This is a 1970 Military surplus 3000 psi Scuba compressor with the Kohler K161 7.5 HP gasoline engine. All cast iron engine, Rebuilt carb and fuel pump, Runs perfect. Fills the scuba tank from empty in about 15 minutes. 2 80cuft scuba tanks included, Must pick up in Rutherford, NJ 07070 500 firm. This is a steal. I have a video of it running and can email that but too big for here.
