The Ingersoll Rand SS3L3 is a stationary single-stage compressor with a cast iron tank for durability. It is a continuous duty machine meaning it can run continuously without it overheating, but it also incorporates thermal overload protection and manual reset for protection. Excess condensation in the tank can be extracted via a manual drain located in a dificult-to-access location at the bottom of the tank. Note it has a 3/8" NPT outlet. It requires a 30A-rated, 230V household outlet and it is advisable to buy the start-up kit that goes with it as oil does not come with the compressor.
