i Spoke with the owner just a little bit ago on the phone and he said it was a 5hp, T-30, 60 gal, 2 stage, 220 volt, and it was used to blow off dust from parts in some type of optical cleaning buss he owns.
Thanks for the responses because it did help alot in making my decision to buy it. Cheapest i saw online in searching was 1k. The owner said if i came and got it today he would drop the price from 450 to 300.
So i bought it - its a big one and beats the heck out of my little pancake compressor.
Thanks to all ......Dan
