Single Stage and Two Stage is in reference to the compressor pump type. The pump takes the ambient air and compresses it into the tank. In general Single Stage pumps can deliver up to 155 PSI and have CFM ratings shown below 100 PSI. Single Stage pumps compress the air directly into the tank. Two Stage pumps can deliver 175 PSI or more and have CFM ratings at 100 PSI and above. Two Stage pumps compress the air in the first stage then pass it to the second stage where it is compressed again. Determining your air requirements will determine if you need a Single Stage or Two Stage pump.
