40 CFM Boss diesel air compressor, very limited use, I had a smaller air compressor for everyday use, this was only used for 3/ 4 and 1" rattle gun use on the rare occasion. Comes with a box full of spare filters etc. Oil always changed whether it needed it or not. Has rusty coloured Mark' s on tank where the cover rubbed up against it. No further use. Contact for more details. Will freight at buyers expense.
