no elec. otherwise i would have kept it)in Eastern PA. 5 yrs. ago,gave the new owner a great deal too,it had less than 100 hrs. run time on it.That one you have there Harsh is Commercial Duty,should be 'just what the Dr. ordered' for your needs w/ the sandblast cabinet & painting,etc.
